Description

  The present invention relates to a building having a vibration energy absorber.

  Conventionally, a building includes a pair of columns spaced apart, an upper beam and a lower beam that are vertically spaced between the columns, and the upper beam and the lower beam. A wall-shaped member whose upper end is fixed to the upper beam, a container open to the upper side that is fixed to the lower beam and receives the wall-shaped member, and is accommodated in the container, Some include a vibration energy absorber that is in close contact with the wall-like member (see Patent Document 1). The vibration energy absorbing material is made of a viscous material.

  When the building vibrates during an earthquake or strong wind, the upper beam receives a horizontal force and is displaced with respect to the lower beam, so that the wall member moves relative to the container. At this time, vibration energy generated during an earthquake or strong wind is consumed by the viscous resistance generated inside the vibration energy absorbing material. Thus, the vibration energy absorbing material absorbs the vibration energy and reduces the vibration of the building.

Japanese Patent Laid-Open No. 10-2127

  However, since the vibration energy absorbing material is accommodated in the container that receives the wall member, the space around the wall member is narrowed by the vibration energy absorbing material, and the space is effectively used. I can't. In addition, it takes much time and cost to manufacture the container and to fix the container to the lower beam, and the building cannot be constructed economically.

  An object of the present invention is to prevent the space around the wall-shaped member from being narrowed by the vibration energy absorbing material and to make effective use of the space. Another object of the present invention is to make it possible to construct a building economically by not using a container for receiving a wall-like member.

  According to the present invention, the building includes an upper beam and a lower beam that are spaced apart in the vertical direction, and each of the upper beam and the lower beam, each composed of two spaced beam members, A wall-shaped member disposed between the lower beam and the lower beam, with an upper end positioned between the beam members of the upper beam and a lower end positioned between the beam members of the lower beam; Vibration interposed between the lower end portion of the wall-like member and one beam member of the lower beam and between at least one of the lower end portion of the wall-like member and the other beam member of the lower beam. Energy absorbers. Accordingly, the space around the wall-like member between the upper beam and the lower beam is not narrowed by the vibration energy absorbing material, and the space can be used effectively. Further, it is possible to eliminate the need for a container for receiving a wall-like member, which has been required in the past, and to economically construct a building without the need and cost of manufacturing the container and fixing the container to a beam below the container. Make it buildable.

  The building according to the present invention includes a pair of pillars spaced in the first horizontal direction, an upper beam and a lower beam provided between the pillars in a vertical direction. An upper beam and a lower beam, each of which is made up of two beam members that connect the columns, and are spaced apart in a second horizontal direction orthogonal to the first horizontal direction, the upper beam and the lower beam A wall-like member disposed between the upper beam and the upper beam and fixed to the upper beam, and the lower end between the beam members of the lower beam. A wall-like member in which the lower end moves with respect to the lower beam when the upper beam receives the first horizontal force when the wind or wind is strong, and the lower end and the lower part of the wall-like member Between one beam member of the other beam and between the lower end portion of the wall-like member and the other beam member of the lower beam. Interposed one in Kutomo, and a vibration energy absorbing material for absorbing vibrational energy generated during seismic or strong wind.

  The vibration energy absorbing material is made of an elastic body or a viscoelastic body. When the building vibrates during an earthquake or strong wind, the upper beam receives the first horizontal force and is displaced relative to the lower beam. Thereby, the lower end portion of the wall-shaped member moves with respect to the lower beam. At this time, the vibration energy absorbing material is sheared to consume the vibration energy. Thus, the vibration energy absorbing material absorbs the vibration energy and reduces the vibration of the building.

  The vibration energy absorbing material is between the lower end portion of the wall member and one beam member of the lower beam and between the lower end portion of the wall member and the other beam member of the lower beam. Since it is interposed in at least one, the space around the wall-shaped member is not narrowed by the vibration energy absorbing material between the upper beam and the lower beam. Therefore, the space around the wall member is not narrowed by the vibration energy absorber as in the conventional case where the vibration energy absorber is housed in a container that receives the wall member. It can be used effectively.

