Japanese Patent Application Laid-Open No. 11-62316

  By the way, when the first member and the second member receive the horizontal force, each of the first member and the second member may be mainly bent and deformed, or may be mainly sheared and deformed. is there. When each of the first member and the second member is mainly bent and deformed, the vertical displacement of the first member with respect to the second member and the vertical displacement of the second member with respect to the first member, respectively. Is relatively large, and the shearing force that the damper receives from the first member and the second member is relatively large. For this reason, the said damper can receive the said shear force, and can deform | transform effectively, and can reduce the said vibration energy effectively.

  On the other hand, when each of the first member and the second member mainly undergoes shear deformation, the first member is hardly displaced in the vertical direction with respect to the second member, and the second member is the first member. There is almost no displacement in the vertical direction with respect to the member, and the shearing force that the damper receives from the first member and the second member is very small. For this reason, the damper cannot be effectively deformed by receiving the shearing force, and the vibration energy cannot be effectively reduced.

  The object of the present invention is to provide the first member when the first member and the second member, which are spaced apart in the horizontal direction and extend in the vertical direction, receive a horizontal force and the vibration energy acts on them. The vibration energy can be reliably reduced regardless of whether each of the member and the second member is bent or sheared.

  In the present invention, one end portion of the diagonal member is fixed to the other end portion of the damper whose one end portion is fixed to the first member, and the other end portion of the diagonal member is attached to the second member. When the first member and the second member receive horizontal force and vibration energy acts on them, regardless of whether each of the first member and the second member is bent or sheared, The damper can be effectively deformed by receiving external force from the diagonal member. Thereby, the vibration energy can be reliably reduced.

  The building according to the present invention is disposed between a first member and a second member that are spaced apart in the horizontal direction and extend in the vertical direction, and the first member and the second member. A damper fixed to the first member; and a diagonal member having one end fixed to the other end of the damper and the other end attached to the second member.

  When the first member and the second member receive a horizontal force during the earthquake and vibration energy acts on them, and each of the first member and the second member is bent and deformed, the first member is The second member is slightly shifted in the vertical direction with respect to the two members, and the second member is slightly shifted in the vertical direction with respect to the first member. At this time, the diagonal member is slightly displaced in the vertical direction with respect to the first member, and the damper is deformed by receiving a shearing force from the diagonal member and the first member. Thereby, the vibration energy is reduced. In addition, since each of the first member and the second member is bent and deformed, a distance between the other end portion of the damper and an attachment position of the other end portion of the diagonal member with respect to the second member is increased. The diagonal member receives an axial force from the other end of the damper and the second member. At this time, the other end portion of the damper receives an external force in the axial direction from the diagonal member, and a vertical component of the external force acts on the damper. For this reason, even when the vertical component of the external force acts on the damper, the damper undergoes shear deformation, and the vibration energy is reduced.

  When each of the first member and the second member is bent and deformed, the vertical displacement of the first member relative to the second member and the vertical displacement of the second member relative to the first member are compared. The diagonal of the diagonal member relative to the first member is relatively large. For this reason, the shear force that the damper receives from the diagonal member and the first member is relatively large, and the damper can be effectively deformed by receiving the shear force. In addition, the damper can also be subjected to shear deformation when the other end portion of the damper receives an external force in the axial direction from the diagonal member and the vertical component of the external force acts on the damper. For this reason, the vibration energy can be effectively reduced.

  When the first member and the second member receive the horizontal force and each of the first member and the second member undergoes shear deformation, the first member is displaced in the vertical direction with respect to the second member. The second member is hardly displaced in the vertical direction with respect to the first member. For this reason, the displacement of the diagonal material in the vertical direction with respect to the first member is relatively small, and the shear force that the damper receives from the diagonal material and the first member due to this displacement is relatively small. However, since each of the first member and the second member undergoes shear deformation, the distance between the other end portion of the damper and the attachment position of the other end portion of the diagonal member with respect to the second member is increased. As a result, the diagonal member receives an axial force from the other end of the damper and the second member, and the other end of the damper receives an external force in the axial direction from the diagonal member. For this reason, the vertical component of the external force acts on the damper, and the damper undergoes shear deformation. Thereby, the vibration energy is reduced.

