Description

  The present invention relates to a vibration damping structure that suppresses deformation of a structure due to an earthquake, strong wind, or the like.

  The following methods (a) to (d) have been proposed in order to suppress building deformation caused by earthquakes, strong winds, and the like and to improve building safety.

  (A) A damper member is installed on the building frame. (B) An auxiliary structure is provided outside the building, and a damper member is installed between the structure and the building. (C) An additional weight body is provided in the upper layer of the building, and a damper member is installed between the additional weight body and the building. (D) The building is divided by an intermediate layer, and a damper member is installed in the divided intermediate layer.

  However, the method (b) is costly because an auxiliary structure must be separately manufactured and installed, and an installation space for the auxiliary structure must be secured around the building.

  Further, in order to exert a sufficient damping effect against earthquakes and strong winds by the method (c), the additional weight body must be made huge.

  Furthermore, since the method (d) divides the intermediate layer of the building, the safety of the building is reduced, and the installation of the damper member requires special reinforcement, etc. Become.

  Therefore, in general, the method (a) is often used as means for suppressing deformation of a building against earthquakes and strong winds.

  However, if the proportion of bending deformation is large among the deformations that occur in the building due to the high-rise building, the effect of suppressing the bending deformation of the building cannot be obtained sufficiently even if the method (a) is used. There is a problem that the effect of the damper member that suppresses the shear deformation generated in the building is reduced by the bending deformation.

  For example, as a mode of installing a damper member on a building frame, the vibration control mechanisms 200, 202, 204, 206, 208, 210, 212, 214, and 216 of FIGS. 25 to 27, a frame 218 including columns 220A and 220B, beams 222A and 222B, a brace material 224, an intermediate column 225, a resistance plate 226, rod-shaped damper members 228A and 228B, a bundle-shaped damper member 230, and a wall-shaped damper member 232 are illustrated. It is shown.

  Here, as shown in FIG. 28, when a horizontal load F is applied to the vibration control mechanism 200 of FIG. 25A from the left to the right, and shear deformation and bending deformation occur simultaneously in the building, The beam 222A on the floor and the beam 222B on the lower floor relatively move in the horizontal direction due to shear deformation generated in the building. That is, the beam 222A moves to the right with respect to the beam 222B.

Thus, the binding portion _{S 1} between the lower end portion and the beam 222B of the rod-like damper members 228A arranged on the left side of the Frame 218, coupling portions _{S 2} between the upper portion and the beam 222A of the rod-like damper members 228A are arrows M Move to the right as shown in ₁ . Then, the rod-like damper member 228A with the movement of the coupling portion S ₂ can therefore extend obliquely upward (arrow M ₂₎ which exerts a damping effect, to suppress the shear deformation occurring in the building.

Also, the bending deformation acting on the building, arranged pillars 220A on the left side of the Frame 218 extends, but shrinks pillars 220B disposed on the right side, the direction on the coupling section S ₂ accompanied thereto (arrow R ₁₎ The amount of movement d is considerably small or not. Furthermore, since the movement coupling portions S ₁ also upward, the elongation amount of diagonally upward of the rod-like damper members 228A (arrow R ₂₎ is small or no, no sufficient damping effect can be obtained. Therefore, the bending deformation generated in the building cannot be effectively suppressed.

  In addition, as shown in FIG. 29, when a horizontal load F is applied from the left to the right in the vibration control mechanism 212 of FIG. 27A and shear deformation and bending deformation occur simultaneously in the building, the shear generated in the building Due to the deformation, the upper floor beam 222A and the lower floor beam 222B of the frame 218 relatively move in the horizontal direction. That is, the beam 222A moves to the right with respect to the beam 222B.

Thus, the binding portion _{S 1} between the lower end portion and the beam 222B of the rod-like damper members 228A arranged on the left side of the Frame 218, coupling portions _{S 2} between the upper portion and the beam 222A of the rod-like damper members 228A are arrows M Move to the right as shown in ₁ . Then, the rod-like damper member 228A with the movement of the coupling portion S ₂ can therefore shrink diagonally downward (arrow M ₂₎ which exerts a damping effect, to suppress the shear deformation occurring in the building.

Also, the bending deformation occurring in the building, arranged pillars 220A on the left side of the Frame 218 extends, but shrinks pillars 220B disposed on the right side, the coupling portion S ₂ in accordance with the this upwardly (arrow R ₁₎ The rod-shaped damper member 228A extends obliquely upward (arrow R ₂ ).

However, the rod-shaped damper member 228A contracts due to the shear deformation that occurs in the building (arrow M ₂ ), and extends due to the bending deformation that occurs in the building (arrow R ₂ ), thereby canceling out the deformation amounts of each other. Therefore, not only the bending deformation generated in the building cannot be effectively suppressed, but conversely, the effect of the rod-shaped damper member 228A that suppresses the shear deformation generated in the building is reduced by the bending deformation.

28 and 29, the effect of the damper member that suppresses the shear deformation and bending deformation generated in the building is verified for all the vibration control mechanisms shown in FIGS. 25 to 27. The arrow B _{1 in} FIG. , C ₁ and C ₂ are shown to show any tendency.

The graph of FIG. 30 shows the efficiency against shear deformation on the horizontal axis (the magnitude of the effect of the damper member that suppresses the shear deformation generated in the building), and the efficiency against bending deformation on the vertical axis (the damper that suppresses the bending deformation generated in the building). The magnitude of the effect of the member) is shown. The lengths of the arrows A ₁ , A ₂ , B ₁ , C ₁ , and C ₂ indicate the magnitude of the effect.

Damping mechanism 200, 202, 204 in FIG. 25 (A) ~ (C) has a characteristic of arrow _{B 1.} Damping mechanism belonging to the group of the arrow B ₁ represents, the efficiency is greater for the shear deformation of the building, the efficiency to bending deformation becomes smaller.

Damping mechanism 206, 208 and 210 of FIG. 26 (A) ~ (C) has a characteristic of arrow _{C 1.} Damping mechanism belonging to the group of arrows C ₁ is the efficiency high for shear deformation of buildings, efficiency for bending deformation is negative, as described in FIG. 29, effectively suppressing the bending deformation occurring in the building In addition to not being able to do this, conversely, the effect of the damper member that suppresses shear deformation occurring in the building is reduced by bending deformation.

Damping mechanism 212, 214, 216 in FIG. 27 (A) ~ (C) has a characteristic of arrow _{C 2.} Damping mechanism belonging to the group of arrows C ₂ is thus reduced further by the effect of the bending deformation of suppressing the damper member shear deformation occurring in the building than the vibration damping mechanism belonging to the group of the arrow C _1.

As a vibration suppression mechanism that has a high efficiency with respect to bending deformation of the building and does not reduce the effect of the damper member that suppresses shear deformation of the building by bending deformation, it is desirable to have a characteristic as indicated by arrows A ₁ and A ₂ . Such a damping mechanism has not been proposed so far.

  As shown in FIG. 31, in the earthquake-proof reinforcement structure of Patent Document 1, a pair of high-strength reinforcement frames 236A and 236B are arranged side by side in the same plane, and a vibration damping device 238 is provided between the reinforcement frames 236A and 236B. is set up.

When shear deformation occurs in the building 240 due to an earthquake, the pair of reinforcing frames 236A and 236B arranged in parallel rotate, and a relative displacement in the vertical direction is generated between the reinforcing frames 236A and 236B. Operate. For example, when a pair of reinforcing frames 236A, 236B is rotated rightward, respectively, the point _{E 2} at the left end of the reinforcing frame 236B is moved to the relatively higher position than the point _{E 1} at the right end of the reinforcing frame 236A.

  Therefore, the shear deformation of the building 240 at the time of the earthquake is restrained by the reinforcing frames 236A and 236B, and the vibration damping device 238 absorbs the vibration energy and obtains the vibration damping effect.

However, if the bending deformation with shear deformation in the building 240 has occurred, the left reinforcing frame 236A is considered to be in relatively higher position than the right reinforcing frame 236B, the point E ₁ and the point E _2, the reinforcing frame Thus, the positional relationship of reducing the amount of displacement due to the clockwise rotation of 236A and 236B is obtained.

  Therefore, since the relative displacement amount between the reinforcing frames 236A and 236B becomes small, it is considered that the vibration damping effect by the vibration damping device 238 cannot be sufficiently exhibited. In addition, since a reinforcing frame as an auxiliary structure must be separately manufactured and installed, costs increase.

  As shown in FIG. 32 (A), in the damping structure of Patent Document 2, a plurality of damping columns 244 are arranged around the tower-shaped building body 242 and the lower end of the damping column 244 is It is fixed to a foundation (not shown) formed on the ground 246. Further, the vibration control pillar 244 and the building main body 242 are pin-coupled via a large number of links 248 and further coupled by a large number of dampers 250.

  When the building main body 242 is bent and deformed by an earthquake, the bending moment of the building main body 242 is not transmitted to the vibration suppression column 244 as shown in FIG. Deformation does not occur. Therefore, each section surrounded by the link 248, the building main body 242, and the vibration control column 244 is greatly deformed.

  Therefore, the damper 250 provided in the compartment resists this deformation and suppresses the bending deformation of the building body 242.

  However, the control column 244 requires high rigidity, and the space between the building body 242 and the vibration control column 244 becomes a dead space, so that the building becomes less economical.

  As shown in FIG. 33, in the vibration control frame structure of Patent Document 3, the uppermost truss 256 and the intermediate truss 258 in which an unbonded brace damper 260 is assembled in a truss shape at the top and middle of a building 254 having a core wall 252. Is provided.

  When the building 254 undergoes bending deformation due to an earthquake, the core wall 252 is bent back by the uppermost truss 256 and the intermediate truss 258 to relieve the deformation, and vibration energy can be absorbed by the unbonded brace damper 260.

  In the vibration control frame structure of Patent Document 3, an excessive amount of axial force generated in the peripheral column when the core wall 252 is bent back by the rigid top floor truss 256 and the intermediate truss 258 is suppressed by the unbonded brace damper 260. be able to. However, at the same time, the rigidity of the uppermost truss 256 and the intermediate truss 258 is also reduced.

  As shown in FIG. 34, in the eccentric brace structure 262 of Patent Document 4, the first eccentric brace 270 is disposed between the lowermost beam 266 and the uppermost beam 268 in the three-layer section of the frame 264 constituting the building 272. Has been. An upper end portion of the first eccentric brace 270 is joined to the uppermost beam 268 via a bundle member 274. In addition, second eccentric braces 278 are arranged at each level of the frame 276 located in front of FIG.

  Therefore, by arranging the first eccentric brace 270 across a plurality of layers, the bending deformation generated for each layer of the frame 264 can be taken out in a plurality of layers and received by the first eccentric brace 270 and the bundle material 274. In addition, the elastic-plastic deformation behavior of the first eccentric brace 270 and the damper effect of the bundle 274 can be effectively functioned.

  In addition, since the second eccentric brace 278 is provided in each layer together with the first eccentric brace 270, the vibration damping effect of the building 272 can be further improved in combination with the first eccentric brace 270.

However, since the configuration of the eccentric brace structure 262 of Patent Document 4 is the same as that in FIG. 25C, the efficiency with respect to the shear deformation generated in the building 272 is large, but the efficiency with respect to the bending deformation is reduced. Therefore, a sufficient vibration damping effect for the bending deformation of the building 272 cannot be expected.

  In view of such facts, an object of the present invention is to provide a damping structure that suppresses shear deformation and bending deformation generated in a structure and does not reduce the effect of suppressing shear deformation by bending deformation.

  The invention according to claim 1 is a damping structure having a damping mechanism arranged across a plurality of layers of the structure, and an upper beam provided at the top of the plurality of layers, and an uppermost beam of the plurality of layers. A lower beam provided at a lower portion; an intermediate member provided between the upper beam and the lower beam; and a support member that is vertically provided to join the upper beam and the lower beam. The damping mechanism is disposed between the upper beam and the intermediate member, or between the lower beam and the intermediate member, and a damper member that is deformed when shear deformation occurs in the structure. The damper member is not disposed, is disposed between the upper beam and the intermediate member, or is disposed between the lower beam and the intermediate member, and is connected to an end portion of the damper member to support the support member Rigidity to transmit the axial deformation of the damper to the damper member A deformation direction of the damper member when a shear deformation occurs in the structure, and a bending member of the damper member when the support member deforms in the axial direction due to a bending deformation of the structure. The rigid member is arranged so that the deformation direction is the same.

  In the first aspect of the present invention, the damping structure is constructed by arranging the damping mechanism across a plurality of layers of the structure.

  The vibration control structure is composed of an upper beam provided at the top of the multi-level, a lower beam provided at the bottom of the multi-level, an intermediate member provided between the upper beam and the lower beam, and standing up and down. Having a supported member. Moreover, the upper beam and the lower beam are joined to the support member.

  The vibration damping mechanism includes a damper member and a rigid member.

