Description

  The present invention relates to a seismic damper connecting tool, a seismic damper, and a seismic structure of a building.

  Conventionally, it is required to improve the earthquake resistance of structures. For example, among RC buildings, the rigid frame structure where the nodes of the columns and beams are rigidly connected has the disadvantage of being easily damaged when an earthquake occurs because of its lack of stickiness and low deformation capacity. It is necessary to take measures to prevent damage from the viewpoint of ensuring the safety of residents etc. against damage. In addition, damage that occurs when an earthquake occurs is relatively easily noticeable, such as cracks that occur in the vicinity of the nodal point between the column and the beam, which also reduces the real estate value of the building. Therefore, it is necessary to take measures not only from ensuring safety but also from the viewpoint of preventing real estate value reduction.

Conventionally, as an earthquake countermeasure for this type of RC system building, for example, as described in Patent Document 1 described later, an interlayer displacement between an upper beam and a lower beam in a frame composed of columns and beams A vibration control method that attenuates vibrations and suppresses deformation by absorbing vibration energy using a vortex is adopted.
In Patent Document 1, a friction damper (vibration energy absorbing mechanism) for a seismic device is incorporated in a frame, and the vibration energy is absorbed by the friction damper for the seismic device, thereby suppressing the deformation of the RC building and suppressing deformation. ing.

JP 2002-115418 A (FIG. 14 and the like)

However, in this method, the performance cannot be expected in many cases depending on the joint strength of the friction damper for the earthquake-resistant device to the building frame.
For example, when installing a seismic device friction damper to an existing RC structure housing, the seismic device friction damper cannot be directly connected to the aggregate of the housing. For this reason, the friction damper for an earthquake-resistant device is generally fixed by an anchor driven into a concrete frame, but it is difficult to obtain sufficient connection strength with such a connection form. In particular, since concrete is fragile with respect to tensile force, it has sufficient connection strength against the force that is relatively away from the connection with the housing (ie, the force that peels the friction damper for seismic devices from the housing). It was difficult to get.
If the connection strength is low in this way, the force is not easily transmitted to the friction damper for the seismic device, and the absorption of vibration energy due to the operation of the damper is reduced, so that the performance of the friction damper for the seismic device cannot be fully exhibited. .

In addition, in order to sufficiently secure the connection strength between the frame and the friction damper for the earthquake-resistant device, it is necessary to employ a complicated connection structure or a large-scale connection structure, and accordingly, the connection structure is enlarged.
When the connection structure is increased in size as described above, there is a problem that the space in the frame is blocked by installing the friction damper for the earthquake-proof device in the frame. In other words, the space formed between the columns is partitioned by the friction damper for the earthquake-resistant device, and there is an inconvenience that the space cannot be used in a wide state. As a result, the functionality and landscape of the internal space of the building are also impaired.
Moreover, since a complicated connection structure or a large-scale connection structure is adopted as a connection structure between the frame and the friction damper for the earthquake-resistant device, it takes time to install the friction damper for the earthquake-resistant device, so that the construction period is prolonged.
In addition, the problem derived from the connection strength of such a frame and the friction damper for seismic devices is not limited to the RC-type building but also applies to, for example, a wooden building using a shaft construction method.

  The present invention has been made in view of the above-described circumstances, and can sufficiently exhibit the performance of the vibration control damper, can be installed without blocking the space, and does not require large-scale reinforcement work or the like. The purpose of the present invention is to provide a damping damper connector, a damping damper, and a damping structure of a building that can easily install a damping damper in an existing building with a short construction period.

In order to solve the above-mentioned problems, the following means are adopted for the seismic damper connecting tool, the seismic damper, and the seismic structure of the building of the present invention.
That is, vibration control damper connector according to the present invention, there is provided a connector for connecting the vibration control damper body relative skeleton building, attached to the skeleton, the vibration control damper body, the a support base for supporting and allowing relative displacement in a direction away from the building frame, has a spacing means that will be interposed between the support base and the vibration control damper body, said spacing means, An interval between the support base and the vibration control damper main body at the intervening position is allowed to increase while the decrease in the distance is restricted, and the distance holding device includes the support base and the vibration control damper main body. And a wedge member into which the tip is inserted .

In this seismic damper connecting tool, the support base supports the seismic damper main body so as to be relatively displaceable in a direction away from the building frame.
For this reason, if the seismic damper body connected to the chassis by this seismic damper connector is deformed due to vibration in the chassis , and the deformation causes a force away from the chassis, In addition, since the relative displacement is easily performed in a direction away from the support base, a tensile force is not applied to the connection portion between the support base and the housing or only a very small tensile force is applied.