  Thus, when the first member and the second member receive the horizontal force during an earthquake, regardless of whether each of the first member and the second member is bent or sheared, The damper can be effectively shear-deformed by receiving an external force from the diagonal member. Thereby, the vibration energy can be reliably reduced.

  The damper includes a first end plate and a second end plate, which are opposed to each other in the horizontal direction and are opposed to each other, and the first end plate coupled to the first member and the one end of the diagonal member. A second end plate coupled to the first end plate and a horizontal end space between the first end plate and the second end plate, the first end plate and the second end plate, respectively. A plurality of rubber sheets parallel to each of the end plates, one outermost rubber sheet being fixed to the first end plate and the other outermost rubber sheet being fixed to the second end plate. A plurality of rubber sheets, an internal plate fixed in parallel to each rubber sheet between two adjacent rubber sheets, and a first through hole penetrating each rubber sheet in its thickness direction And the internal play Extending in the horizontal direction through the second through hole penetrating through the first through hole and the first through hole and the second through hole, and fixed to the first end plate and the second end plate It can have a rod-shaped member.

  The damper is a steel plate perpendicular to a horizontal plane having two ends separated in the horizontal direction, one end of which is coupled to the first member, and the other end to the one end of the diagonal member. The bonded steel plates may be provided with a plurality of through-holes that are provided at intervals in the vertical direction in the central portion of the steel plates and each have an elongated shape extending in the horizontal direction.

  The building is disposed between a first member and a second member which are spaced apart in the horizontal direction and extend in the vertical direction, and the first member and the second member, and one end portion of the building is the first member. A first damper fixed to a member, and a second damper disposed between the first member and the second member, one end of which is fixed to the second member, and having a height different from that of the first damper. The second damper located on the side and an oblique member having one end fixed to the other end of the first damper and the other end fixed to the other end of the second damper may be included.

  The vibration energy absorbing device according to the present invention, which is arranged between two horizontally spaced buildings and absorbs vibration energy acting on the building during an earthquake, has one end fixed to one building. A damper, and a diagonal member having one end fixed to the other end of the damper and the other end attached to the other building.

  When the one building and the other building are subjected to a horizontal force and vibration energy acts on these when the earthquake occurs, the one building and the other building are bent and deformed, and the one building and the In any case where each of the other buildings undergoes shear deformation, the distance between the damper and the mounting position of the diagonal member relative to the other building changes so that the diagonal member is connected to the damper and the other building. Receive axial force from. At this time, the damper receives an external force in the axial direction from the diagonal member, and a vertical component of the external force acts on the damper. Thereby, the damper is shear-deformed and the vibration energy is reduced.

  According to the present invention, one end of the diagonal member is fixed to the other end of the damper whose one end is fixed to the first member, and the other end of the diagonal member is attached to the second member. When the first member and the second member receive a horizontal force and vibration energy acts on them, the first member and the second member are bent and deformed, and the first member and the second member In any case where each of the members undergoes shear deformation, the damper receives an external force in the axial direction from the diagonal member, and the vertical component of the external force acts on the damper. Accordingly, the damper can be effectively sheared and deformed. Therefore, the vibration energy can be reliably reduced regardless of whether each of the first member and the second member is bent or sheared.

The front view of the building which concerns on 7th Example of this invention.

  As shown in FIG. 1, a building 10 is constructed, and the building has a first member 12 and a second member 14 that are spaced apart in the horizontal direction and extend in the vertical direction. The damper 18 is disposed between the second member 14 and one end 16 is fixed to the first member 12. The one end 20 is fixed to the other end 22 of the damper 18 and the other end 24 is the second member. 14 and a diagonal member 26 attached to 14. Each of the first member 12 and the second member 14 is a column made of reinforced concrete.

  A first gusset plate 28 is fixed to the other end 22 of the damper 18, and one end 20 of the diagonal member 26 is fixed to the other end 22 of the damper 18 via the first gusset plate 28. Instead of the example shown in FIG. 1 in which the one end 20 of the diagonal member 26 is fixed to the other end 22 of the damper 18 via the first gusset plate 28, the damper 18 directly does not go through the first gusset plate 28. The other end 22 may be fixed.