  The damper member is disposed between the upper beam and the intermediate member, or between the lower beam and the intermediate member. The damper member is deformed when shear deformation occurs in the structure.

  The rigid member is disposed between the upper beam and the intermediate member, or between the lower beam and the intermediate member, where the damper member is not disposed. The rigid member is connected to the end of the damper member and transmits the axial deformation of the support member to the damper member.

  Furthermore, in the rigid member, the deformation direction of the damper member when shear deformation occurs in the structure is the same as the deformation direction of the damper member when bending deformation occurs in the structure and the support member deforms in the axial direction. It is arranged to be.

  Therefore, when a horizontal force is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure, first, the upper beam and intermediate member, and the lower beam and intermediate member are subjected to shear deformation generated in the structure. Move relative to the horizontal.

  At this time, the damper member disposed between the upper beam and the intermediate member or between the lower beam and the intermediate member is deformed along with this relative movement, so that a damping effect is exerted, and shear generated in the structure. Deformation can be suppressed.

  Further, the support member is deformed in the axial direction when bending deformation occurs in the structure.

  At this time, the shaft of the support member is not provided by the rigid member which is disposed between the upper beam and the intermediate member or between the lower beam and the intermediate member and is connected to the end of the damper member. Since the deformation in the direction is transmitted to the damper member, the damper member is deformed and exhibits a damping effect. Therefore, bending deformation generated in the structure can be suppressed.

  Also, the deformation direction of the damper member when shear deformation occurs in the structure is the same as the deformation direction of the damper member when bending deformation occurs in the structure and the support member deforms in the axial direction.

  By these, the shear deformation and bending deformation which generate | occur | produce in a structure can be suppressed, and the effect of the damper member which suppresses the shear deformation generate | occur | produced in a structure is not reduced by bending deformation. Moreover, the structural safety | security of a structure improves by suppressing the bending deformation of the structure which was difficult conventionally.

  According to a second aspect of the present invention, the support member is a column erected on or near the outer periphery of the structure, and the intermediate member is provided between the upper beam and the lower beam. The damper member is a beam joined to the column, and the damper member is disposed obliquely toward the inside upper side of the structure with a lower end coupled at a junction between the column and the lower beam, and the rigid member is The upper ends of the pillars and the upper beams are joined at the joints and arranged obliquely toward the inner lower side of the structure, the upper ends of the damper members, the lower ends of the rigid members, and the beams. It is characterized by being connected.

In the invention according to claim 2, the support member is a column erected on or near the outer periphery of the structure,
The intermediate member is a beam provided between the upper beam and the lower beam. Moreover, this beam is joined to the column.

  The lower end portion of the damper member is coupled at the joint portion between the column and the lower beam. In addition, the damper member is disposed obliquely toward the inside upper side of the structure.

  The upper end portion of the rigid member is coupled by a joint portion between the column and the upper beam. Moreover, the rigid member is diagonally arranged toward the inner lower side of the structure.

  Further, the upper end portion of the damper member, the lower end portion of the rigid member, and the beam are coupled.

  First, the action and effect of the vibration control mechanism arranged on the left side of the structure when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur at the same time will be described.

  Due to the shear deformation generated in the structure, the lower beam and the beam move relative to each other in the horizontal direction.

  Therefore, the joint between the beam and the upper end of the damper member moves away from the joint between the lower beam and the lower end of the damper member.

  And since a damper member is extended with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  Further, the column extends upward by bending deformation generated in the structure. Here, the upper end portion of the rigid member is coupled to the column, and the lower end portion is coupled to the upper end portion of the damper member, so that the amount of elongation deformation of the rigid member is small. Therefore, the upper end portion of the damper member is pulled upward by the column extending upward.

  And since a damper member is extended with the raising of the upper end part of this damper member, a damping effect is exhibited and the bending deformation generate | occur | produced in a structure can be suppressed.

  Further, the damper member extends due to the shear deformation generated in the structure, and the damper member also extends due to the bending deformation generated in the structure. Therefore, the deformation direction of the damper member is the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  Next, the action and effect of the damping mechanism arranged on the right side of the structure when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure will be described. .

  Due to the shear deformation generated in the structure, the lower beam and the beam move relative to each other in the horizontal direction.

  Therefore, the coupling portion between the beam and the upper end portion of the damper member moves in the approaching direction with respect to the coupling portion between the lower beam and the lower end portion of the damper member.

  And since a damper member contracts with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  Further, the column shrinks downward due to bending deformation generated in the structure. Here, the upper end portion of the rigid member is coupled to the column, and the lower end portion is coupled to the upper end portion of the damper member, so that the amount of contraction deformation of the rigid member is small. Therefore, the upper end portion of the damper member is pushed downward by shrinking the column downward.

  Since the damper member contracts as the upper end of the damper member is pushed down, a damping effect can be exerted and bending deformation occurring in the structure can be suppressed.

  Further, the damper member contracts due to the shear deformation generated in the structure, and the damper member contracts also due to the bending deformation generated in the structure, so that the deformation direction of the damper member becomes the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  By these, the shear deformation and bending deformation which generate | occur | produce in a structure can be suppressed, and the effect of the damper member which suppresses the shear deformation generate | occur | produced in a structure is not reduced by bending deformation. Moreover, the structural safety | security of a structure improves by suppressing the bending deformation of the structure which was difficult conventionally.

  When a horizontal force from right to left is applied to the structure, the case described above (when a horizontal force from left to right is applied to the structure) is applied by the vibration control mechanism arranged on the right side of the structure. ), The same operation and effect as the vibration damping mechanism arranged on the left side of the structure can be obtained. In the case where a horizontal force is applied), the same operation and effect as those of the vibration damping mechanism arranged on the right side of the structure can be obtained.

  Moreover, since the column installed upright on the outer periphery of the structure or in the vicinity of the outer periphery has a large amount of deformation in the axial direction of the column when bending deformation occurs in the structure, the damper member can be greatly deformed. Therefore, the bending deformation which generate | occur | produces in a structure can be suppressed effectively.

  In addition, since the vibration damping structure can be constructed simply by providing a rigid member and a damper member in the existing structure, the repair work can be easily performed. In the case of a new construction, the cost can be reduced.

  According to a third aspect of the present invention, the support member is a column erected on or near the outer periphery of the structure, and the intermediate member is provided between the upper beam and the lower beam. It is a beam that is joined to the column and protrudes to the outside of the structure, and the damper member has an upper end coupled at a joint portion between the column and the upper beam, and is directed outward and downward from the structure. The lower end of the rigid member is disposed obliquely toward the outer upper side of the structure, and the lower end of the damper member is connected to the lower end of the rigid member. The upper end part of the member and the beam are combined.

In the invention according to claim 3, the support member is a column erected on or near the outer periphery of the structure,
The intermediate member is a beam provided between the upper beam and the lower beam. The beam is joined to the column and protrudes outside the structure.

  The upper end portion of the damper member is coupled by a joint portion between the column and the upper beam. Further, the damper member is disposed obliquely toward the outside lower side of the structure.

  The lower end portion of the rigid member is joined by a joint portion between the column and the lower beam. Moreover, the rigid member is diagonally arranged toward the outer upper side of the structure.

  Further, the lower end portion of the damper member, the upper end portion of the rigid member, and the beam are coupled.

  First, the action and effect of the vibration control mechanism arranged on the left side of the structure when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur at the same time will be described.

  The upper beam and the beam move relative to each other in the horizontal direction due to the shear deformation generated in the structure.

  Therefore, the joint between the upper beam and the upper end of the damper member moves away from the joint between the beam and the lower end of the damper member.

  And since a damper member is extended with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  Further, since the column extends upward due to the bending deformation generated in the structure, the coupling portion between the column and the upper end portion of the damper member moves away from the coupling portion between the beam and the lower end portion of the damper member. .

  And since a damper member is extended with this movement, a damping effect is exhibited and the bending deformation which generate | occur | produces in a structure can be suppressed.

  The column extends upward due to the bending deformation, and the joint between the upper beam and the upper end of the damper member moves upward. At this time, the portion of the beam that protrudes outside the structure rotates clockwise around the joint between the beam and the column, and with this, the joint between the beam and the lower end of the damper member is Try to move upward. However, the rigid member has an upper end portion coupled to the lower end portion of the damper member and the beam, and a lower end portion coupled to the column, and the amount of elongation deformation of the rigid member is small. Therefore, the upward movement of the joint portion between the beam and the lower end portion of the damper member is prevented. Therefore, the damper member extends sufficiently.

  Further, the damper member extends due to the shear deformation generated in the structure, and the damper member also extends due to the bending deformation generated in the structure. Therefore, the deformation direction of the damper member is the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  Next, the action and effect of the damping mechanism arranged on the right side of the structure when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure will be described. .

  The upper beam and the beam move relative to each other in the horizontal direction due to the shear deformation generated in the structure.

  Therefore, the connecting portion between the upper beam and the upper end portion of the damper member moves toward the connecting portion between the beam and the lower end portion of the damper member.

  And since a damper member contracts with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  In addition, since the column contracts downward due to bending deformation generated in the structure, the coupling portion between the column and the upper end portion of the damper member moves in a direction closer to the coupling portion between the beam and the lower end portion of the damper member. .

  And since a damper member shrinks with this movement, a damping effect is exhibited and the bending deformation which generate | occur | produces in a structure can be suppressed.

  The column contracts downward due to the bending deformation, and the joint between the upper beam and the upper end of the damper member moves downward. At this time, the portion of the beam that protrudes outside the structure rotates clockwise around the joint between the beam and the column, and with this, the joint between the beam and the lower end of the damper member is Try to move down. However, the rigid member has an upper end portion coupled to the lower end portion of the damper member and the beam, and a lower end portion coupled to the column, and the amount of contraction deformation of the rigid member is small. Therefore, the downward movement of the joint portion between the beam and the lower end portion of the damper member is prevented. Therefore, the damper member is sufficiently contracted.

  Further, the damper member contracts due to the shear deformation generated in the structure, and the damper member contracts also due to the bending deformation generated in the structure, so that the deformation direction of the damper member becomes the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  By these, the shear deformation and bending deformation which generate | occur | produce in a structure can be suppressed, and the effect of the damper member which suppresses the shear deformation generate | occur | produced in a structure is not reduced by bending deformation. Moreover, the structural safety | security of a structure improves by suppressing the bending deformation of the structure which was difficult conventionally.

  When a horizontal force from right to left is applied to the structure, the case described above (when a horizontal force from left to right is applied to the structure) is applied by the vibration control mechanism arranged on the right side of the structure. ), The same operation and effect as the vibration damping mechanism arranged on the left side of the structure can be obtained. In the case where a horizontal force is applied), the same operation and effect as those of the vibration damping mechanism arranged on the right side of the structure can be obtained.

  Moreover, since the column installed upright on the outer periphery of the structure or in the vicinity of the outer periphery has a large amount of deformation in the axial direction of the column when bending deformation occurs in the structure, the damper member can be greatly deformed. Therefore, the bending deformation which generate | occur | produces in a structure can be suppressed effectively.

  In addition, since the vibration damping structure can be constructed simply by providing a rigid member and a damper member in the existing structure, the repair work can be easily performed. In the case of a new construction, the cost can be reduced.

  According to a fourth aspect of the present invention, the support member is a core wall built inside the structure, or a pillar that follows the core wall, and the intermediate member includes the upper beam and the lower beam. The damper member is provided between the core wall or a column joined to the core wall, and the damper member has an upper end at the junction between the core wall or the column following the core wall and the upper beam. The rigid members are arranged obliquely downward and on the side away from the core wall, and the rigid member is joined at the lower end at the joint between the core wall or the pillar that follows the core wall and the lower beam. And arranged obliquely upward on the side away from the core wall, wherein the lower end portion of the damper member, the upper end portion of the rigid member, and the beam are combined.

  In the invention according to claim 4, the support member is a core wall built inside the structure or a pillar following the core wall, and the intermediate member is a beam provided between the upper beam and the lower beam. Further, the beam is joined to the core wall or a column that follows the core wall.

  The upper end portion of the damper member is coupled to the core wall or a column that follows the core wall and a joint portion between the upper beam. In addition, the damper member is disposed obliquely toward the lower side on the side away from the core wall.

  The lower end portion of the rigid member is coupled to the core wall or a column that follows the core wall and a joint portion between the lower beam. Moreover, the rigid member is diagonally arranged toward the upper side on the side away from the core wall.

  Further, the lower end portion of the damper member, the upper end portion of the rigid member, and the beam are coupled.

  First, the action and effect of the vibration damping mechanism arranged on the left side of the core wall when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure will be described.

  The upper beam and the beam move relative to each other in the horizontal direction due to the shear deformation generated in the structure.

  Therefore, the joint between the upper beam and the upper end of the damper member moves away from the joint between the beam and the lower end of the damper member.