On the other hand, when the damping damper main body is displaced in the direction away from the support base in this way, the interval holding device regulates the decrease in the distance between the support base and the damping damper main body, and the damping damper main body and the support base The play in between is eliminated.
Thus, the vibration control damper body, when a force of a direction close to the building frame with the deformation of the precursor by vibration is applied immediately to the vibration control damper body force from the building frame via the vibration control damper connector The vibration control body is actuated by the transmission and the vibration energy is absorbed quickly.
Here, when the force in the direction close to the housing acts on the damping damper main body in this way, a compressive force is applied to the connection portion between the support base and the housing. Concrete building frame is strength against compression is high, it is hard to be elastically deformed by the compressive force, it is possible to force the skeleton is transmitted effectively Seismic damper body, Seismic of Seismic Damper body The ability can be fully demonstrated.

Further, as described above, although a compressive force is applied to the connection portion between the support base and the housing, a tensile force is hardly applied, so that the connection strength between the support base and the housing is lower than that in the prior art. For this reason, it is possible to simplify the connection structure between the vibration damper connecting member and the housing.
Here, this damping damper connecting tool is used to connect the damping damper body to the RC system structural frame, as well as a wooden structure using the shaft construction method, and the damping damper to the frame of other structures. It can be used to connect the main body .

Also, the vibration control damper connecting device, wherein the spacing means is, that has a wedge member is inserted the tip against between the support base and the vibration control damper body.

In the vibration damping damper connecting device configured as described above, the support base receives the vibration damping damper main body via the wedge member, and the wedge member regulates a reduction in the distance between the support base and the vibration damping damper main body. Thus, the play between the damping damper main body and the support base is eliminated.

In this seismic damper connecting tool, the wedge member may have a tip inserted from above between the support base and the seismic damper main body .

In the damping damper connector configured in this way, when the damping damper main body is displaced in a direction away from the support base and the gap between the support base and the damping damper main body widens, the wedge member has its own weight. To enter this gap.
Thereby, the reduction | decrease of the space | interval of a support stand and a damping damper main body is controlled, and the play between a damping control damper main body and a support stand is eliminated.
Here, the seismic damper connecting tool having this configuration may be provided with a drop-off prevention device that holds the wedge member from above to prevent the drop-off from between the support base and the damper main body.

Further, spacing means, the wedge member may be configured to have a biasing member for biasing the distal direction.

In the vibration damping damper connecting device configured as described above, the support base receives the vibration damping damper main body via the wedge member. The wedge member is urged (pressed) toward the distal end by the urging member.
For this reason, when the damping damper body is displaced away from the support base and the gap between the support base and the damping damper body widens, the wedge member is pushed into the gap by the biasing force of the biasing member. It is.
Thereby, the reduction | decrease of the space | interval of a support stand and a damping damper main body is controlled, and the play between a damping control damper main body and a support stand is eliminated.

  A seismic damper according to the present invention is a seismic damper that is connected to a housing of a building, a damper main body that absorbs vibration energy, and a vibration damper connecting tool that connects the damper main body to the housing. And the damping damper connector according to any one of claims 1 to 3 is used as the damping damper connector.

In the seismic damper configured as described above, the support base is configured to support the damper main body so as to be relatively displaceable in a direction away from the building body.
For this reason, when the deformation due to vibration occurs in the housing, and a force in the direction away from the housing is applied to the damper main body along with the deformation, the damper main body is easily relative to the direction away from the housing and the support base. Since it is displaced, a tensile force is not applied to the connecting portion between the support base and the housing or only a very small tensile force is applied.

On the other hand, when the damper main body is displaced in a direction away from the support base in this way, the interval holding device restricts the decrease in the distance between the support base and the damper main body, and the play between the damper main body and the support base is eliminated. The
As a result, when a force in the direction approaching the housing is applied to the damper main body due to deformation of the housing due to vibration, the force from the housing is immediately transmitted to the damper main body via the vibration damping damper connecting device. The body is activated and vibration energy is absorbed quickly.
Here, when a force in a direction close to the housing acts on the damper main body in this way, a compressive force is applied to the connection portion between the support base and the housing. The concrete frame has high strength against compression and is not easily elastically deformed even if it receives compression force, so the force from the frame is effectively transmitted to the damper body, and the damping capacity of the damping damper is sufficient. Can be demonstrated.