  The building 10 is a second gusset plate 30 that is disposed between the first member 12 and the second member 14 and is fixed to the second member 14 and is located at a different height from the damper 18. The other end 24 of the diagonal member 26 is attached to the second member 14 via the second gusset plate 30. As shown in FIG. 1, the second gusset plate 30 may be positioned higher than the damper 18 or may be positioned lower than the damper 18. The diagonal member 26 is, for example, H-shaped steel or groove-shaped steel, and is made of ordinary steel.

  As shown in FIGS. 2 and 3, the damper 18 is a so-called laminated rubber containing lead plugs. The damper 18 is a first end plate 32 and a second end plate 34 which are opposed to each other in the horizontal direction and are opposed to each other by a coupling means 36. A horizontal space is provided between the second end plate 34 coupled to the one end 20 of the diagonal member 26 via the first gusset plate 28, and the first end plate 32 and the second end plate 34. And a plurality of rubber sheets 38 parallel to the first end plate 32 and the second end plate 34, respectively, and between the two adjacent rubber sheets 38, each rubber sheet 38 is arranged in parallel. And an inner plate 40. Each of the first end plate 32, the second end plate 34 and the inner plate 40 is made of steel.

  The first end plate 32 has a plurality of spaced through holes 42, and the coupling means 36 is connected to the outside of the first member 12 with one end fixed to the inside of the first member 12. A bolt 44 extending in the horizontal direction and extending through each through hole 42 on the outer side of the first member 12, and a nut 46 screwed to the other end of the bolt. The first gusset plate 28 is fixed to the second end plate 34.

  One outermost rubber sheet 38 and the other outermost rubber sheet 38 are fixed to the first end plate 32 and the second end plate 34, respectively, and the inner plate 40 is respectively connected to two adjacent rubber sheets 38. It is fixed to. The damper 18 includes a first through hole 48 that penetrates each rubber sheet 38 in the thickness direction, a second through hole 50 that penetrates the internal plate 40 in the thickness direction, a first through hole 48, and a second through hole 50. And a bar-like member 52 that extends in the horizontal direction and is fixed to the first end plate 32 and the second end plate 34. The rod-shaped member 52 is made of lead.

  When the first member 12 and the second member 14 receive a horizontal force during the earthquake and vibration energy acts on them, each of the first member 12 and the second member 14 is mainly bent and deformed as shown in FIG. Or the frame formed by each of the first member 12 and the second member 14 may be mainly bent and deformed. As each of the first member 12 and the second member 14 bends and deforms, the first member 12 slightly shifts up and down with respect to the second member 14, and the second member 14 slightly shifts with respect to the first member 12. Shifts up and down. At this time, the diagonal member 26 is slightly displaced in the vertical direction with respect to the first member 12, and the damper 18 receives a shearing force from the diagonal member 26 and the first member 12. Thereby, the rod-shaped member 52 of the damper 18 is sheared and plasticized, and the vibration energy is reduced. In addition, the bending of each of the first member 12 and the second member 14 changes the distance between the other end 22 of the damper 18 and the second gusset plate 30, so that the diagonal member 26 is the other member of the damper 18. An axial force is received from the end 22 and the second gusset plate 30. At this time, the other end portion 22 of the damper 18 receives an external force in the axial direction from the diagonal member 26, and the vertical component of the external force acts on the damper 18. For this reason, even when the vertical component of the external force acts on the damper 18, the rod-shaped member 52 of the damper 18 is sheared and plasticized. Thereby, the vibration energy is reduced.

  When each of the first member 12 and the second member 14 is bent, the vertical displacement of the first member 12 relative to the second member 14 and the vertical displacement of the second member 14 relative to the first member 12 are compared. Big. Therefore, the vertical displacement of the diagonal member 26 with respect to the first member 12 is relatively large, and the shearing force that the damper 18 receives from the diagonal member 26 and the first member 12 is relatively large. Thereby, the damper 18 can receive the said shear force and can deform | transform effectively. In addition, the damper 18 can also be deformed when the other end portion 22 of the damper 18 receives an external force in the axial direction from the diagonal member 26 and the vertical component of the external force acts on the damper 18. For this reason, the vibration energy can be effectively reduced.