  And since a damper member is extended with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  In addition, due to bending deformation occurring in the structure, the left edge of the core wall or a pillar that follows the core wall (hereinafter, the core wall left edge and the pillar that follows the core wall are collectively referred to as a first core member) Is extended upward, the connecting portion between the first core member and the upper end portion of the damper member moves away from the connecting portion between the beam and the lower end portion of the damper member.

  And since a damper member is extended with the movement of this coupling | bond part, a damping effect is exhibited and the bending deformation generate | occur | produced in a structure can be suppressed.

  The first core member extends upward by bending deformation, and the joint between the upper beam and the upper end of the damper member moves upward. At this time, the beam rotates clockwise around the joint between the beam and the first core member as a center of rotation, and accordingly, the joint between the beam and the lower end of the damper member tends to move upward. . However, the rigid member has an upper end portion coupled to the lower end portion of the damper member and the beam, and a lower end portion coupled to the first core member, and the amount of elongation deformation of the rigid member is small. Therefore, the upward movement of the joint portion between the beam and the lower end portion of the damper member is prevented. Therefore, the damper member extends sufficiently.

  Further, the damper member extends due to the shear deformation generated in the structure, and the damper member also extends due to the bending deformation generated in the structure. Therefore, the deformation direction of the damper member is the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  Next, the action and effect of the damping mechanism arranged on the right side of the core wall when a horizontal force from the left to the right is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure will be described. .

  The upper beam and the beam move relative to each other in the horizontal direction due to the shear deformation generated in the structure.

  Therefore, the connecting portion between the upper beam and the upper end portion of the damper member moves toward the connecting portion between the beam and the lower end portion of the damper member.

  And since a damper member contracts with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  In addition, due to bending deformation occurring in the structure, the right edge of the core wall or a column that follows the core wall (hereinafter, the core wall right edge and the column that follows the core wall are collectively referred to as a second core member) Is contracted downward, the connecting portion between the second core member and the upper end portion of the damper member moves in the approaching direction with respect to the connecting portion between the beam and the lower end portion of the damper member.

  And since a damper member shrinks with the movement of this coupling | bond part, a damping effect is exhibited and the bending deformation generate | occur | produced in a structure can be suppressed.

  The second core member contracts downward due to the bending deformation, and the joint between the upper beam and the upper end of the damper member moves downward. At this time, the beam rotates clockwise with the joint between the beam and the second core member as the center of rotation, and accordingly, the joint between the beam and the lower end of the damper member tends to move downward. . However, the rigid member has an upper end portion coupled to the lower end portion of the damper member and the beam and a lower end portion coupled to the second core member, and the amount of contraction deformation of the rigid member is small. Therefore, the downward movement of the joint portion between the beam and the lower end portion of the damper member is prevented. Therefore, the damper member is sufficiently contracted.

  Further, the damper member contracts due to the shear deformation generated in the structure, and the damper member contracts also due to the bending deformation generated in the structure, so that the deformation direction of the damper member becomes the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  By these, the shear deformation and bending deformation which generate | occur | produce in a structure can be suppressed, and the effect of the damper member which suppresses the shear deformation generate | occur | produced in a structure is not reduced by bending deformation. Moreover, the structural safety | security of a structure improves by suppressing the bending deformation of the structure which was difficult conventionally.

  When a horizontal force from right to left is applied to the structure, the case described above (when a horizontal force from left to right is applied to the structure) is applied by the damping mechanism arranged on the right side of the core wall. ), The same operation and effect as the vibration damping mechanism arranged on the left side of the core wall can be obtained. In the case where a horizontal force is applied), the same action and effect as the vibration damping mechanism arranged on the right side of the core wall can be obtained.

  Moreover, since the amount of deformation in the length direction when the core wall edge or the column that follows the core wall undergoes bending deformation in the structure is large, the damper member can be greatly deformed. Therefore, the bending deformation which generate | occur | produces in a structure can be suppressed effectively.

  In addition, since the vibration damping structure can be constructed simply by providing a rigid member and a damper member in the existing structure, the repair work can be easily performed. In the case of a new construction, the cost can be reduced.

  According to a fifth aspect of the present invention, in the vibration damping structure in which the vibration damping mechanism is arranged in the hierarchy of the structure, an intermediate member provided between the upper floor beam and the lower floor beam of the hierarchy, A support member that is erected and to which the upper floor beam and the lower floor beam are joined, and wherein the vibration control mechanism is between the upper floor beam and the intermediate member, or the lower floor beam and the A damper member disposed between the intermediate member and deformed when shear deformation occurs in the structure; and between the upper floor beam and the intermediate member where the damper member is not disposed; A rigid member disposed between the floor beam and the intermediate member and connected to an end of the damper member to transmit axial deformation of the support member to the damper member, and shearing the structure The direction of deformation of the damper member when deformation occurs, and the structure is bent. Deformation the support member is generated is characterized in that the deformation direction of the damper member is disposed the rigid member to be the same when deformed axially.

  In the invention described in claim 5, the vibration damping structure is constructed by arranging the vibration damping mechanism in the hierarchy of the structure.

  The vibration control structure includes an upper floor beam in the hierarchy, a lower floor beam in the hierarchy, an intermediate member provided between the upper floor beam and the lower floor beam, and a support member standing up and down. Moreover, the upper floor beam and the lower floor beam are joined to the support member.

  The vibration damping mechanism includes a damper member and a rigid member.

  The damper member is disposed between the upper floor beam and the intermediate member, or between the lower floor beam and the intermediate member. The damper member is deformed when shear deformation occurs in the structure.

  The rigid member is disposed between the upper floor beam and the intermediate member, or between the lower floor beam and the intermediate member, where the damper member is not disposed. The rigid member is connected to the end of the damper member and transmits the axial deformation of the support member to the damper member.

  Furthermore, in the rigid member, the deformation direction of the damper member when shear deformation occurs in the structure is the same as the deformation direction of the damper member when bending deformation occurs in the structure and the support member deforms in the axial direction. It is arranged to be.

  Therefore, when a horizontal force is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure, the upper floor beam and the intermediate member, and the lower floor beam and the intermediate member are first subjected to shear generated in the structure. Relative movement in the horizontal direction by deformation.

  At this time, the damper member arranged between the upper floor beam and the intermediate member or between the lower floor beam and the intermediate member is deformed along with this relative movement, so that it exhibits a damping effect and is generated in the structure. Shearing deformation can be suppressed.

  Further, the support member is deformed in the axial direction when bending deformation occurs in the structure.

  At this time, the damper member is not disposed, the rigid member disposed between the upper floor beam and the intermediate member, or between the lower floor beam and the intermediate member and coupled to the end of the damper member, thereby supporting the member. Since the axial deformation is transmitted to the damper member, the damper member is deformed and exhibits a damping effect. Therefore, bending deformation generated in the structure can be suppressed.

  Also, the deformation direction of the damper member when shear deformation occurs in the structure is the same as the deformation direction of the damper member when bending deformation occurs in the structure and the support member deforms in the axial direction.

  By these, the shear deformation and bending deformation which generate | occur | produce in a structure can be suppressed, and the effect of the damper member which suppresses the shear deformation generate | occur | produced in a structure is not reduced by bending deformation. Moreover, the structural safety | security of a structure improves by suppressing the bending deformation of the structure which was difficult conventionally.

  According to a sixth aspect of the present invention, the support member is a column erected on or near the outer periphery of the structure, and the intermediate member is provided between the upper floor beam and the lower floor beam. The damper member is disposed obliquely toward the upper inside of the structure with a lower end portion joined at a joint portion between the column and the lower floor beam, and the rigid member is An upper end portion is coupled at a joint portion between the column and the upper floor beam and is disposed obliquely toward the inner lower side of the structure, and the upper end portion of the damper member, the lower end portion of the rigid member, and the connecting beam It is characterized by being connected.

  In the sixth aspect of the invention, the support member is a column erected on or near the outer periphery of the structure, and the intermediate member is a connecting beam provided between the upper floor beam and the lower floor beam.

  The lower end portion of the damper member is joined by a joint portion between the column and the lower floor beam. In addition, the damper member is disposed obliquely toward the inside upper side of the structure.

  The upper end portion of the rigid member is joined at the joint portion between the column and the upper floor beam. Moreover, the rigid member is diagonally arranged toward the inner lower side of the structure.

  Furthermore, the upper end part of a damper member, the lower end part of a rigid member, and the connecting beam are couple | bonded.

  First, the action and effect of the vibration control mechanism arranged on the left side of the structure when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur at the same time will be described.

  Due to the shear deformation generated in the structure, the lower and upper floor beams move relative to each other in the horizontal direction. At this time, since the stable trapezoid is formed by the rigid member, the connecting beam, and the upper floor beam, the connecting beam and the lower floor beam connected to the upper floor beam via the rigid member also move relative to each other in the horizontal direction.

  Therefore, the connecting portion between the connecting beam and the upper end portion of the damper member moves away from the connecting portion between the lower floor beam and the lower end portion of the damper member.

  And since a damper member is extended with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  Further, the column extends upward by bending deformation generated in the structure. Here, the rigid member has an upper end coupled to the column and a lower end coupled to the upper end of the damper member, and the amount of elongation deformation of the rigid member is small. Further, a stable trapezoid is formed by the rigid member, the connecting beam, and the upper floor beam. Therefore, the upper end portion of the damper member is pulled upward by the column extending upward.

  And since a damper member is extended with the raising of the upper end part of this damper member, a damping effect is exhibited and the bending deformation generate | occur | produced in a structure can be suppressed.

  Further, the damper member extends due to the shear deformation generated in the structure, and the damper member also extends due to the bending deformation generated in the structure. Therefore, the deformation direction of the damper member is the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  Next, the action and effect of the damping mechanism arranged on the right side of the structure when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure will be described. .

  Due to the shear deformation generated in the structure, the lower and upper floor beams move relative to each other in the horizontal direction. At this time, since the stable trapezoid is formed by the rigid member, the connecting beam, and the upper floor beam, the connecting beam and the lower floor beam connected to the upper floor beam via the rigid member also move relative to each other in the horizontal direction.

  Therefore, the connecting portion between the connecting beam and the upper end portion of the damper member moves toward the connecting portion between the lower floor beam and the lower end portion of the damper member.

  And since a damper member contracts with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  Further, the column shrinks downward due to bending deformation generated in the structure. Here, the rigid member has an upper end coupled to the column and a lower end coupled to the upper end of the damper member, and the amount of contraction deformation of the rigid member is small. Further, a stable trapezoid is formed by the rigid member, the connecting beam, and the upper floor beam. Therefore, the upper end portion of the damper member is pushed downward by shrinking the column downward.

  Since the damper member contracts as the upper end of the damper member is pushed down, a damping effect can be exerted and bending deformation occurring in the structure can be suppressed.

  Further, the damper member contracts due to the shear deformation generated in the structure, and the damper member contracts also due to the bending deformation generated in the structure, so that the deformation direction of the damper member becomes the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  By these, the shear deformation and bending deformation which generate | occur | produce in a structure can be suppressed, and the effect of the damper member which suppresses the shear deformation generate | occur | produced in a structure is not reduced by bending deformation. Moreover, the structural safety | security of a structure improves by suppressing the bending deformation of the structure which was difficult conventionally.

  When a horizontal force from right to left is applied to the structure, the case described above (when a horizontal force from left to right is applied to the structure) is applied by the vibration control mechanism arranged on the right side of the structure. ), The same operation and effect as the vibration damping mechanism arranged on the left side of the structure can be obtained. In the case where a horizontal force is applied), the same operation and effect as those of the vibration damping mechanism arranged on the right side of the structure can be obtained.

  Moreover, since the column installed upright on the outer periphery of the structure or in the vicinity of the outer periphery has a large amount of deformation in the axial direction of the column when bending deformation occurs in the structure, the damper member can be greatly deformed. Therefore, the bending deformation which generate | occur | produces in a structure can be suppressed effectively.

  According to a seventh aspect of the present invention, the support member is a column erected on or near the outer periphery of the structure, and the intermediate member is provided between the upper floor beam and the lower floor beam. A brace that is disposed obliquely toward the outer lower side of the structure, the upper end of which is joined to the joint between the inner pillar standing on the inside of the structure and the upper floor beam with respect to the pillar. And the damper member is disposed obliquely toward the inside upper side of the structure with a lower end coupled at a joint portion between the column and the lower floor beam, and the rigid member includes the column and the The upper end is joined at the joint with the upper floor beam and is arranged obliquely toward the inner lower side of the structure, and the upper end of the damper member, the lower end of the rigid member, and the brace member are joined. It is characterized by being.

  In the invention according to claim 7, the support member is a column erected on or near the outer periphery of the structure, and the intermediate member is a brace member provided between the upper floor beam and the lower floor beam. The upper end portion of the brace member is coupled to the joint portion between the inner column and the upper floor beam that are erected on the inner side of the structure than the column. Moreover, the brace member is diagonally arranged toward the outer lower side of the structure.