  Further, the vibration energy absorbing material is between the lower end portion of the wall-like member and one beam member of the lower beam and between the lower end portion of the wall-like member and the other beam member of the lower beam. Since the vibration energy absorbing material is interposed in at least one of them, the container is not required as in the conventional case where the vibration energy absorbing material is accommodated in the container that receives the wall-shaped member. For this reason, the said building can be constructed | assembled economically, without requiring the effort and expense which manufacture the said container and fix to the beam below the said container.

  The wall-shaped member may have an opening. The opening is used as a window. The vibration energy absorbing material is between the lower end portion of the wall member and one beam member of the lower beam and between the lower end portion of the wall member and the other beam member of the lower beam. Since it is interposed in at least one, the range in which the opening exists between the upper beam and the lower beam can be expanded vertically without being restricted by the vibration energy absorbing material. Thereby, many lights can be taken in the inside of the said building through the said opening part, and the lighting of the said building can be improved.

  The lower end of the wall-like member is attached to the lower beam by at least one attachment means so as to be movable in the length direction of the lower beam. The mounting means includes an L-shaped member having a substantially L-shaped cross section comprising a vertical portion disposed adjacent to the wall-shaped member and a horizontal portion disposed on the lower beam, and the L-shaped member. A first through hole provided in the vertical portion, a second through hole provided in the horizontal portion of the L-shaped member, and a first inserted into the first through hole and fixed to the wall member. An anchor bolt, a second anchor bolt inserted into the second through hole and fixed to the lower beam, a first nut screwed to the first anchor bolt, and a second nut bolt And one of the first through hole and the second through hole is a long hole extending in a direction perpendicular to the cross section of the L-shaped member.

  Since one of the first through hole and the second through hole is the long hole, the lower end portion of the wall-shaped member can move in the length direction of the lower beam with respect to the lower beam. It is. For this reason, when the upper beam receives the force in the first horizontal direction during an earthquake or a strong wind, the lower end portion of the wall-shaped member is not prevented from moving with respect to the lower beam. .

  When the lower end portion of the wall member is attached to the lower beam by the attachment means, a compressive force is applied to the vibration energy absorbing material by the lower end portion and the lower beam of the wall member. . The attachment means prevents the lower end portion of the wall-like member from moving in the second horizontal direction with respect to the lower beam, and maintains the state in which the compressive force is applied to the vibration energy absorbing material. . For this reason, when the upper beam receives the first horizontal force during an earthquake or strong wind and the lower end of the wall member moves relative to the lower beam, the lower end is vibrated. The vibration energy absorbing material can surely undergo shear deformation without sliding with respect to the energy absorbing material or without sliding the vibration energy absorbing material with respect to the lower beam. Thereby, the vibration energy can be effectively absorbed.

  The building according to the present invention includes a pair of pillars spaced in the first horizontal direction, and at least three beams provided in the vertical direction between the pillars, each of the beams being the first At least three beams each composed of two beam members that are spaced apart from each other in the second horizontal direction orthogonal to the horizontal direction and that connect the columns, and the uppermost beam among the three beams adjacent to each other. A first wall having a top end between the beam members of the uppermost beam and fixed to the uppermost beam, and a lower end portion between the beam members of the intermediate beam. When the uppermost beam receives the first horizontal force during an earthquake or strong wind, the lower end of the member is adjacent to the first wall member that moves relative to the intermediate beam. Among the three beams, it is arranged between the intermediate beam and the lowermost beam, and the upper end is the intermediate beam. A second wall member between the beam members and fixed to the intermediate beam and having a lower end portion between the beam members of the lowermost beam, and the intermediate beam is the first horizontal during an earthquake or strong wind A second wall member that moves relative to the lowermost beam when receiving a force in a direction, and each of the first wall member and the second wall member includes the upper end A notch portion opened upward and provided at the lower end portion, and an extended portion extending downward from the lower end portion provided at the lower end portion, and the extended portion of the first wall member is the The first wall-shaped member is received in the notch portion of the second wall-shaped member and between the lower end portion and the elongated portion of the first wall-shaped member and one beam member of the intermediate beam. At least one of the lower end portion and the extended portion of the beam and the other beam member of the intermediate beam , Vibration energy absorbing material to absorb vibration energy generated at the time of earthquake or strong wind is interposed.