  When the first member 12 and the second member 14 receive the horizontal force during an earthquake, the first member 12 and the second member 14 are mainly bent and deformed, instead of the example shown in FIG. As shown, each of the first member 12 and the second member 14 may mainly undergo shear deformation. In this case, the first member 12 hardly shifts in the vertical direction with respect to the second member 14, and the second member 14 hardly shifts in the vertical direction with respect to the first member 12. For this reason, the vertical displacement of the diagonal member 26 with respect to the first member 12 is relatively small, and the shear force that the damper 18 receives from the diagonal member 26 and the first member 12 due to this displacement is relatively small. However, each of the first member 12 and the second member 14 undergoes shear deformation, whereby the distance between the other end portion 22 of the damper 18 and the second gusset plate 30 changes, so that the diagonal member 26 has the damper 18 other than the damper 18. The axial force is received from the end portion 22 and the second gusset plate 30, and the other end portion 22 of the damper 18 receives an external force in the axial direction from the diagonal member 26. As a result, the vertical component of the external force acts on the damper 18, the rod-like member 52 of the damper 18 is sheared and plasticized, and the vibration energy is reduced.

  As described above, when the first member 12 and the second member 14 receive the horizontal force at the time of the earthquake, regardless of whether each of the first member 12 and the second member 14 is bent or sheared, The damper 18 can be subjected to shear deformation by receiving external force from the diagonal member 26. Thereby, the vibration energy can be reliably reduced.

  In the example shown in FIG. 1, the one end 20 of the diagonal member 26 is attached to the first member 12 via the damper 18, but the one end 20 of the diagonal member 26 is temporarily not connected to the damper 18. When attached to the first member 12, when the first member 12 and the second member 14 receive the horizontal force and the diagonal member 26 receives an axial force from the first member 12 and the second member 14, The first member 12 receives an external force in the axial direction from the diagonal member 26. The external force is relatively large, and the load borne by the first member 12 is relatively large. On the other hand, when the one end 20 of the diagonal member 26 is attached to the first member 12 via the damper 18, the first member 12 and the second member 14 receive the horizontal force and the diagonal member 26 When receiving the axial force from the other end portion 22 of the damper 18 and the second gusset plate 30, the other end portion 22 of the damper 18 receives an external force in the axial direction from the diagonal member 26, and the damper 18 receives the external force in the vertical direction. Since the damper 18 is sheared and deformed by the component, the damper 18 does not strongly resist the vertical component of the external force, and the external force is not easily transmitted from the damper 18 to the first member 12. For this reason, the load which the 1st member 12 bears can be reduced.

  Each of the first member 12 and the second member 14 may be made of steel reinforced concrete or steel instead of the example shown in FIG. 1 made of reinforced concrete. Instead of the example shown in FIG. 1 in which both the first member 12 and the second member 14 are pillars, both the first member 12 and the second member 14 may be earthquake-resistant walls, or the first member 12 and the second member. One of 14 may be a pillar and the other may be a seismic wall.

  The rod-shaped member 52 only needs to be plastically deformable and absorb the vibration energy, and may be made of tin instead of the above example made of lead. The damper 18 may be a so-called high-damping laminated rubber having a vibration energy absorbing performance comparable to that of the laminated rubber with a lead plug, instead of the example shown in FIG. 2 which is a laminated rubber with a lead plug. In this case, the damper 18 includes the first end plate 32, the second end plate 34, the rubber sheet 38, and the internal plate 40, but does not include the rod-shaped member 52.

  The damper 18 may be a so-called steel slit damper as shown in FIG. 6 instead of the example shown in FIG. In this case, the damper 18 has two end portions 54, 56 separated in the horizontal direction, and is provided at a distance in the vertical direction in a steel plate 58 perpendicular to the horizontal plane and a central portion 60 of the steel plate, Each has a plurality of through holes 62 having an elongated shape extending in the horizontal direction. One end 54 of the steel plate 58 is coupled to the first member 12, and the other end 56 of the steel plate 58 is coupled to the one end 20 of the diagonal member 26 via the first gusset plate 28.