  The lower end portion of the damper member is joined by a joint portion between the column and the lower floor beam. In addition, the damper member is disposed obliquely toward the inside upper side of the structure.

  The upper end portion of the rigid member is joined at the joint portion between the column and the upper floor beam. Moreover, the rigid member is diagonally arranged toward the inner lower side of the structure.

  Furthermore, the upper end part of a damper member, the lower end part of a rigid member, and the brace member are couple | bonded.

  First, the action and effect of the vibration control mechanism arranged on the left side of the structure when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur at the same time will be described.

  Due to the shear deformation generated in the structure, the lower and upper floor beams move relative to each other in the horizontal direction. At this time, since a stable triangle is formed by the rigid member, the brace member, and the upper floor beam, the brace member and the lower floor beam in which the upper end portion is coupled to the joint portion between the inner column and the upper floor beam are also in the horizontal direction. Move relative to.

  Therefore, the connecting portion between the brace member and the upper end portion of the damper member moves away from the connecting portion between the lower floor beam and the lower end portion of the damper member.

  And since a damper member is extended with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  Further, the column extends upward by bending deformation generated in the structure. Here, the rigid member has an upper end coupled to the column and a lower end coupled to the upper end of the damper member, and the amount of elongation deformation of the rigid member is small. A stable triangle is formed by the rigid member, the brace member, and the upper floor beam. Therefore, the upper end portion of the damper member is pulled upward by the column extending upward.

  And since a damper member is extended with the raising of the upper end part of this damper member, a damping effect is exhibited and the bending deformation generate | occur | produced in a structure can be suppressed.

  Further, the damper member extends due to the shear deformation generated in the structure, and the damper member also extends due to the bending deformation generated in the structure. Therefore, the deformation direction of the damper member is the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  Next, the action and effect of the damping mechanism arranged on the right side of the structure when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure will be described. .

  Due to the shear deformation generated in the structure, the lower and upper floor beams move relative to each other in the horizontal direction. At this time, since a stable triangle is formed by the rigid member, the brace member, and the upper floor beam, the brace member and the lower floor beam in which the upper end portion is coupled to the joint portion between the inner column and the upper floor beam are also in the horizontal direction. Move relative to.

  Therefore, the connecting portion between the brace member and the upper end portion of the damper member moves toward the connecting portion between the lower floor beam and the lower end portion of the damper member.

  And since a damper member contracts with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  Further, the column shrinks downward due to bending deformation generated in the structure. Here, the rigid member has an upper end coupled to the column and a lower end coupled to the upper end of the damper member, and the amount of contraction deformation of the rigid member is small. A stable triangle is formed by the rigid member, the brace member, and the upper floor beam. Therefore, the upper end portion of the damper member is pushed downward by shrinking the column downward.

  Since the damper member contracts as the upper end of the damper member is pushed down, a damping effect can be exerted and bending deformation occurring in the structure can be suppressed.

  Further, the damper member contracts due to the shear deformation generated in the structure, and the damper member contracts also due to the bending deformation generated in the structure, so that the deformation direction of the damper member becomes the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  By these, the shear deformation and bending deformation which generate | occur | produce in a structure can be suppressed, and the effect which suppresses the shear deformation generate | occur | produced in a structure is not reduced by bending deformation. Moreover, the structural safety | security of a structure improves by suppressing the bending deformation of the structure which was difficult conventionally.

  When a horizontal force from right to left is applied to the structure, the case described above (when a horizontal force from left to right is applied to the structure) is applied by the vibration control mechanism arranged on the right side of the structure. ), The same operation and effect as the vibration damping mechanism arranged on the left side of the structure can be obtained. In the case where a horizontal force is applied), the same operation and effect as those of the vibration damping mechanism arranged on the right side of the structure can be obtained.

  Moreover, since the column installed upright on the outer periphery of the structure or in the vicinity of the outer periphery has a large amount of deformation in the axial direction of the column when bending deformation occurs in the structure, the damper member can be greatly deformed. Therefore, the bending deformation which generate | occur | produces in a structure can be suppressed effectively.

  According to an eighth aspect of the present invention, the support member is a core wall built inside the structure or a pillar that follows the core wall, and the intermediate member includes the upper floor beam and the lower floor beam. The lower end is joined to the joint between the outer pillar and the lower floor beam that is provided between the outer column and the outer periphery of the structure and obliquely toward the upper inside of the structure. The brace member is disposed, and the damper member faces the lower side of the core wall or the side that is separated from the core wall by joining the upper end at the joint portion between the core wall or the pillar that follows the core wall and the upper floor beam. Arranged diagonally, the rigid member is arranged obliquely upward on the side away from the core wall by connecting the lower end of the core wall or a joint that follows the core wall and the lower floor beam. A lower end portion of the damper member, an upper end portion of the rigid member, and the brace portion. Bets are characterized by being coupled.

  In the invention according to claim 8, the support member is a core wall built inside the structure or a pillar following the core wall, and the intermediate member is a brace member provided between the upper floor beam and the lower floor beam. It is said.

  A lower end portion of the brace member is coupled to a joint portion between an outer column and a lower floor beam that are erected on or near the outer periphery of the structure. Moreover, the brace member is diagonally arranged toward the inner upper side of the structure.

  The upper end portion of the damper member is coupled by a joint portion between the core wall or a pillar that follows the core wall and the upper floor beam. In addition, the damper member is disposed obliquely toward the lower side on the side away from the core wall.

  The lower end portion of the rigid member is coupled by a joint portion between the core wall or a column following the core wall and the lower floor beam. Moreover, the rigid member is diagonally arranged toward the upper side on the side away from the core wall.

  Furthermore, the lower end part of a damper member, the upper end part of a rigid member, and the brace member are couple | bonded.

  First, the action and effect of the vibration damping mechanism arranged on the left side of the core wall when a horizontal force from left to right is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure will be described.

  Due to the shear deformation generated in the structure, the lower and upper floor beams move relative to each other in the horizontal direction. At this time, since a stable triangle is formed by the rigid member, the brace member, and the lower floor beam, the brace member and the upper floor beam in which the lower end portion is coupled to the joint portion between the outer column and the lower floor beam are also in the horizontal direction. Move relative to.

  Therefore, the connecting portion between the brace member and the lower end portion of the damper member moves away from the connecting portion between the upper floor beam and the upper end portion of the damper member.

  And since a damper member is extended with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  In addition, due to bending deformation occurring in the structure, the left edge of the core wall or a pillar that follows the core wall (hereinafter, the core wall left edge and the pillar that follows the core wall are collectively referred to as a first core member) Extends upward. Here, the rigid member has a lower end portion coupled to the first core member and an upper end portion coupled to the lower end portion of the damper member, and the amount of elongation deformation of the rigid member is small. Further, a stable triangle is formed by the rigid member, the brace member, and the lower floor beam. Therefore, the upper end portion of the damper member is pulled upward by the first core member extending upward.

  And since a damper member is extended with the raising of the upper end part of this damper member, a damping effect is exhibited and the bending deformation generate | occur | produced in a structure can be suppressed.

  Further, the damper member extends due to the shear deformation generated in the structure, and the damper member also extends due to the bending deformation generated in the structure. Therefore, the deformation direction of the damper member is the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  Next, the action and effect of the damping mechanism arranged on the right side of the core wall when a horizontal force from the left to the right is applied to the structure and shear deformation and bending deformation occur simultaneously in the structure will be described. .

  Due to the shear deformation generated in the structure, the lower and upper floor beams move relative to each other in the horizontal direction. At this time, since a stable triangle is formed by the rigid member, the brace member, and the lower floor beam, the brace member and the upper floor beam in which the lower end portion is coupled to the joint portion between the outer column and the lower floor beam are also in the horizontal direction. Move relative to.

  Therefore, the connecting portion between the brace member and the lower end portion of the damper member moves toward the connecting portion between the upper floor beam and the upper end portion of the damper member.

  And since a damper member contracts with the movement of this coupling | bond part, a damping effect is exhibited and the shear deformation generate | occur | produced in a structure can be suppressed.

  In addition, due to bending deformation occurring in the structure, the right edge of the core wall or a column that follows the core wall (hereinafter, the core wall right edge and the column that follows the core wall are collectively referred to as a second core member) Shrinks downward.

  Here, the rigid member has a lower end portion coupled to the second core member and an upper end portion coupled to the lower end portion of the damper member, and the amount of contraction deformation of the rigid member is small. Further, a stable triangle is formed by the rigid member, the brace member, and the lower floor beam. Therefore, the upper end portion of the damper member is pushed downward by shrinking the column downward.

  Since the damper member contracts as the upper end of the damper member is pushed down, a damping effect can be exerted and bending deformation occurring in the structure can be suppressed.

  Further, the damper member contracts due to the shear deformation generated in the structure, and the damper member contracts also due to the bending deformation generated in the structure, so that the deformation direction of the damper member becomes the same. Therefore, the deformation of the damper member due to the bending deformation generated in the structure does not reduce the amount of deformation of the damper member due to the shear deformation generated in the structure.

  By these, the shear deformation and bending deformation which generate | occur | produce in a structure can be suppressed, and the effect which suppresses the shear deformation generate | occur | produced in a structure is not reduced by bending deformation. Moreover, the structural safety | security of a structure improves by suppressing the bending deformation of the structure which was difficult conventionally.

  When a horizontal force from right to left is applied to the structure, the case described above (when a horizontal force from left to right is applied to the structure) is applied by the damping mechanism arranged on the right side of the core wall. ), The same operation and effect as the vibration damping mechanism arranged on the left side of the core wall can be obtained. In the case where a horizontal force is applied), the same action and effect as the vibration damping mechanism arranged on the right side of the core wall can be obtained.

  Moreover, since the amount of deformation in the length direction when the core wall edge or the column that follows the core wall undergoes bending deformation in the structure is large, the damper member can be greatly deformed. Therefore, the bending deformation which generate | occur | produces in a structure can be suppressed effectively.

  Since this invention set it as the said structure, the shear deformation and bending deformation which generate | occur | produce in a structure are suppressed, and the effect which suppresses shear deformation is not reduced by bending deformation.

  Embodiments of the present invention will be described with reference to the drawings. In the present embodiment, an example of an S structure building will be described. However, various structures such as an SRC structure and an RC structure can be applied to new and renovated buildings.

  First, the vibration damping structure 10 according to the first embodiment of the present invention will be described.

  FIG. 1 shows a vibration damping structure 10 of the first embodiment. The damping structure 10 is constructed by arranging a plurality of damping mechanisms 14 in an S-structure building 12 as a structure built on the ground 20.

  As shown in FIG. 1, the vibration control mechanism 14 is arranged on all floors from the left and right first floors of the building 12 to the rooftop floor.

  As shown in FIG. 2, the vibration damping mechanism 14 disposed on the left side of the building 12 includes a damper member 16 and a rigid member 18 and is disposed across two layers. That is, as shown in FIG. 1, when the number of floors of the building 12 is n, the vibration control mechanism 14 is arranged across two layers from the nth floor to the (n + 2) th floor.

  For example, the vibration damping mechanism 14 is arranged from the 17th floor to the 19th floor, and the vibration damping mechanism 14 disposed above the floor extends from the 18th floor to the 20th floor. The following description will be made on one vibration control mechanism 14 arranged from the nth floor to the (n + 2) th floor.

  As shown in FIG. 2, the damping structure 10 includes an upper beam 22 provided at the uppermost part of the two layers, a lower beam 24 provided at the lowermost part of the two layers, an upper beam 22 and a lower beam 24. It has a beam 26 as an intermediate member provided between them, and a column 28 as a support member standing up and down.

  The column 28 is erected on the outer periphery of the building 12, and the upper beam 22 and the lower beam 24 are joined to each other. The beam 26 is joined to the column 28.

  The lower end portion of the damper member 16 is pin-coupled by a joint portion (joint portion 30) between the column 28 and the lower beam 24. Further, the damper member 16 is disposed obliquely toward the upper inside of the building 12.

  The upper end portion of the rigid member 18 is pin-coupled by a joint portion (joint portion 32) between the column 28 and the upper beam 22. Further, the rigid member 18 is disposed obliquely toward the inner lower side of the building 12.

  Furthermore, the upper end portion of the damper member 16 and the lower end portion of the rigid member 18 are respectively pin-coupled to the beam 26 by the coupling portion 34. That is, the damper member 16 is disposed between the lower beam 24 and the beam 26, and the rigid member 18 is disposed between the upper beam 22 and the beam 26 where the damper member 16 is not disposed.

  Further, with these structures, the rigid member 18 can transmit the axial deformation of the column 28 to the damper member 16.