Further, as described above, although a compressive force is applied to the connection portion between the support base and the housing, a tensile force is hardly applied, so that the connection strength between the support base and the housing is lower than that in the prior art. For this reason, it is possible to simplify the connection structure between the vibration damper connecting member and the housing.
Here, the damping damper can be used not only for damping the RC structure structure but also for damping a wooden structure or other structure using a frame construction method.

  In this seismic damper, the damper main body may be a buckling-restrained damper.

The buckling-restrained damper has a high vibration energy absorbing ability even at the same scale as compared with a general vibration energy absorbing mechanism such as a viscous damping damper. That is, the buckling-restrained damper can be smaller than a general vibration energy absorption mechanism when the required vibration energy absorption capability is at the same level.
In the seismic damper according to the present invention, since the damper main body can be small, the installation space can be reduced and the effective space in the building can be increased.

  The seismic structure of a building according to the present invention is a seismic control structure of a building including columns and beams that are connected to each other, and a bending caused by the seismic force of one of the columns and beams. An arm provided near an intermediate position in the axial direction where the direction of the moment is switched, and the other of the column and the beam and the arm are attached to the arm, and the displacement of the arm and the other column or beam of the other during the earthquake A vibration energy absorbing mechanism that operates by relative displacement due to deformation, and the vibration damping damper according to claim 4 is used as the vibration energy absorbing mechanism.

  When a horizontal seismic force acts on a building composed of columns or beams due to the occurrence of an earthquake, the columns and beams are deformed while maintaining the perpendicularity of their joints. At this time, the bending moment generated in the column and the beam is reversed at the nodes at both ends thereof, and becomes larger toward the end. Also, the bending moment becomes zero at an intermediate position in the axial direction of the beam and column, and the direction is switched at that position. In addition, the deformation angle is maximized at that position, and the rotational displacement is also maximized.

  According to the seismic structure of this building, the arm provided at or near the position where the direction of the bending moment changes in either the column or the beam is greatly rotated and displaced by deformation during the earthquake. The vibration energy absorption mechanism is moved by the rotational displacement and the relative displacement caused by the deformation of the other column or beam, and vibration can be effectively suppressed by absorbing the vibration energy. In addition, the vibration energy absorption mechanism applies a force to the arm in a direction that prevents rotational displacement. As a result, a bending moment acts on the column or beam to which the arm is attached. Since the total bending moment acting on the beam is kept small, it is not necessary to perform reinforcement or the like.

And in this earthquake-resistant structure of the building, as the vibration energy absorbing mechanism, the vibration energy is rapidly absorbed and the vibration damper having a high vibration control capacity is used, so that the earthquake resistance is excellent.
Particularly, since the damping damper according to claim 4 is small, when this damping damper is used as a vibration energy absorbing mechanism, a large effective space in the building can be taken, and the function in the building can be increased. You can keep the sex and landscape.
Here, the seismic structure of the building can be applied to a wooden structure using a frame construction method and other structures in addition to an RC structure.

According to the vibration control damper connector, the vibration control damper, and the earthquake resistant structure of the present invention, the force from the building frame can be quickly and effectively transmitted to the vibration control damper body. The main body 's vibration control capability can be fully demonstrated.
In addition, since the connection structure between the vibration damper connecting member and the frame can be simplified, the connection structure can be small and can be installed without blocking the space in the building.
Furthermore, since the connection structure is simple, it is easy to attach the damping damper main body to the frame, and the damping damper main body can be attached to the building in a short construction period regardless of whether it is newly installed or existing.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 shows a seismic structure 1 for a building according to the present invention. In the present embodiment, an example is shown in which the present invention is applied to an RC system building 2 having a rigid structure in which a column 3 and a beam 4 are rigidly joined.
Here, in order to simplify the description, for example, as shown in FIG. 1, a case where the present invention is applied to a rigid frame 2 composed of two columns 3 and beams 4 will be described. In particular, the earthquake-resistant structure 1 according to the present embodiment is applied to a frame structure on which a horizontal seismic load F acts as shown in FIG.

  As shown in FIG. 1, the seismic structure 1 according to this embodiment includes an arm 5 provided on a beam 4, and a seismic damper disposed between a tip of the arm 5 and two pillars 3. 6 (vibration energy absorption mechanism). Here, the arm 5 is a member extending in a cantilever shape vertically downward from the lower surface of the beam 4.