  A base plate 64 is fixed to one end portion 54 of the steel plate 58, and the base plate is coupled to the first member 12 by coupling means 66. The base plate 64 has a plurality of spaced through holes 68, and the coupling means 66 is horizontally fixed from the inside of the first member 12 to the outside thereof, one end of which is fixed inside the first member 12. A bolt 70 extending through the through hole 68 on the outside of the first member 12 and a nut 72 screwed to the other end of the bolt. The first gusset plate 28 is fixed to the other end 56 of the steel plate 58.

  When the damper 18 receives the shearing force from the diagonal member 26 and the first member 12 during the earthquake, the steel plate 58 undergoes shear deformation. Further, when the other end 22 of the damper 18 receives the external force from the diagonal member 26 during an earthquake, the vertical component of the external force acts on the damper 18 and the steel plate 58 undergoes shear deformation. Thereby, the vibration energy is reduced.

  In the example shown in FIG. 1, the other end 24 of the diagonal member 26 is attached to the second member 14 without a damper, but instead, in the example shown in FIG. 7, the damper (second damper) is attached. ) 74 and is attached to the second member 14. In this case, in addition to the damper (first damper) 18, the building 10 is arranged between the first member 12 and the second member 14, and the second damper 74 whose one end 76 is fixed to the second member 14. The second damper 74 is located at a different height from the first damper 18.

  The second gusset plate 30 is fixed to the other end 78 of the second damper 74, and the other end 24 of the diagonal member 26 is fixed to the other end 78 of the second damper 74 via the second gusset plate 30. ing. Instead of the second gusset plate 30, the other end 24 of the diagonal member 26 is fixed to the other end 78 of the second damper 74 via the second gusset plate 30. It may be directly fixed to the other end 78 of the second damper 74.

  The second damper 74 is a laminated rubber containing a lead plug. The second damper 74 is a first end plate 32 ′ and a second end plate 34 ′ that are spaced apart in the horizontal direction and are coupled to the second member 14 by a coupling means 36 ′. A second end plate 34 ′ coupled to the end plate 32 ′ and the other end 24 of the diagonal member 26 via a second gusset plate 30, a first end plate 32 ′, and a second end plate 34 ′. And a plurality of rubber sheets (not shown) parallel to the first end plate 32 ′ and the second end plate 34 ′, respectively, adjacent to each other. An internal plate (not shown) disposed in parallel with each rubber sheet is provided between the two rubber sheets. Each of the first end plate 32 ', the second end plate 34' and the inner plate is made of steel.

  The first end plate 32 ′ has a plurality of spaced through holes (not shown), and the coupling means 36 ′ is a second member whose one end is fixed inside the second member 14. 14 is a bolt 44 ′ extending horizontally from the inside to the outside of the second member 14. The bolt 44 ′ passes through each through hole on the outside of the second member 14, and a nut 46 ′ screwed to the other end of the bolt. It consists of. The second gusset plate 30 is fixed to the second end plate 34 '.

  One outermost rubber sheet (not shown) and the other outermost rubber sheet (not shown) are fixed to a first end plate 32 ′ and a second end plate 34 ′, respectively, and the inner plate is These are fixed to two adjacent rubber sheets. The second damper 74 includes a first through hole (not shown) penetrating each rubber sheet in the thickness direction, a second through hole (not shown) penetrating the internal plate in the thickness direction, and the first damper hole. A lead-shaped member (not shown) made of lead, which extends in the horizontal direction through one through hole and the second through hole, and is fixed to the first end plate 32 ′ and the second end plate 34 ′. Have.