  FIG. 4 shows the vibration control mechanism 14 arranged on the right side of the building 12. Since the vibration control mechanism 14 arranged on the left side of the building 12 and the vibration control mechanism 14 arranged on the right side of the building 12 have a line-symmetric configuration with respect to the central axis of the building 12, the right side of the building 12 The description of the vibration control mechanism 14 arranged in the above will be omitted. The vibration control mechanism 14 disposed on the right side of the building 12 is also disposed from the nth floor to the (n + 2) th floor.

  Next, the operation and effect of the vibration damping structure 10 according to the first embodiment of the present invention will be described.

  First, as shown in FIG. 3, when a horizontal force P from left to right is applied to the building 12 and shear deformation and bending deformation occur simultaneously in the building 12, a vibration damping mechanism disposed on the left side of the building 12. 14 will be described.

  The lower beam 24 and the beam 26 relatively move in the horizontal direction due to the shear deformation generated in the building 12.

  Therefore, the coupling portion 34 between the beam 26 and the upper end portion of the damper member 16 moves away from the coupling portion 30 between the lower beam 24 and the lower end portion of the damper member 16.

  Since the damper member 16 extends (arrow 38) with the movement of the coupling portion 34 (arrow 36), a damping effect can be exerted and shear deformation occurring in the building 12 can be suppressed.

  Further, the column 28 extends upward by bending deformation generated in the building 12. Here, the rigid member 18 has an upper end coupled to the column 28 and a lower end coupled to the upper end of the damper member 16, and the amount of expansion deformation of the rigid member 18 is small. Therefore, the upper end of the damper member 16 is pulled upward by the pillar 28 extending upward (arrow 42).

  Since the damper member 16 extends (arrow 40) as the upper end of the damper member 16 is pulled up, the damping effect can be exerted and bending deformation occurring in the building 12 can be suppressed.

  Further, the damper member 16 extends due to the shear deformation generated in the building 12 (arrow 38), and the damper member 16 extends also due to the bending deformation generated in the building 12 (arrow 40), so that the deformation direction of the damper member 16 becomes the same. . Therefore, the deformation of the damper member 16 due to the bending deformation generated in the building 12 does not reduce the deformation amount of the damper member 16 due to the shear deformation generated in the building 12.

  Next, when a horizontal force from left to right is applied to the building 12 and shear deformation and bending deformation occur simultaneously in the building 12, the action of the vibration control mechanism 14 shown in FIG. The effects will be described.

  The lower beam 24 and the beam 26 relatively move in the horizontal direction due to the shear deformation generated in the building 12.

  Therefore, the coupling portion 34 between the beam 26 and the upper end portion of the damper member 16 moves in the approaching direction with respect to the coupling portion 30 between the lower beam 24 and the lower end portion of the damper member 16.

  And since the damper member 16 shrinks with the movement of this coupling | bond part 34, a damping effect is exhibited and the shear deformation | transformation which generate | occur | produces in the building 12 can be suppressed.

  Further, the column 28 contracts downward due to bending deformation generated in the building 12. Here, the rigid member 18 has an upper end coupled to the column 28 and a lower end coupled to the upper end of the damper member 16, and the amount of contraction deformation of the rigid member 18 is small. Therefore, the upper end portion of the damper member 16 is pushed downward by shrinking the column 28 downward.

  Since the damper member 16 contracts as the upper end of the damper member 16 is pushed down, a damping effect can be exerted and bending deformation occurring in the building 12 can be suppressed.

  Further, the damper member 16 contracts due to the shear deformation generated in the building 12, and the damper member 16 contracts also due to the bending deformation generated in the building 12. Therefore, the deformation direction of the damper member 16 is the same. Therefore, the deformation of the damper member 16 due to the bending deformation generated in the building 12 does not reduce the deformation amount of the damper member 16 due to the shear deformation generated in the building 12.

  By these, the shear deformation and bending deformation which generate | occur | produce in the building 12 can be suppressed, and the effect of the damper member 16 which suppresses the shear deformation generated in the building 12 is not reduced by bending deformation. Moreover, the structural safety | security of the building 12 improves by suppressing the bending deformation of the building 12 which was difficult conventionally.

  When a horizontal force from the right to the left is applied to the building 12, the case described above (the horizontal force P from the left to the right is applied to the building 12) by the vibration control mechanism 14 disposed on the right side of the building 12. The same action and effect as the vibration damping mechanism 14 disposed on the left side of the building 12 is obtained, and the vibration damping mechanism 14 disposed on the left side of the building 12 causes the case described above (building 12). When a horizontal force P from left to right is applied), the same operation and effect as the vibration damping mechanism 14 arranged on the right side of the building 12 can be obtained.

  Moreover, since the damping structure 10 of 1st Embodiment can be constructed | assembled only by providing the rigid member 18 and the damper member 16 in the existing building 12, renovation work can be performed easily. In the case of a new construction, the cost can be reduced.

  Moreover, since the column 28 erected on the outer periphery of the building 12 has a large amount of axial deformation of the column 28 when bending deformation occurs in the building 12, the damper member 16 can be largely deformed. Therefore, the bending deformation which generate | occur | produces in the building 12 can be suppressed effectively.

  Next, a vibration damping structure 44 according to the second embodiment of the present invention will be described.

  In the second embodiment, the vibration damping mechanism 14 in the first embodiment is arranged outside the column 28. Therefore, in the following description, the same components as those in the first embodiment are denoted by the same reference numerals and are appropriately omitted.

  FIG. 5 shows the vibration damping structure 44 of the second embodiment. The damping structure 44 is constructed by arranging a plurality of damping mechanisms 48 in an S structure building 46 as a structure built on the ground 20.

  As shown in FIG. 5, the vibration control mechanisms 48 are arranged on all floors from the left and right first floors of the building 46 to the rooftop floor.

  As shown in FIG. 6, the vibration damping mechanism 48 disposed on the left side of the building 46 includes the damper member 16 and the rigid member 18 and is disposed across two layers. That is, as shown in FIG. 5, if the number of floors of the building 46 is n, the vibration control mechanism 48 is arranged across the nth floor and the (n + 2) th floor.

  For example, the vibration damping mechanism 48 is disposed from the 17th floor to the 19th floor, and the vibration damping mechanism 48 disposed above the floor is from the 18th floor to the 20th floor. The following description will be made on one vibration control mechanism 48 arranged from the nth floor to the (n + 2) th floor.

  As shown in FIG. 6, the damping structure 44 includes an upper beam 22 provided at the uppermost part of the two layers, a lower beam 24 provided at the lowermost part of the two layers, and the upper beam 22 and the lower beam 24. It has a beam 50 as an intermediate member provided between them, and a column 28 as a support member standing up and down.

  The column 28 is erected on the outer periphery of the building 46, and the upper beam 22 and the lower beam 24 are joined to each other. The beam 50 is joined to the column 28 and protrudes outside the building 46.

  The upper end portion of the damper member 16 is joined by a joint portion (joint portion 52) between the column 28 and the upper beam 22. Further, the damper member 16 is disposed obliquely toward the outside lower side of the building 46.

  The lower end portion of the rigid member 18 is pin-coupled by a joint portion (joint portion 54) between the column 28 and the lower beam 24. Further, the rigid member 18 is disposed obliquely toward the upper outside of the building 46.

  Further, the lower end portion of the damper member 16 and the upper end portion of the rigid member 18 are pin-coupled to the beam 50 by a coupling portion 56. That is, the damper member 16 is disposed between the upper beam 22 and the beam 50, and the rigid member 18 is disposed between the lower beam 24 and the beam 50 where the damper member 16 is not disposed.

  Further, with these structures, the rigid member 18 can transmit the axial deformation of the column 28 to the damper member 16.

  FIG. 8 shows a vibration control mechanism 48 disposed on the right side of the building 46. Since the vibration control mechanism 48 arranged on the left side of the building 46 and the vibration control mechanism 48 arranged on the right side of the building 46 have a line symmetrical configuration with respect to the central axis of the building 46, The description of the vibration control mechanism 48 arranged in the above will be omitted. The vibration control mechanism 48 disposed on the right side of the building 46 is also disposed from the nth floor to the (n + 2) th floor.

  Next, the operation and effect of the vibration damping structure 44 according to the second embodiment of the present invention will be described.

  First, as shown in FIG. 7, when a horizontal force P from left to right is applied to the building 46 and shear deformation and bending deformation occur at the same time in the building 46, a vibration damping mechanism disposed on the left side of the building 46. The operation and effect of 48 will be described.

  Due to the shear deformation generated in the building 46, the upper beam 22 and the beam 50 move relative to each other in the horizontal direction.

  Therefore, the coupling portion 52 between the upper beam 22 and the upper end portion of the damper member 16 moves in a direction away from the coupling portion 56 between the beam 50 and the lower end portion of the damper member 16.

  Since the damper member 16 extends (arrow 60) with the movement of the coupling portion 52 (arrow 58), a damping effect can be exerted and shear deformation generated in the building 46 can be suppressed.

  Further, since the column 28 extends upward due to the bending deformation generated in the building 46, the coupling portion 52 between the column 28 and the upper end portion of the damper member 16 with respect to the coupling portion 56 between the beam 50 and the lower end portion of the damper member 16. Move away.

  Since the damper member 16 extends (arrow 62) with the movement of the coupling portion 52 (arrow 64), a damping effect can be exerted and bending deformation occurring in the building 46 can be suppressed.

  The column 28 extends upward due to the bending deformation, and the connecting portion 52 between the upper beam 22 and the upper end portion of the damper member 16 tends to move upward. At this time, the beam 50 of the portion protruding to the outside of the building 46 rotates clockwise with the joint portion of the beam 50 and the column 28 as the rotation center, and accordingly, the beam 50 and the lower end portion of the damper member 16 The connecting portion 56 is going to move upward. However, the rigid member 18 has an upper end portion coupled to the lower end portion of the damper member 16 and the beam 50, and a lower end portion coupled to the column 28, and the amount of elongation deformation of the rigid member 18 is small. Therefore, the upward movement of the coupling portion 56 between the beam 50 and the lower end portion of the damper member 16 is prevented. Thereby, the damper member 16 is fully extended.

  Further, the damper member 16 extends due to the shear deformation generated in the building 46 (arrow 60), and the damper member 16 extends also due to the bending deformation generated in the building 46 (arrow 62), so the deformation direction of the damper member 16 becomes the same. . Therefore, the deformation of the damper member 16 due to the bending deformation generated in the building 46 does not reduce the deformation amount of the damper member 16 due to the shear deformation generated in the building 46.

  Next, when a horizontal force from left to right is applied to the building 46 so that shear deformation and bending deformation occur simultaneously in the building 46, the action of the vibration control mechanism 48 shown in FIG. The effects will be described.

  Due to the shear deformation generated in the building 46, the upper floor beam 22 and the beam 50 relatively move in the horizontal direction.

  Therefore, the coupling portion 52 between the upper beam 22 and the upper end portion of the damper member 16 moves in a direction approaching the coupling portion 56 between the beam 50 and the lower end portion of the damper member 16.

  Since the damper member 16 contracts as the coupling portion 52 moves, the damping member 16 exhibits a damping effect, and shear deformation generated in the building 46 can be suppressed.

  Further, since the column 28 contracts downward due to the bending deformation generated in the building 46, the coupling portion 52 between the column 28 and the upper end portion of the damper member 16 with respect to the coupling portion 56 between the beam 50 and the lower end portion of the damper member 16. Move in the approaching direction.

  And since the damper member 16 shrinks with the movement of this coupling | bond part 52, a damping effect is exhibited and the bending deformation generate | occur | produced in the building 46 can be suppressed.

  The column 28 contracts downward due to the bending deformation, and the connecting portion 52 between the upper floor beam 22 and the upper end portion of the damper member 16 tends to move downward. At this time, the beam 50 of the portion protruding to the outside of the building 46 rotates clockwise with the joint portion of the beam 50 and the column 28 as the rotation center, and accordingly, the beam 50 and the lower end portion of the damper member 16 The connecting portion 56 is going to move downward. However, the rigid member 18 has an upper end portion coupled to the lower end portion of the damper member 16 and the beam 50 and a lower end portion coupled to the column 28, and the amount of contraction deformation of the rigid member 18 is small. Therefore, the downward movement of the coupling portion 56 between the beam 50 and the lower end portion of the damper member 16 is prevented. Thereby, the damper member 16 contracts sufficiently.

  Further, the damper member 16 contracts due to the shear deformation generated in the building 46, and the damper member 16 contracts also due to the bending deformation generated in the building 46. Therefore, the deformation direction of the damper member 16 is the same. Therefore, the deformation of the damper member 16 due to the bending deformation generated in the building 46 does not reduce the deformation amount of the damper member 16 due to the shear deformation generated in the building 46.

  Accordingly, the shear deformation and the bending deformation generated in the building 46 can be suppressed, and the effect of the damper member 16 for suppressing the shear deformation generated in the building 46 is not reduced by the bending deformation. Moreover, the structural safety of the building 46 is improved by suppressing the bending deformation of the building 46 that has been difficult in the past.