  When a horizontal seismic load F is applied, a bending moment is applied to the rigid frame 2. The bending moment acting on the beam 4 becomes zero at an intermediate position A in the axial direction of the beam 4 and acts in opposite directions on both sides thereof. The magnitude of the bending moment changes linearly in the longitudinal direction and increases at both ends of the beam 4.

  In the earthquake-resistant structure 1 according to the present embodiment, the arm 5 is fixed at a position A where the bending moment of the beam 4 is almost zero. In other words, this position A is also a position where the direction of the bending moment is switched along the axial direction of the beam 4 and is an inflection point of deformation of the beam 4 shown in FIG. This position A can be obtained by calculation, and in the case of an existing building, can be known from a design calculation sheet.

The vibration damper 6 includes a damper main body 7 that absorbs vibration energy, and a vibration damper connecting tool 8 that connects the end of the damper main body 7 to the column 3 or the arm 5.
As the damper main body 7, for example, a viscoelastic damper using the viscosity of a viscoelastic body, a viscous damping damper such as an oil damper, a hysteresis damping damper using plasticity or friction of a steel material, or the like is used.

  In the present embodiment, a buckling-restrained damper that is a kind of a hysteresis damping damper is used as the damper main body 7. Specifically, as shown in the longitudinal sectional view of FIG. 3A, the damper main body 7 is a core made of a low yield point material, one end of which is attached to the damping damper connector 8 and the other end is attached to the arm 5. A material 11 and a stiffening frame 12 made of a material having a higher yield point than the core material 11 and covering the central portion of the core material 11 are provided. In this embodiment, the core member 11 is a rod-like member having a substantially rectangular shape in cross section, and at one end thereof, as shown in the plan cross-sectional view of FIG. A cross-sectional reduction part 11 ′ is provided for this purpose. The stiffening frame 12 has a hollow quadrangular prism shape in which the dimension of the internal space is slightly larger than the outer dimension of the core material 11.

  The damper main body 7 absorbs vibration energy by yielding the cross-sectionally reduced portion 11 ′ with a force from the end of the core material 11 and plastically deforming it. The stiffening frame 12 restrains the buckling deformation of the core material 11 when a compressive force is applied to the core material 11, and is for making the compression strength of the damper main body 7 equal to the tensile strength.

  The damping damper connecting tool 8 is attached to the column 3 of the RC system building 2 and supports the damping damper main body 7 so that the damping damper main body 7 can be relatively displaced in a direction away from the column 3. And an interval holding device 17 that restricts a decrease in the interval while allowing an increase in the interval between the support base 16 and the damper body 7.

The support base 16 includes a base portion 21 that forms a connection portion with the pillar 3, and a support portion 22 that is spaced apart from the base portion 21 toward the damper main body 7 and receives the core material 11 of the damper main body 7. Yes.
The base 21 is bonded to the column 3 by a grout G and is further fixed to the column 3 by an anchor bolt B.
In the base portion 21, an inclined surface 21 a is provided on the damper body 7 side so as to project toward the damper body 7 side from the upper end toward the lower end.

The upper surface 22a of the support portion 22 is a substantially horizontal surface, and the end portion of the core material 11 of the damper main body 7 is placed on the upper surface 22a.
A clamp plate 23 is bolted above the support portion 22, and the core material 11 is fixed to the support portion 22 with the end portion sandwiched between the support portion 22 and the clamp plate 23. Yes. Here, the end portion of the core material 11 is provided with play in the axial direction with respect to the support portion 22, and the core material 11 can be relatively displaced in a direction away from the base portion 21.

Moreover, the support part 22 is arrange | positioned in the position spaced apart to the damper main body 7 side with respect to the base 21, and as shown in FIG. 4, it connects with the base 21 via the plate-shaped stay 24. As shown in FIG. .
Further, the stay 24 supports a wedge member 26 (described later) inserted between the base portion 21 and the support portion 22 from the side, whereby the wedge member 26 is detached from the vibration damping damper connector 8. Is prevented.