  When the first member 12 and the second member 14 are subjected to the horizontal force during the earthquake and the first member 12 and the second member 14 are each bent and deformed, the first member 12 is slightly changed with respect to the second member 14. When the second member 14 is slightly displaced in the vertical direction with respect to the first member 12, the diagonal member 26 is slightly displaced in the vertical direction with respect to the second member 14, and the second damper 74 is inclined. A shearing force is received from the material 26 and the second member 14. As a result, the rod-shaped member of the second damper 74 is plastically deformed by shear deformation, and the vibration energy is reduced. In addition, in each of the case where each of the first member 12 and the second member 14 is bent and the case where each of the first member 12 and the second member 14 is shear-deformed, the other end 22 of the first damper 18 and The distance between the other end portion 78 of the second damper 74 changes and the diagonal member 26 receives axial force from the other end portion 22 of the first damper 18 and the other end portion 78 of the second damper 74. At this time, the other end portion 78 of the second damper 74 receives an external force in the axial direction from the diagonal member 26, and the vertical component of the external force acts on the second damper 74 so that the rod-like member of the second damper 74 is sheared. Deforms and plasticizes. Thereby, the vibration energy is reduced.

  The rod-shaped member only needs to be plastically deformable and absorb the vibration energy, and may be made of tin instead of the above example made of lead. The second damper 74 may be a high-attenuation laminated rubber or a steel slit damper instead of the example shown in FIG. 7 which is a laminated rubber containing lead plugs. When the second damper 74 is a steel slit damper, the second damper 74 includes a steel plate (not shown) perpendicular to a horizontal plane, having two ends separated in the horizontal direction, and a center of the steel plate. Each part has a plurality of through holes (not shown) each having a long and narrow shape extending in the horizontal direction. One end of the steel plate is coupled to the second member 14, and the other end of the steel plate is coupled to the other end 24 of the diagonal member 26. When the second damper 74 receives the shearing force from the diagonal member 26 and the second member 14 during the earthquake, the steel plate undergoes shear deformation. When the other end 78 of the second damper 74 receives the external force from the diagonal member 26 during an earthquake, the vertical component of the external force acts on the second damper 74 and the steel plate undergoes shear deformation. Thereby, the vibration energy is reduced.

  In the example shown in FIG. 8, the building 10 is disposed between the first member 12 and the second member 14 in addition to the first damper 18 and the second damper 74, and one end 80 is connected to the second member 14. The third damper 82 is a fixed third damper 82 located at a lower height than the first damper 18. Further, the building 10 has a diagonal member (first diagonal member) 26 having a lower end portion 20 fixed to the other end portion 22 of the first damper 18 and an upper end portion 24 fixed to the other end portion 78 of the second damper 74. In addition, the second diagonal member 90 includes an upper end portion 84 fixed to the other end portion 22 of the first damper 18 and a lower end portion 86 fixed to the other end portion 88 of the third damper 82. In the example shown in FIG. 8, the upper end portion 24 of the first diagonal member 26 is attached to the second member 14 via the second damper 74, but instead of this, the second upper end portion 24 is not interposed via the second damper 74. The two members 14 may be attached. Further, in the example shown in FIG. 8, the lower end portion 86 of the second diagonal member 90 is attached to the second member 14 via the third damper 82, but instead of this, the third damper 82 is not interposed. It may be attached to the second member 14.

  The building 10 includes a pillar 92 spaced horizontally outward from the first member 12 (left side in FIG. 8), and an upper portion provided between the first member 12 and the pillar 92.

A second damper 74 located at the first end, and a first diagonal member 26 having a lower end 20 fixed to the other end 22 of the first damper 18 and an upper end 24 fixed to the other end 78 of the second damper 74. Including. The building 10 is disposed between the upper half 12a of the first member 12 and the upper half 14a of the second member 14, and one end 80 is fixed to the upper half 14a of the second member 14. A third damper 82 located at a lower height than the first damper 18, an upper end 84 is fixed to the other end 22 of the first damper 18, and a lower end 86 is connected to the other end of the third damper 82. And a second diagonal 90 fixed to the end 88. The diagonal member and the damper are not arranged between the lower half 12b of the first member 12 and the lower half 14b of the second member 14.

  In the example shown in FIG. 10, the building 10 is a fourth damper 100 that is disposed between the first member 12 and the second member 14, and whose one end is fixed to the first member 12. The fifth damper 102 is disposed between the fourth damper 100 located at the same height, the first member 12 and the second member 14, and has one end fixed to the second member 14. A fifth damper 102 located at the same height as the third damper member 104, and a third diagonal member 104 having an upper end fixed to the other end of the fourth damper 100 and a lower end fixed to the other end of the fifth damper 102. Including.