  When a horizontal force from the right to the left is applied to the building 46, the case described above (the horizontal force P from the left to the right is applied to the building 46) by the vibration control mechanism 48 disposed on the right side of the building 46. The same action and effect as the vibration damping mechanism 48 arranged on the left side of the building 46 is obtained, and the vibration damping mechanism 48 arranged on the left side of the building 46 has the above-described case (the building 46). When a horizontal force P from left to right is applied), the same operation and effect as those of the vibration control mechanism 48 arranged on the right side of the building 46 can be obtained.

  Further, since the column 28 erected on the outer periphery of the building 46 has a large amount of axial deformation of the column 28 when bending deformation occurs in the building 46, the damper member 16 can be greatly deformed. Therefore, the bending deformation generated in the building 46 can be effectively suppressed.

  Further, since the vibration damping structure 44 can be constructed simply by providing the rigid member 18 and the damper member 16 in an existing building, the repair work can be easily performed. In the case of a new construction, the cost can be reduced.

  Next, a vibration damping structure 66 according to a third embodiment of the present invention will be described.

  In the third embodiment, the support member that is the pillar 28 in the first embodiment is a pillar that follows the core wall built inside the building. Therefore, in the following description, the same components as those in the first embodiment are denoted by the same reference numerals and are appropriately omitted.

  FIG. 9 shows a vibration damping structure 66 of the third embodiment. The damping structure 66 is constructed by arranging a plurality of damping mechanisms 70 in an S-structure building 68 as a structure built on the ground 20.

  As shown in FIG. 9, the vibration damping mechanism 70 is arranged on all floors from the first floor on the left and right of the building 68 to the rooftop floor.

  As shown in FIG. 10, the vibration damping mechanism 70 disposed on the left side of the high-rigidity core wall 76 constructed in the building 68 includes the damper member 16 and the rigid member 18 and is disposed across two layers. Has been. That is, as shown in FIG. 9, when the number of floors of the building 68 is n, the vibration damping mechanism 70 is arranged from the nth floor to the (n + 2) th floor.

  For example, the vibration damping mechanism 70 is arranged from the 17th floor to the 19th floor, and the vibration damping mechanism 70 disposed above the floor is from the 18th floor to the 20th floor. The following description will be made on one vibration control mechanism 70 arranged from the nth floor to the (n + 2) th floor.

  As shown in FIG. 10, the damping structure 70 disposed on the left side of the core wall 76 includes an upper beam 22 provided at the uppermost part of the two layers and a lower beam 24 provided at the lowermost part of the two layers. , A beam 72 as an intermediate member provided between the upper beam 22 and the lower beam 24, and a column 74 as a support member standing up and down.

  The column 74 is erected along the core wall 76, and the upper beam 22 and the lower beam 24 are joined to each other. The beam 72 is joined to the column 74.

  The upper end portion of the damper member 16 is pin-coupled by a joint portion (joint portion 78) between the column 74 and the upper beam 22. Further, the damper member 16 is disposed obliquely toward the lower side on the side away from the core wall 76.

  The lower end portion of the rigid member 18 is pin-coupled at a joint portion (joint portion 80) between the column 74 and the lower beam 24. Further, the rigid member 18 is disposed obliquely upward on the side away from the core wall 76.

  Further, the lower end portion of the damper member 16 and the upper end portion of the rigid member 18 are pin-coupled to the beam 72 by the coupling portion 82. That is, the damper member 16 is disposed between the upper beam 22 and the beam 72, and the rigid member 18 is disposed between the lower beam 24 and the beam 72 where the damper member 16 is not disposed.

  Further, with these structures, the rigid member 18 can transmit the axial deformation of the column 74 to the damper member 16.

  FIG. 12 shows the vibration damping mechanism 70 disposed on the right side of the core wall 76. Since the vibration damping mechanism 70 disposed on the left side of the core wall 76 and the vibration damping mechanism 70 disposed on the right side of the core wall 76 have a line-symmetric configuration with respect to the central axis of the core wall 76, the core A description of the vibration damping mechanism 70 disposed on the right side of the wall 76 is omitted. The vibration control mechanism 70 disposed on the right side of the core wall 76 is also disposed from the nth floor to the (n + 2) th floor.

  Next, the operation and effect of the vibration damping structure 66 according to the third embodiment of the present invention will be described.

  First, as shown in FIG. 11, when a horizontal force P from left to right is applied to the building 68 and shear deformation and bending deformation occur at the same time in the building 68, vibration damping disposed on the left side of the core wall 76 is performed. The operation and effect of the mechanism 70 will be described.

  Due to the shear deformation generated in the building 68, the upper beam 22 and the beam 72 relatively move in the horizontal direction.

  Therefore, the connecting portion 78 between the upper beam 22 and the upper end portion of the damper member 16 moves in a direction away from the connecting portion 82 between the beam 72 and the lower end portion of the damper member 16.

  Since the damper member 16 extends (arrow 86) with the movement of the coupling portion 78 (arrow 84), a damping effect can be exerted and shear deformation generated in the building 68 can be suppressed.

  Further, since the pillar 74 extends upward due to the bending deformation generated in the building 68, the joint portion 78 between the pillar 74 and the upper end portion of the damper member 16 is connected to the joint portion 82 between the beam 72 and the lower end portion of the damper member 16. Move away.

  Since the damper member 16 extends (arrow 90) with the movement of the coupling portion 78 (arrow 88), a damping effect can be exerted and bending deformation occurring in the building 68 can be suppressed.

  The column 74 extends upward due to the bending deformation, and the joint 78 between the upper beam 22 and the damper member 16 moves upward. At this time, the beam 72 rotates clockwise with the joint between the beam 72 and the column 74 as the center of rotation, and accordingly, the joint 82 between the beam 72 and the lower end of the damper member 16 moves upward. try to. However, the rigid member 18 has an upper end portion coupled to the lower end portion of the damper member 16 and the beam 72, and a lower end portion coupled to the column 74, and the amount of deformation of the damper member 18 is small. Therefore, the damper member 16 extends sufficiently.

  Further, the damper member 16 extends due to the shear deformation that occurs in the building 68 (arrow 86), and the damper member 16 also extends due to the bending deformation that occurs in the building 68 (arrow 90), so the deformation direction of the damper member 16 is the same. . Therefore, the deformation of the damper member 16 due to the bending deformation generated in the building 68 does not reduce the deformation amount of the damper member 16 due to the shear deformation generated in the building 68.

  Next, when a horizontal force from left to right is applied to the building 68 so that shear deformation and bending deformation occur at the same time in the building 68, the vibration control mechanism 70 shown in FIG. The operation and effect will be described.

  Due to the shear deformation generated in the building 68, the upper beam 22 and the beam 72 relatively move in the horizontal direction.

  Therefore, the coupling portion 78 between the upper beam 22 and the upper end portion of the damper member 16 moves in a direction approaching the coupling portion 82 between the beam 72 and the lower end portion of the damper member 16.

  Since the damper member 16 contracts as the coupling portion 78 moves, a damping effect can be exhibited and shear deformation generated in the building 68 can be suppressed.

  Further, since the pillar 74 is contracted downward by bending deformation generated in the building 68, the joint portion 78 between the pillar 74 and the upper end portion of the damper member 16 is connected to the joint portion 82 between the beam 72 and the lower end portion of the damper member 16. Move in the approaching direction.

  Since the damper member 16 contracts as the coupling portion 78 moves, a damping effect can be exerted, and bending deformation generated in the building 68 can be suppressed.

  The column 74 contracts downward due to the bending deformation, and the joint 78 between the upper beam 22 and the upper end of the damper member 16 moves downward. At this time, the beam 72 rotates clockwise around the joint between the beam 72 and the column 74 as a center of rotation, and accordingly, the joint 82 between the beam 72 and the lower end of the damper member 16 moves downward. try to. However, the rigid member 18 has an upper end portion coupled to the lower end portion of the damper member 16 and the beam 72, and a lower end portion coupled to the column 74, and the amount of contraction deformation of the rigid member 18 is small. Therefore, the damper member 16 is sufficiently contracted.

  Further, the damper member 16 contracts due to the shear deformation generated in the building 68, and the damper member 16 contracts also due to the bending deformation generated in the building 68. Therefore, the deformation direction of the damper member 16 is the same. Therefore, the deformation of the damper member 16 due to the bending deformation generated in the building 68 does not reduce the deformation amount of the damper member 16 due to the shear deformation generated in the building 68.

  As a result, shear deformation and bending deformation that occur in the building 68 can be suppressed, and the effect of the damper member 16 that suppresses shear deformation that occurs in the building 68 is not reduced by bending deformation. Further, the structural safety of the building 68 is improved by suppressing the bending deformation of the building 68 that has been difficult in the past.

  When a horizontal force from the right to the left is applied to the building 68, the case described above (the horizontal force P from the left to the right is applied to the building 68) by the vibration control mechanism 70 disposed on the right side of the core wall 76. In this case, the same operation and effect as the vibration damping mechanism 70 arranged on the left side of the core wall 76 can be obtained. In the case where a horizontal force P directed from the left to the right is applied to the building 68, the same operations and effects as those of the vibration control mechanism 70 disposed on the right side of the building 68 are obtained.

  Further, since the pillar 74 that follows the core wall 76 has a large axial expansion / contraction amount when the building 68 undergoes bending deformation, the damper member 16 can be greatly deformed. Therefore, the bending deformation generated in the building 68 can be effectively suppressed.

  Further, since the vibration damping structure 66 can be constructed simply by providing the rigid member 18 and the damper member 16 in an existing building, repair work can be easily performed. In the case of a new construction, the cost can be reduced.

  Next, a vibration damping structure 92 according to a fourth embodiment of the present invention will be described.

  In the fourth embodiment, the intermediate member which is the beam 26 in the first embodiment is a connecting beam. Therefore, in the following description, the same components as those in the first embodiment are denoted by the same reference numerals and are appropriately omitted.

  FIG. 13 shows a vibration damping structure 92 according to the fourth embodiment. The vibration control structure 92 is constructed by arranging a plurality of vibration control mechanisms 112 in an S-structure building 94 as a structure built on the ground 20.

  As shown in FIG. 13, the vibration damping mechanism 112 is arranged at all levels from the left and right first floors of the building 94 to the rooftop floor.

  The vibration damping mechanism 112 disposed on the left side of the building 94 includes a damper member 16 and a rigid member 18 as illustrated in FIG. 14 and is disposed at each level as illustrated in FIG. The following description will be given with respect to the vibration control mechanism 112 arranged in one hierarchy.

  As shown in FIG. 14, the damping structure 92 includes an upper floor beam 96, a lower floor beam 98, a connecting beam 100 as an intermediate member provided between the upper floor beam 96 and the lower floor beam 98, And it has the pillar 28 as a supporting member erected up and down.

  The column 28 is erected on the outer periphery of the building 94, and the upper floor beam 96 and the lower floor beam 98 are joined.

  The lower end portion of the damper member 16 is pin-coupled by a joint portion (joint portion 30) between the column 28 and the lower floor beam 98. Further, the damper member 16 is disposed obliquely toward the inside upper side of the building 94.

  The upper end portion of the rigid member 18 is pin-coupled by a joint portion (joint portion 32) between the column 28 and the upper floor beam 96. Further, the rigid member 18 is disposed obliquely toward the inner lower side of the building 94.

  Further, the upper end portion of the damper member 16 is pin-coupled at a coupling portion 102 in which the lower end portion of the rigid member 18 and the connecting beam 100 are rigidly coupled. That is, the damper member 16 is disposed between the lower floor beam 98 and the connecting beam 100, and the rigid member 18 is disposed between the upper floor beam 96 and the connecting beam 100 where the damper member 16 is not disposed. ing.

  Further, with these structures, the rigid member 18 can transmit the axial deformation of the column 28 to the damper member 16.

  FIG. 16 shows the vibration control mechanism 112 arranged on the right side of the building 94. Since the vibration control mechanism 112 disposed on the left side of the building 94 and the vibration control mechanism 112 disposed on the right side of the building 94 have a line-symmetric configuration with respect to the central axis of the building 94, The description of the vibration control mechanism 112 arranged in the above will be omitted. The vibration control mechanism 112 arranged on the right side of the building 94 is also arranged in each level.

  Next, operations and effects of the vibration control structure 92 according to the fourth embodiment of the present invention will be described.

  First, as shown in FIG. 15, a vibration damping mechanism disposed on the left side of the building 94 when a horizontal force P from left to right is applied to the building 94 and shear deformation and bending deformation occur simultaneously in the building 94. The operation and effect of 112 will be described.

  Due to the shear deformation generated in the building 94, the lower floor beam 98 and the upper floor beam 96 are relatively moved in the horizontal direction. At this time, since a stable trapezoid is formed by the rigid member 18, the connecting beam 100, and the upper floor beam 96, the connecting beam 100 and the lower floor beam 98 connected to the upper floor beam 96 via the rigid member 18 are also included. Move relative to the horizontal.