  Since the extended portion of the first wall-shaped member is received by the notched portion of the second wall-shaped member, the second wall-shaped member is below the first wall-shaped member. The range in which the vibration energy absorbing material is present can be expanded below the lower end of the first wall member. Since the vibration energy absorbing material is interposed not only between the lower end portion of the first wall-shaped member and the beam member, but also between the elongated portion and the beam member, the vibration energy absorbing material is The existing range is relatively wide and can absorb the vibration energy more effectively.

  According to the present invention, the vibration energy absorbing material is between the lower end portion of the wall member and one beam member of the lower beam and between the lower end portion of the wall member and the other beam of the lower beam. Since it is interposed in at least one of the beam members, a space around the wall-shaped member is not narrowed by the vibration energy absorbing material between the upper beam and the lower beam. Therefore, the space around the wall member is not narrowed by the vibration energy absorber as in the conventional case where the vibration energy absorber is housed in a container that receives the wall member. It can be used effectively.

  Further, the vibration energy absorbing material is between the lower end portion of the wall-like member and one beam member of the lower beam and between the lower end portion of the wall-like member and the other beam member of the lower beam. Since the vibration energy absorbing material is interposed in at least one of them, the container is not required as in the conventional case where the vibration energy absorbing material is accommodated in the container that receives the wall-shaped member. For this reason, the said building can be constructed | assembled economically, without requiring the effort and expense which manufacture the said container and fix to the beam below the said container.

  As shown in FIGS. 1 and 2, a building 10 is constructed. The building has a pair of pillars 12 spaced in the first horizontal direction (the left-right direction in FIG. 1) and an upper and lower part between the pillars. It includes an upper beam 14 and a lower beam 16 that are spaced apart in a direction, and a wall-like member 18 disposed between the upper beam 14 and the lower beam 16.

  Each of the upper beam 14 and the lower beam 16 includes two beam members 20a and 20b spaced from each other in a second horizontal direction (depth direction in FIG. 1) orthogonal to the first horizontal direction. The member connects the columns 12. As shown in FIG. 2, the floor slab 22 is connected to one beam member 20a. Instead of the example shown in FIG. 2 in which the floor slab 22 is connected to one beam member 20a, the floor slab 22 may be connected to each beam member 20a, 20b. Each of the column 12, the upper beam 14, and the lower beam 16 is made of reinforced concrete.

  The wall-shaped member 18 has an upper end portion 24 and a lower end portion 26. The thickness of the wall-shaped member 18 coincides with the second horizontal direction. The upper end 24 of the wall-shaped member 18 is positioned between the beam members 20 a and 20 b of the upper beam 14 and is fixed to the upper beam 14. The lower end portion 26 of the wall-shaped member 18 is located between the beam members 20a and 20b of the lower beam 16, and when the upper beam 14 receives the first horizontal force during an earthquake or strong wind, Move relative to beam 16. The wall-shaped member 18 is made of precast concrete in the example shown in FIG. 1, but may be made of metal instead.

  The upper end portion 24 of the wall-shaped member 18 is fixed to the upper beam 14 by a plurality of rod-shaped members 28 spaced in the first horizontal direction. Each bar-shaped member 28 passes through the upper end 24 of the wall-shaped member 18 in the thickness direction of the wall-shaped member 18 and is fixed to the upper beam 14. As shown in FIG. 2, each of the beam members 20 a and 20 b of the upper beam 14 and the upper end portion 24 of the wall-shaped member 18 is provided with a through hole 30 that receives the rod-shaped member 28. Each rod-shaped member 28 includes a bolt 32 inserted into a through-hole 30 provided in the beam members 20a and 20b of the upper beam 14 and a through-hole 30 provided in the upper end portion 24 of the wall-shaped member 18, and the bolt And a nut 34 that is screwed together.

  The building 10 has a vibration energy absorbing material 36 interposed between the lower end portion 26 of the wall-shaped member 18 and one beam member 20a of the lower beam 16 (FIG. 2). The vibration energy absorber 36 absorbs vibration energy generated during an earthquake or a strong wind.