  In this case, as shown in FIG. 11, the first damper 18 is moved from the center of the first member 12 in the second horizontal direction (vertical direction in FIG. 11) perpendicular to the first horizontal direction (left-right direction in FIG. 11). The second damper 74 is separated from the center of the second member 14 in the second horizontal direction to the one side. The fourth damper 100 is separated from the center of the first member 12 to the other side (upward in FIG. 11), and the fifth damper 102 is separated from the center of the second member 14 to the other side.

  In the example shown in FIG. 12, a vibration energy absorbing device 110 that absorbs vibration energy acting on the buildings 106 and 108 during an earthquake is disposed between two buildings 106 and 108 that are spaced apart in the horizontal direction. The vibration energy absorbing device 110 includes a first damper 18 having one end fixed to one building 106 and a second damper positioned at a different height from the first damper 18 having one end fixed to the other building 108. 74 and an oblique member 26 having one end 20 fixed to the other end of the first damper 18 and the other end 24 fixed to the other end of the second damper 74.

  During an earthquake, one building 106 and the other building 108 receive horizontal force, and vibration energy acts on the one building 106 and the other building 108, and each of the one building 106 and the other building 108 is mainly bent. When deformed, one building 106 is slightly shifted in the vertical direction with respect to the other building 108, and the other building 108 is slightly shifted in the vertical direction with respect to one building 106. At this time, the diagonal member 26 is slightly shifted in the vertical direction with respect to each of the one building 106 and the other building 108, and the first damper 18 receives a shearing force from the diagonal member 26 and the one building 106, thereby The damper 74 receives a shearing force from the diagonal member 26 and the other building 108. As a result, each of the first damper 18 and the second damper 74 undergoes shear deformation, and the vibration energy is reduced. In addition, as each of the one building 106 and the other building 108 is bent and deformed, the distance between the first damper 18 and the second damper 74 is changed, and the diagonal member 26 has the first damper 18 and the second damper. 74 receives an axial force. At this time, each of the first damper 18 and the second damper 74 receives an external force in the axial direction from the diagonal member 26, and the vertical component of the external force acts on each of the first damper 18 and the second damper 74. As a result, each of the first damper 18 and the second damper 74 undergoes shear deformation, and the vibration energy is reduced.

  When one building 106 and the other building 108 are subjected to the horizontal force and each of the one building 106 and the other building 108 mainly undergoes shear deformation, the one building 106 moves vertically with respect to the other building 108. The other building 108 is hardly displaced in the vertical direction with respect to the one building 106. Therefore, the vertical displacement of the diagonal member 26 with respect to each of the one building 106 and the other building 108 is relatively small, and the shear force that the first damper 18 receives from the diagonal member 26 and the one building 106 due to this displacement and The shear force that the second damper 74 receives from the diagonal member 26 and the other building 108 is relatively small. However, each of the one building 106 and the other building 108 undergoes shear deformation, so that the distance between the first damper 18 and the second damper 74 changes, and the diagonal member 26 has the first damper 18 and the second damper. 74 receives an axial force. At this time, each of the first damper 18 and the second damper 74 receives an external force in the axial direction from the diagonal member 26, and the vertical component of the external force acts on each of the first damper 18 and the second damper 74. As a result, each of the first damper 18 and the second damper 74 undergoes shear deformation, and the vibration energy is reduced.

  Thus, when one building 106 and the other building 108 are subjected to the horizontal force during an earthquake, the one building 106 and the other building 108 are bent and deformed, and the one building 106 and the other building In any of the cases where each of 108 is subjected to shear deformation, each of the first damper 18 and the second damper 74 can be subjected to shear deformation by receiving an external force from the diagonal member 26. For this reason, the vibration energy can be surely reduced regardless of whether each of the one building 106 and the other building 108 is bent or sheared. In the example shown in FIG. 12, the other end portion 24 of the diagonal member 26 is attached to the other building 108 via the second damper 74, but instead, the other end portion 24 of the diagonal member 26 is second. It may be attached to the other building 108 without using the damper 74.