The interval holding device 17 includes a wedge member 26 having a tip inserted from above between the support base 16 and the tip of the core 11 of the vibration damper 6.
The wedge member 26 has a first receiving surface 26 a that receives the inclined surface 21 a of the base portion 21 a on the surface facing the base 21 side, and a second receiving surface that receives the end surface 11 a of the core material 11 on the surface facing the core material 11 side. 26b. Here, the angle formed by the first and second receiving surfaces 26a and 26b is substantially the same as the angle formed by the inclined surface 21a of the base 21a and the end surface 11a of the core member 11 (however, the inclined direction is opposite). The first receiving surface 26a is in surface contact with the inclined surface 21a, and the second receiving surface 26b is in surface contact with the end surface 11a.

  The spacing device 17 is provided with a biasing member 27 that biases (presses) the wedge member 26 toward the distal end. In the present embodiment, the biasing member 27 is configured by a coil spring provided between the lower surface 4 a of the beam 4 and the upper end of the wedge member 26.

The operation of the seismic structure 1 of the present embodiment configured as described above will be described below.
According to the seismic structure 1 according to the present embodiment, when an earthquake load F is applied due to the occurrence of an earthquake, the beam 4 is mainly deformed in the vertical plane as shown in FIG. Since an arm 5 extending vertically downward is fixed to the beam 4, the arm 5 is also rotationally displaced in the vertical plane by deformation of the beam 4.

  In this case, the position A where the bending moment acting on the beam 4 switches along the axial direction of the beam 4 is an inflection point where the sign of the curvature of the beam 4 changes, and the inclination angle with respect to the horizontal direction becomes the largest. Therefore, the arm 5 attached to the position A is rotationally displaced around the horizontal axis perpendicular to the beam 4 at the position A and is largely inclined.

  Since one end of the damping damper 6 is attached to the tip of the arm 5, when the arm 5 is rotationally displaced and the tip of the arm 5 is moved, the distance between the damper connecting members 8 of the damping damper 6 changes. As a result of the compression of the core 11 of the damping damper 6, the vibration energy is absorbed by the plastic deformation of the core 11, and the RC building 2 is damped. Here, as will be described later, when the distance between the damper connectors 8 increases, a tensile force hardly acts on the core material 11 of the vibration damper 6.

  According to the damping structure 1 according to this embodiment, the deformation of the beam 4 due to the seismic load F is taken out as the rotational displacement of the lever 5, and the vibration energy is obtained by alternately compressing the left and right damping dampers 6 by the rotational displacement. Can be absorbed. In this case, a bending moment corresponding to the reaction force received from the damping damper 6 and the length of the lever 5 acts on the attachment position A of the lever 5 to the beam 4, as described above. Since the position A is a position where the bending moment due to the earthquake becomes zero, even if the bending moment is received from the lever 5, the bending moment as a whole is not excessive. If the length of the lever 5 is increased, the amount of displacement is further amplified, so that it is possible to control the vibration more effectively, but a sufficient effect can be obtained even if the length is not so long.

  Accordingly, since the lever 5 can be short, the bending moment applied to the beam 4 can be reduced. As a result, it is not necessary to reinforce the beam 4 with a reinforcing member or the like. That is, since the beam 4 can be easily attached without requiring reinforcement work or the like, it can be easily installed in an existing building with a short construction period.

Moreover, according to the damping structure 1 which concerns on this embodiment, the damping damper 6 can be arrange | positioned along the beam 4, as FIG. 1 shows. Therefore, it can install in the part which does not get in the way, such as a ceiling back and under the floor, and can ensure the functionality and landscape of indoor space. Moreover, since the damping damper 6 is attached to the column 3 and the lever 5 by pin connection, there is an effect that the bending moment generated in the connecting portion can be suppressed.
On the other hand, when the damping damper 6 is installed within the reach of the worker, such as under the floor or above the floor, inspection and maintenance work is facilitated.

  Furthermore, according to the vibration control structure 1 according to the present embodiment, even if the coupling portion between the column 3 and the beam 4 is changed from a rigid connection to a pin structure due to an earthquake exceeding an assumption, the vibration control damper 6 is changed by an angle change due to the rotation. Since it is operated, there is also an advantage that the vibration control function is not lost.

Hereinafter, a specific action of the vibration control damper 6 will be described in detail.
As described above, the damper connector 8 that constitutes the vibration damper 6 is configured to support the damper main body 7 such that the damper main body 7 can be relatively displaced in a direction away from the column 3 of the RC building 2.
For this reason, when the RC building 2 is deformed by vibration and a force in a direction away from the pillar 3 is applied to the damper main body 7 along with the deformation, the damper main body 7 is fixed to the pillar 3 and the support base. Since the relative displacement is easily made in the direction away from 16, a tensile force is not applied to the connection portion between the support base 16 and the column 3, or a very small tensile force is applied.