  The vibration energy absorber 36 is made of an elastic body or a viscoelastic body. For example, the vibration energy absorbing material 36 can be made of a so-called high-damping rubber produced by blending natural rubber or isoprene rubber with carbon black or silica. The vibration energy absorber 36 can be made of a viscoelastic body containing an acrylic polymer. The vibration energy absorber 36 undergoes shear deformation when the upper beam 14 receives the first horizontal force and the lower end portion 26 of the wall-shaped member 18 moves relative to the lower beam 16 during an earthquake or strong wind. To absorb the vibration energy. The vibration energy absorbing member 36 is fixed to at least one of the lower end portion 26 of the wall-shaped member 18 and one beam member 20 a of the lower beam 16.

  When the vibration energy absorbing member 36 is fixed only to the lower end portion 26 of the wall-shaped member 18, the vibration energy absorbing member 36 is a wall in which the upper beam 14 receives the first horizontal force during an earthquake or a strong wind. When the lower end portion 26 of the shaped member 18 moves relative to the lower beam 16, the vibration energy may be absorbed by receiving frictional resistance from one beam member 20 a of the lower beam 16. When the vibration energy absorbing member 36 is fixed only to one beam member 20a of the lower beam 16, the vibration energy absorbing member 36 has the first horizontal direction force applied to the upper beam 14 during an earthquake or a strong wind. Accordingly, the vibration energy may be absorbed by receiving frictional resistance from the lower end portion 26 of the wall-shaped member 18 when the lower end portion 26 of the wall-shaped member 18 moves relative to the lower beam 16.

  The building 10 replaces the example shown in FIG. 2 with the vibration energy absorbing material 36 interposed between the lower end portion 26 of the wall-shaped member 18 and one beam member 20 a of the lower beam 16. A vibration energy absorbing material (not shown) interposed between the lower end portion 26 and the other beam member 20b of the lower beam 16 may be included. Further, the building 10 is formed between the lower end portion 26 of the wall-shaped member 18 and one beam member 20a of the lower beam 16, and between the lower end portion 26 of the wall-shaped member 18 and the other beam member 20b of the lower beam 16. It is possible to have a vibration energy absorbing material (not shown) interposed between the two.

  When the building 10 vibrates during an earthquake or strong wind, the upper beam 14 receives the first horizontal force and is displaced with respect to the lower beam 16. As a result, the lower end portion 26 of the wall-shaped member 18 moves relative to the lower beam 16. At this time, the vibration energy is consumed by the shear deformation of the vibration energy absorber 36. In this way, the vibration energy absorbing member 36 absorbs the vibration energy and reduces the vibration of the building 10.

  Since the vibration energy absorbing member 36 is interposed between the lower end portion 26 of the wall-shaped member 18 and one beam member 20a of the lower beam 16, the wall-shaped member 18 between the upper beam 14 and the lower beam 16 is used. The space around is not narrowed by the vibration energy absorber 36. For this reason, the container opened upward for receiving the wall-shaped member is fixed to the lower beam, and the space around the wall-shaped member is the same as in the conventional case where the vibration energy absorbing material is accommodated in the container. The space around the wall-shaped member 18 can be used effectively without being narrowed by the vibration energy absorbing material.

  Further, since the vibration energy absorbing material 36 is interposed between the lower end portion 26 of the wall-shaped member 18 and one beam member 20a of the lower beam 16, the container opened upward for receiving the wall-shaped member is a lower beam. The container is not required as in the conventional case where the vibration energy absorbing material is housed in the container. For this reason, it is possible to construct the building 10 economically without requiring the labor and cost of manufacturing the container and fixing the container to the lower beam.

  The wall-shaped member 18 has an opening 38 as shown in FIG. The opening 38 is used as a window. Since the vibration energy absorbing member 36 is interposed between the lower end portion 26 of the wall-shaped member 18 and one beam member 20a of the lower beam 16, an opening 38 is formed between the upper beam 14 and the lower beam 16. The existing range can be expanded in the vertical direction without being restricted by the vibration energy absorber 36. Thereby, many lights can be taken in the inside of the building 10 through the opening part 38, and the lighting of the building 10 can be improved. The wall-shaped member 18 may be one that does not have the opening 38 instead of the example shown in FIG.

  In the example shown in FIGS. 3 and 4, the lower end portion 26 of the wall-shaped member 18 is attached to the lower beam 16 by at least one attachment means 40 so as to be movable in the length direction of the lower beam. The lower end portion 26 of the wall-like member 18 may be attached to the lower beam 16 by a plurality of attachment means 40 spaced in the first horizontal direction, or the lower beam 16 may be attached by one attachment means 40. It may be attached to.