  Therefore, the connecting portion 102 between the connecting beam 100 and the upper end portion of the damper member 16 moves in a direction away from the connecting portion 30 between the lower floor beam 98 and the lower end portion of the damper member 16.

  Further, the damper member 16 extends (arrow 106) with the movement of the coupling portion 102 (arrow 104), so that a damping effect can be exerted and shear deformation generated in the building 94 can be suppressed.

  Further, the column 28 extends upward by bending deformation generated in the building 94. Here, the rigid member 18 has an upper end coupled to the column 28 and a lower end coupled to the upper end of the damper member 16, and the amount of expansion deformation of the rigid member 18 is small. A stable trapezoid is formed by the rigid member 18, the connecting beam 100, and the upper floor beam 96. Therefore, the upper end of the damper member 16 is pulled upward by the pillar 28 extending upward (arrow 108).

  Since the damper member 16 extends (arrow 110) as the upper end of the damper member 16 is pulled up, a damping effect can be exerted and bending deformation occurring in the building 94 can be suppressed.

  Further, the damper member 16 is extended by the shear deformation generated in the building 94 (arrow 106), and the damper member 16 is also extended by the bending deformation generated in the building 94 (arrow 110). Therefore, the deformation direction of the damper member 16 is the same. . Therefore, the deformation of the damper member 16 due to the bending deformation generated in the building 94 does not reduce the deformation amount of the damper member 16 due to the shear deformation generated in the building 94.

  Next, when a horizontal force from left to right is applied to the building 94 and shear deformation and bending deformation occur simultaneously in the building 94, the vibration control mechanism 112 shown in FIG. The effects will be described.

  Due to the shear deformation generated in the building 94, the lower floor beam 98 and the upper floor beam 96 are relatively moved in the horizontal direction. At this time, since a stable trapezoid is formed by the rigid member 18, the connecting beam 100, and the upper floor beam 96, the connecting beam 100 and the lower floor beam 98 connected to the upper floor beam 96 via the rigid member 18 are also included. Move relative to the horizontal.

  Therefore, the connecting portion 102 between the connecting beam 100 and the upper end portion of the damper member 16 moves in a direction approaching the connecting portion 30 between the lower floor beam 98 and the lower end portion of the damper member 16.

  Since the damper member 16 contracts with the movement of the coupling portion 102, a damping effect can be exhibited, and shear deformation occurring in the building 94 can be suppressed.

  Further, the column 28 contracts downward due to bending deformation generated in the building 94. Here, the rigid member 18 has an upper end coupled to the column 28 and a lower end coupled to the upper end of the damper member 16, and the amount of contraction deformation of the rigid member 18 is small. A stable trapezoid is formed by the rigid member 18, the connecting beam 100, and the upper floor beam 96. Therefore, the upper end portion of the damper member 16 is pushed downward by shrinking the column 28 downward.

  Since the damper member 16 contracts as the upper end of the damper member 16 is pushed down, a damping effect can be exerted, and bending deformation occurring in the building 94 can be suppressed.

  Further, the damper member 16 contracts due to the shear deformation generated in the building 94, and the damper member 16 contracts also due to the bending deformation generated in the building 94, so that the deformation direction of the damper member 16 is the same. Therefore, the deformation of the damper member 16 due to the bending deformation generated in the building 94 does not reduce the deformation amount of the damper member 16 due to the shear deformation generated in the building 94.

  Thus, the shear deformation and the bending deformation generated in the building 94 can be suppressed, and the effect of the damper member 16 for suppressing the shear deformation generated in the building 94 is not reduced by the bending deformation. Further, the structural safety of the building 94 is improved by suppressing the bending deformation of the building 94, which has been difficult in the past.

  When a horizontal force from the right to the left is applied to the building 94, the case described above (the horizontal force P from the left to the right is applied to the building 94) by the vibration control mechanism 112 arranged on the right side of the building 94. The same operation and effect as those of the vibration damping mechanism 112 disposed on the left side of the building 94 can be obtained, and the vibration damping mechanism 112 disposed on the left side of the building 94 can be used as described above (the building 94). When the horizontal force P from left to right is applied), the same operation and effect as the vibration damping mechanism 112 disposed on the right side of the building 94 can be obtained.

  Further, since the column 28 erected on the outer periphery of the building 94 has a large amount of axial deformation of the column 28 when bending deformation occurs in the building 94, the damper member 16 can be greatly deformed. Therefore, the bending deformation generated in the building 94 can be effectively suppressed.

  Next, a vibration damping structure 114 according to a fifth embodiment of the present invention will be described.

  In the fifth embodiment, the intermediate member that is the connecting beam 100 in the fourth embodiment is a brace member. Therefore, in the following description, the same components as those in the fourth embodiment are denoted by the same reference numerals and are appropriately omitted.

  FIG. 17 shows the vibration damping structure 114 of the fifth embodiment. The damping structure 114 is constructed by arranging a plurality of damping mechanisms 118 in an S-shaped building 116 as a structure built on the ground 20.

  As shown in FIG. 17, the vibration control mechanisms 118 are arranged at all levels from the left and right first floors of the building 116 to the rooftop floor.

  The damping mechanism 118 disposed on the left side of the building 116 includes the damper member 16 and the rigid member 18 as shown in FIG. 18, and is disposed at each level as shown in FIG. The following description will be given with respect to the vibration control mechanism 118 arranged in one hierarchy.

  As shown in FIG. 18, the damping structure 114 includes an upper floor beam 96, a lower floor beam 98, and a brace member 120 as an intermediate member provided between the upper floor beam 96 and the lower floor beam 98, And it has the pillar 28 as a supporting member erected up and down.

  The upper end portion of the brace member 120 is pin-coupled to a joint portion between the inner column 132 and the upper floor beam 96 that are erected on the inner side of the building 116 than the column 28. Further, the brace member 120 is disposed obliquely toward the outside lower side of the building 116.

  The column 28 is erected on the outer periphery of the building 116, and the upper floor beam 96 and the lower floor beam 98 are joined.

  The lower end portion of the damper member 16 is pin-coupled by a joint portion (joint portion 30) between the column 28 and the lower floor beam 98. Further, the damper member 16 is disposed obliquely toward the upper inside of the building 116.

  The upper end portion of the rigid member 18 is pin-coupled by a joint portion (joint portion 32) between the column 28 and the upper floor beam 96. Further, the rigid member 18 is disposed obliquely toward the inner lower side of the building 116.

  Further, the upper end portion of the damper member 16 is pin-coupled at a coupling portion 122 where the lower end portion of the rigid member 18 and the brace member 120 are pin-coupled. That is, the damper member 16 is disposed between the lower floor beam 98 and the brace member 120, and the rigid member 18 is disposed between the upper floor beam 96 and the brace member 120 where the damper member 16 is not disposed. ing.

  Further, with these structures, the rigid member 18 can transmit the axial deformation of the column 28 to the damper member 16.

  FIG. 20 shows the vibration control mechanism 118 arranged on the right side of the building 116. The vibration control mechanism 118 disposed on the left side of the building 116 and the vibration control mechanism 118 disposed on the right side of the building 116 are configured to be line-symmetric with respect to the central axis of the building 116, so The description of the vibration control mechanism 118 arranged in the above will be omitted. A vibration control mechanism 118 disposed on the right side of the building 116 is also disposed in each layer.

  Next, operations and effects of the vibration control structure 114 according to the fifth embodiment of the present invention will be described.

  First, as shown in FIG. 19, when a horizontal force P from left to right is applied to the building 116 and shear deformation and bending deformation occur at the same time in the building 116, a vibration control mechanism disposed on the left side of the building 116. The operation and effect of 118 will be described.

  Due to the shear deformation generated in the building 116, the lower floor beam 98 and the upper floor beam 96 are relatively moved in the horizontal direction. At this time, since the stable triangle is formed by the rigid member 18, the brace member 120, and the upper floor beam 96, the brace member 120 whose upper end is coupled to the joint between the inner column 132 and the upper floor beam 96, The lower floor beam 98 is also relatively moved in the horizontal direction.

  Therefore, the connecting portion 122 between the brace member 120 and the upper end portion of the damper member 16 moves away from the connecting portion 30 between the lower floor beam 98 and the lower end portion of the damper member 16.

  Then, the damper member 16 extends (arrow 126) with the movement of the coupling portion 122 (arrow 124), so that a damping effect can be exhibited and shear deformation generated in the building 116 can be suppressed.

  Further, the column 28 extends upward by bending deformation generated in the building 116.

  Here, the rigid member 18 has an upper end coupled to the column 28 and a lower end coupled to the upper end of the damper member 16, and the amount of expansion deformation of the rigid member 18 is small. Further, a stable triangle is formed by the rigid member 18, the brace member 120 and the upper floor beam 96. Therefore, the upper end of the damper member 16 is pulled upward by the pillar 28 extending upward (arrow 128).

  Since the damper member 16 extends (arrow 130) as the upper end of the damper member 16 is pulled up, a damping effect can be exerted and bending deformation occurring in the building 116 can be suppressed.

  Further, the damper member 16 extends due to the shear deformation generated in the building 116 (arrow 126), and the damper member 16 extends due to the bending deformation generated in the building 116 (arrow 130), so that the deformation direction of the damper member 16 is the same. . Therefore, the deformation of the damper member 16 due to the bending deformation that occurs in the building 116 does not reduce the amount of deformation of the damper member 16 due to the shear deformation that occurs in the building 116.

  Next, when a horizontal force from left to right is applied to the building 116 and shear deformation and bending deformation occur simultaneously in the building 116, the vibration control mechanism 118 shown in FIG. The effects will be described.

  Due to the shear deformation generated in the building 116, the lower floor beam 98 and the upper floor beam 96 are relatively moved in the horizontal direction. At this time, since the stable triangle is formed by the rigid member 18, the brace member 120, and the upper floor beam 96, the brace member 120 whose upper end is coupled to the joint between the inner column 132 and the upper floor beam 96, The lower floor beam 98 is also relatively moved in the horizontal direction.

  Therefore, the connecting portion 122 between the brace member 120 and the upper end portion of the damper member 16 moves toward the connecting portion 30 between the lower floor beam 98 and the lower end portion of the damper member 16.

  Since the damper member 16 contracts as the connecting portion 122 moves, the damping effect can be exerted and shear deformation generated in the building 116 can be suppressed.

  Further, the column 28 contracts downward due to bending deformation generated in the building 116. Here, the rigid member 18 has an upper end coupled to the column 28 and a lower end coupled to the upper end of the damper member 16, and the amount of contraction deformation of the rigid member 18 is small. Further, a stable triangle is formed by the rigid member 18, the brace member 120 and the upper floor beam 96. Therefore, the upper end portion of the damper member 16 is pushed downward by shrinking the column 28 downward.

  Since the damper member 16 contracts as the upper end of the damper member 16 is pushed down, a damping effect can be exerted, and bending deformation occurring in the building 116 can be suppressed.

  Further, the damper member 16 contracts due to the shear deformation generated in the building 116, and the damper member 16 contracts also due to the bending deformation generated in the building 116, so that the deformation direction of the damper member 16 is the same. Therefore, the deformation of the damper member 16 due to the bending deformation that occurs in the building 116 does not reduce the amount of deformation of the damper member 16 due to the shear deformation that occurs in the building 116.

  As a result, shear deformation and bending deformation that occur in the building 116 can be suppressed, and the effect of the damper member 16 that suppresses shear deformation that occurs in the building 116 is not reduced by bending deformation. Moreover, the structural safety of the building 116 is improved by suppressing the bending deformation of the building 116 which has been difficult in the past.

  When a horizontal force from the right to the left is applied to the building 116, the case described above (the horizontal force P from the left to the right is applied to the building 116) by the vibration control mechanism 118 arranged on the right side of the building 116. The same action and effect as the vibration damping mechanism 118 arranged on the left side of the building 116 is obtained, and the case described above (the building 116) is obtained by the vibration damping mechanism 118 arranged on the left side of the building 116. When a horizontal force P from left to right is applied), the same operation and effect as the vibration control mechanism 118 disposed on the right side of the building 116 can be obtained.

  Further, since the column 28 erected on the outer periphery of the building 116 has a large amount of axial deformation of the column 28 when bending deformation occurs in the building 116, the damper member 16 can be greatly deformed. Therefore, bending deformation occurring in the building 116 can be effectively suppressed.

  Next, a vibration damping structure 134 according to a sixth embodiment of the present invention will be described.

  In the sixth embodiment, the structure of the vibration damping mechanism 118 of the fifth embodiment is turned upside down, and a pillar that follows the core wall built inside the building is used as a support member. The support member, the damper member, and the rigid member Are combined. Therefore, in the following description, the same components as those in the fifth embodiment are denoted by the same reference numerals and will be appropriately omitted.