On the other hand, when the damper main body 7 is displaced in the direction away from the support base 16 in this way, the interval holding device 17 restricts the decrease in the distance between the support base 16 and the damper main body 7, and the damper main body 7 and the support base 16 are Play between is canceled.
Specifically, when the damper main body 7 is displaced in a direction away from the support base 16 and the gap between the support base 16 and the damper main body 7 is widened, the wedge member 26 constituting the interval holding device 17 is It is pushed into this gap by its own weight and the urging force of the urging member 27, and the play between the damper 7 and the support base 16 is eliminated.

Thereby, when the force of the direction which adjoins the pillar 3 with the deformation | transformation of the RC type | system | group building 2 by vibration acts on the damper main body 7, the force from the RC type | system | group building 2 will be the damping damper connection tool 8. The damper body 7 is immediately transmitted to the damper main body 7 via the, and the damper main body 7 is operated, so that the vibration energy is quickly absorbed.
Here, when the force in the direction close to the pillar 3 acts on the damper main body 7 in this way, a compressive force is applied to the connection portion between the support base 16 and the pillar 3. Since the concrete pillar 3 has high strength against compression and is not easily elastically deformed even when subjected to compression force, the force from the RC system building 2 is effectively transmitted to the damper main body 7, and the damping damper 6 seismic control ability can be fully demonstrated.

In addition, as described above, although the compressive force is applied to the connection portion between the support base 16 and the column 3, almost no tensile force is applied. Therefore, the connection strength between the support base 16 and the column 3 is lower than the conventional one. That's it. For this reason, the connection structure of the damping damper connector 8 and the pillar 3 can be simplified.
In addition, since the connection structure between the damping damper connector 8 and the pillar 3 can be simplified as described above, the connection structure can be small and installed without blocking the space in the RC system building 2. It is possible. In the present embodiment, a buckling-restrained damper is used as the damper main body 7, and the damper main body 7 can be small in size, so that a wider effective space in the RC building 2 can be taken.
Moreover, it becomes easy to attach the damping damper 6 to the column 3, and the damping damper 6 can be attached to the RC building 2 in a short construction period regardless of whether it is newly installed or existing.
Moreover, although the example which applied the coil spring to the biasing member 27 was shown in this embodiment, it is not restricted to this, The member which utilizes the elastic force of elastic bodies, such as a disc spring, a leaf | plate spring, and rubber | gum, as a biasing force May be used. Further, a weight may be attached to the wedge member 26 as the urging member 27. In this case, the weight of the weight acts as an urging force to push down the wedge member 27.

Here, in the present embodiment, an example in which the earthquake-resistant structure of the building according to the present invention is applied to an RC system structure is shown, but the earthquake-resistant structure of the building according to the present invention is not limited thereto, For example, the present invention can be applied to a wooden structure using a shaft construction method and other structures.
In the present embodiment, an example is shown in which the arm 5 is provided on the beam 4 extending between the pair of pillars 3 and the damping damper 6 is provided between the arm 5 and each pillar 3. Instead of this, an arm 5 may be provided at an intermediate position in the axial direction of the column 3 extending between the pair of upper and lower beams 4, and the damping damper 6 may be provided between the arm 5 and each beam 4.

Further, the earthquake-resistant structure of the building according to the present invention includes the damping damper 6 in a bracing manner between the upper and lower beams 4 as in the earthquake-resistant structure 51 of the building shown in FIG. 5 and the earthquake-resistant structure 52 shown in FIG. It is good also as a structure which installs and prevents the deformation | transformation of the frame comprised by these pillar 3 and the beam 4. FIG.
The earthquake-proof structure 51 of the building shown in FIG. 5 is provided with a damping damper 6 between a connection portion between the pair of columns 3 and the lower beam 4 and an intermediate position between the columns 3 in the upper beam 4. It is a thing.
In this configuration, a space can be secured in the vicinity of the middle portion of the lower beam 4.
The earthquake-resistant structure 52 of the building shown in FIG. 6 is provided with a damping damper 6 from the connecting portion between one column 3 and the upper beam 4 to the connecting portion between the other column 3 and the lower beam 4. The example which provided the damping damper 6 so that it might cross | intersect with the damping damper 6 from the connection part of one pillar 3 and the lower beam 4 to the connection part of the other pillar 3 and the upper beam 4 Is shown.