  FIG. 21 shows a vibration damping structure 134 according to the sixth embodiment. The vibration damping structure 134 is constructed by arranging a plurality of vibration damping mechanisms 138 in an S building 136 as a structure built on the ground 20.

  As shown in FIG. 21, the vibration damping mechanism 138 is arranged at all levels from the left and right first floors of the building 136 to the rooftop floor.

  The vibration damping mechanism 138 arranged on the left side of the building 136 includes the damper member 16 and the rigid member 18 as shown in FIG. 22, and is arranged in each layer as shown in FIG. The following description will be given with respect to the vibration control mechanism 138 arranged in one hierarchy.

  As shown in FIG. 22, the damping structure 134 includes an upper floor beam 96, a lower floor beam 98, a brace member 140 as an intermediate member provided between the upper floor beam 96 and the lower floor beam 98, It has a column 74 and an outer column 135 as support members standing up and down.

  The pillar 74 is erected along a core wall 76 constructed inside the building 136, and the upper floor beam 96 and the lower floor beam 98 are joined. In addition, the outer pillar 135 is erected on or near the outer periphery of the building 136, and the upper floor beam 96 and the lower floor beam 98 are joined. The vicinity of the outer periphery of the building 136 means a position inside the building 136 and close to the outer periphery of the building 136.

  A lower end portion of the brace member 140 is pin-coupled to a joint portion between the outer column 135 and the lower floor beam 98. Further, the brace member 140 is disposed obliquely toward the upper inside of the building 136.

  The upper end portion of the damper member 16 is pin-coupled by a joint portion (joint portion 142) between the column 74 and the upper floor beam 96. Further, the damper member 16 is disposed obliquely toward the lower side on the side away from the core wall 76.

  The lower end portion of the rigid member 18 is pin-connected by a joint portion (joint portion 114) between the column 74 and the lower floor beam 98. Further, the rigid member 18 is disposed obliquely upward on the side away from the core wall 76.

  Further, the lower end portion of the damper member 16 is pin-coupled at a coupling portion 146 where the upper end portion of the rigid member 18 and the brace member 140 are pin-coupled. That is, the damper member 16 is disposed between the upper floor beam 96 and the brace member 140, and the rigid member 18 is disposed between the lower floor beam 98 and the brace member 140 where the damper member 16 is not disposed. ing.

  Further, with these structures, the rigid member 18 can transmit the axial deformation of the column 74 to the damper member 16.

  FIG. 24 shows the vibration damping mechanism 138 disposed on the right side of the core wall 76. Since the vibration damping mechanism 138 disposed on the left side of the core wall 76 and the vibration damping mechanism 138 disposed on the right side of the core wall 76 are configured to be axisymmetric with respect to the central axis of the core wall 76, the core A description of the vibration damping mechanism 138 disposed on the right side of the wall 76 is omitted. A damping mechanism 138 disposed on the right side of the core wall 76 is also disposed in each layer.

  Next, operations and effects of the vibration damping structure 134 according to the sixth embodiment of the present invention will be described.

  First, as shown in FIG. 23, when a horizontal force P from the left to the right is applied to the building 136 and shear deformation and bending deformation occur at the same time in the building 136, vibration damping disposed on the left side of the core wall 76 is performed. The operation and effect of the mechanism 138 will be described.

  Due to the shear deformation generated in the building 136, the lower floor beam 98 and the upper floor beam 96 are relatively moved in the horizontal direction. At this time, since the stable triangle is formed by the rigid member 18, the brace member 140, and the lower floor beam 98, the brace member 140 whose lower end portion is coupled to the joint portion between the outer column 135 and the lower floor beam 98; The upper floor beam 96 is also relatively moved in the horizontal direction.

  Therefore, the connecting portion 146 between the brace member 140 and the lower end portion of the damper member 16 moves in a direction away from the connecting portion 142 between the upper floor beam 96 and the upper end portion of the damper member 16.

  The damper member 16 expands (arrow 150) with the movement of the coupling portion 142 (arrow 148), so that a damping effect can be exerted and shear deformation occurring in the building 136 can be suppressed.

  Further, the pillar 74 extends upward by bending deformation generated in the building 136.

  Here, the rigid member 18 has a lower end portion coupled to the column 74 and an upper end portion coupled to the lower end portion of the damper member 16, and the amount of elongation deformation of the rigid member 18 is small. Further, a stable triangle is formed by the rigid member 18, the brace member 140, and the lower floor beam 98. Therefore, the upper end portion of the damper member 16 is pulled upward by the pillar 74 extending upward (arrow 152).

  Since the damper member 16 extends (arrow 154) as the upper end of the damper member 16 is pulled up, a damping effect can be exerted and bending deformation occurring in the building 136 can be suppressed.

  Further, the damper member 16 extends due to the shear deformation generated in the building 136 (arrow 150), and the damper member 16 extends also due to the bending deformation generated in the building 136 (arrow 154), so that the deformation direction of the damper member 16 becomes the same. . Therefore, the deformation of the damper member 16 due to the bending deformation occurring in the building 136 does not reduce the deformation amount of the damper member 16 due to the shear deformation occurring in the building 136.

  Next, when a horizontal force from left to right is applied to the building 136 and shear deformation and bending deformation occur at the same time in the building 136, the vibration control mechanism 138 shown in FIG. The operation and effect will be described.

  Due to the shear deformation generated in the building 136, the lower floor beam 98 and the upper floor beam 96 are relatively moved in the horizontal direction. At this time, since the stable triangle is formed by the rigid member 18, the brace member 140, and the lower floor beam 98, the brace member 140 whose lower end portion is coupled to the joint portion between the outer column 135 and the lower floor beam 98; The upper floor beam 96 is also relatively moved in the horizontal direction.

  Therefore, the connecting portion 146 between the brace member 140 and the lower end portion of the damper member 16 moves in a direction approaching the connecting portion 142 between the upper floor beam 96 and the upper end portion of the damper member 16.

  Since the damper member 16 contracts as the coupling portion 142 moves, a damping effect can be exerted, and shear deformation that occurs in the building 136 can be suppressed.

  Further, the pillar 74 is contracted downward by bending deformation generated in the building 136. Here, the rigid member 18 has a lower end portion coupled to the column 74 and an upper end portion coupled to the lower end portion of the damper member 16, and the amount of contraction deformation of the rigid member 18 is small. Further, a stable triangle is formed by the rigid member 18, the brace member 140, and the lower floor beam 98. Therefore, the upper end portion of the damper member 16 is pushed downward by shrinking the column 74 downward.

  Since the damper member 16 contracts as the upper end of the damper member 16 is pushed down, a damping effect can be exerted and bending deformation occurring in the building 136 can be suppressed.

  Further, the damper member 16 contracts due to shear deformation generated in the building 136, and the damper member 16 contracts also due to bending deformation generated in the building 136. Therefore, the deformation direction of the damper member 16 becomes the same. Therefore, the deformation of the damper member 16 due to the bending deformation occurring in the building 136 does not reduce the deformation amount of the damper member 16 due to the shear deformation occurring in the building 136.

  By these, the shear deformation and bending deformation which generate | occur | produce in the building 136 can be suppressed, and the effect of the damper member 16 which suppresses the shear deformation generated in the building 136 is not reduced by bending deformation. Moreover, the structural safety of the building 136 is improved by suppressing the bending deformation of the building 136 that has been difficult in the past.

  When a horizontal force from the right to the left is applied to the building 136, the vibration suppression mechanism 138 disposed on the right side of the core wall 76 causes the horizontal force P from the left to the right to be applied to the building 136. In the case where the vibration damping mechanism 138 disposed on the left side of the core wall 76 is used, the same operation and effect as the vibration damping mechanism 138 disposed on the left side of the core wall 76 are obtained. In the case where the horizontal force P from the left to the right is applied to the building 136, the same operations and effects as those of the vibration control mechanism 138 disposed on the right side of the core wall 76 are obtained.

  Further, since the pillar 74 that follows the core wall 76 has a large amount of axial deformation of the pillar 74 when bending deformation occurs in the building 136, the damper member 16 can be greatly deformed. Therefore, the bending deformation generated in the building 136 can be effectively suppressed.

  In addition, the pillars 28 and 74, the outer pillar 135, the inner pillar 132, the upper beam 22, the upper floor beam 96, the beams 26, 50, and 72, the lower beam 24, and the lower part shown in any of the first to sixth embodiments. The floor beam 98 is a frame constituting the buildings 12, 46, 68, 94, 116 and 136. Therefore, when the building is an S structure as in the first to sixth embodiments, these columns, outer columns, inner columns, upper beams, upper floor beams, beams, lower beams, and lower floor beams are also S structures. If the building is an SRC structure or RC structure, these columns, outer columns, inner columns, upper beams, upper beams, beams, lower beams, and lower beams are also SRC or RC beams. Become. In addition, in the case of a building with a mixed structure of S, SRC, and RC structures, columns, outer columns, inner columns, upper beams, upper floor beams, beams, lower beams, and lower floor beams also have their structures ( S construction, SRC construction, RC construction).

  In addition, the damper member 16 shown in the first to sixth embodiments may be any member that deforms in the axial direction and exhibits a damping effect. For example, an oil damper, a friction damper, a steel damper, a lead damper, or the like is used. May be.

  In addition, the rigid member 18 shown in the first to sixth embodiments may be any member that has rigidity in the axial direction and has little deformation with respect to tensile force and compressive force acting in the axial direction. Steel members made of steel such as H-type and box-type, assembled steel members having an appropriate cross-sectional shape, precast concrete members, cast-in-place concrete members, and the like may be used.

  Further, the connecting beam 100 shown in the fourth embodiment may have any strength as long as the damper member 16 and the rigid member 18 can be held at predetermined positions. For example, a steel frame made of steel such as an H shape or a box shape is used. A member, an assembled steel member having an appropriate cross-sectional shape, a precast concrete member, a cast-in-place concrete member, or the like may be used.

  In addition, the brace member 120 shown in the fifth embodiment and the brace member 140 shown in the sixth embodiment may have any strength that can hold the damper member 16 and the rigid member 18 at predetermined positions. For example, a steel member made of steel such as an H shape or a box shape, an assembled steel member having an appropriate cross-sectional shape, a precast concrete member, or a cast-in-place concrete member may be used.

  In addition, the connecting portions 30, 32, and 34 shown in the first embodiment, the connecting portions 52, 54, and 56 shown in the second embodiment, the connecting portions 78, 80, and 82 shown in the third embodiment, Pin the coupling portions 30, 32, 102 shown in the fourth embodiment, the coupling portions 30, 32, 122 shown in the fifth embodiment, and the coupling portions 142, 144, 146 shown in the sixth embodiment. Although it does not necessarily mean that the pin is physically inserted, the connection method that transmits the axial force of the member to the connection part is considered appropriately in consideration of the cross-sectional shape and length of the member. You just have to decide. Therefore, the member may be rigidly coupled and receive some bending.

  Moreover, although the example which has arrange | positioned the vibration suppression mechanism so that it straddled two levels of a building was shown in 1st-3rd embodiment, the vibration suppression mechanism should just be arrange | positioned so that it may straddle a plurality of levels.

  In the fourth to sixth embodiments, the example in which the vibration control mechanism is arranged in one level of the building is shown. However, the vibration control mechanism is arranged in one level or straddles a plurality of levels. It only has to be arranged.

  In the first to sixth embodiments, the example in which the vibration control mechanism is arranged on all the floors from the first floor to the roof floor of the building is shown. Depending on the effect, the necessary number of vibration control mechanisms may be arranged in the necessary hierarchy.

  For example, the deformation of the lower layer of the building affects the deformation of the upper layer, and the horizontal force received by an earthquake or the like becomes larger in the lower layer. Therefore, a vibration damping mechanism may be provided only in the lower layer, or a vibration damping mechanism having a large capacity damper member may be disposed in the lower layer, and a vibration damping mechanism having a small capacity damper member may be disposed in the upper layer. Good.

  Moreover, the vibration suppression mechanism shown in the first to sixth embodiments is arranged only in a place where the influence of bending deformation of the building is large, and the effect of suppressing the shear deformation of the building is provided in a place where influence of the bending deformation of the building is small. If the conventional vibration damping mechanism that exhibits the above is disposed, the installation efficiency of the damper member can be increased and the cost can be reduced.

  In the first, second, fourth, and fifth embodiments, the support member is the pillar 28 erected on the outer periphery of the building 12, 46, 94, 116. However, the outer periphery of the building 12, 46, 94, 116 is used. It is good also as a pillar standing in the vicinity. The vicinity of the outer periphery of the building 12, 46, 94, 116 means the position inside the building 12, 46, 94, 116 and close to the outer periphery of the building 12, 46, 94, 116.

  In the third and sixth embodiments, the support member is the pillar 74 erected along the core wall 76, but the support member may be the core wall. In this case, the edge of the core wall corresponds to the pillar 74, and the same effect as the pillar 74 is obtained.