  The attachment means 40 includes an L-shaped member 46 having a substantially L-shaped cross section comprising a vertical portion 42 disposed adjacent to the wall-shaped member 18 and a horizontal portion 44 disposed on the lower beam 16, and the L-shaped member 46. The first through hole 48 provided in the vertical portion 42 of the shape member, the second through hole 50 provided in the horizontal portion 44 of the L shape member 46, and the first through hole 48 are inserted into the wall-shaped member 18. A first anchor bolt 52 to be fixed, a second anchor bolt 54 inserted into the second through-hole 50 and fixed to the lower beam 16, a first nut 56 screwed into the first anchor bolt 52, The second nut 58 is screwed into the second anchor bolt 54. The L-shaped member 46 is made of angle steel, for example.

  One of the first through hole 48 and the second through hole 50 is a long hole extending in a direction perpendicular to the cross section of the L-shaped member 46. In the example shown in FIG. 4, the attachment means 40 has a circular first through hole 48 and the second through hole 50 is the elongated hole. Instead, the first through hole 48 is the elongated hole. Yes, the second through hole 50 may be circular. Since one of the first through hole 48 and the second through hole 50 is the long hole, the lower end portion 26 of the wall-shaped member 18 is movable with respect to the lower beam 16 in the length direction of the lower beam. It is. For this reason, it is not hindered that the lower end portion 26 of the wall-shaped member 18 moves relative to the lower beam 16 when the upper beam 14 receives the first horizontal force during an earthquake or a strong wind. .

  A first anchor bolt hole (not shown) to which the first anchor bolt 52 is fixed and a second anchor bolt hole (not shown) to which the second anchor bolt 54 is fixed are respectively provided on the wall-shaped member 18 and the lower side. It is provided on the beam 16. When attaching the lower end portion 26 of the wall-shaped member 18 to the lower beam 16 by the mounting means 40, first, the L-shaped member 46, the vertical portion 42 is adjacent to the wall-shaped member 18, and the horizontal portion 44 is the lower beam 16. It arrange | positions on the lower beam 16 so that it may be located on. At this time, the first through hole 48 and the second through hole 50 are aligned with the first anchor bolt hole and the second anchor bolt hole, respectively. Next, the first anchor bolt 52 is inserted into the first through hole 48 and the first anchor bolt hole, and is fixed to the first anchor bolt hole. Further, the second anchor bolt 54 is inserted into the second through hole 50 and the second anchor bolt hole, and fixed to the second anchor bolt hole. Thereafter, the first nut 56 and the second nut 58 are screwed into the first anchor bolt 52 and the second anchor bolt 54, respectively.

  When the lower end portion 26 of the wall-like member 18 is attached to the lower beam 16 by the attaching means 40, a compressive force is applied to the vibration energy absorbing material 36 by the lower end portion 26 of the wall-like member 18 and the lower beam 16. . The attachment means 40 prevents the lower end portion 26 of the wall-shaped member 18 from moving in the second horizontal direction with respect to the lower beam 16, and maintains the state where the compressive force is applied to the vibration energy absorbing material 36. To do. Therefore, when the upper beam 14 receives the first horizontal force and the lower end portion 26 of the wall member 18 moves relative to the lower beam 16 during an earthquake or a strong wind, the lower end of the wall member 18 is moved. It is possible to reliably cause shear deformation in the vibration energy absorbing material 36 without the portion 26 sliding on the vibration energy absorbing material 36 or the vibration energy absorbing material 36 sliding on the lower beam 16. Thereby, the vibration energy can be effectively absorbed.

  5 and 6, instead of the example shown in FIG. 1 in which the upper end 24 and the lower end 26 of the wall-shaped member 18 are flat, the upper ends 24 of the wall-shaped members 18a and 18b An open notch portion 60 is provided, and an extended portion 62 extending downward from the lower end portion is provided at the lower end portion 26 of the wall-shaped member 18.

  The building 10 includes at least three beams 64a, 64b, and 64c provided at intervals in the vertical direction between the columns 12, and the uppermost beam 64a among the three beams 64a, 64b, and 64c adjacent to each other. It includes a first wall member 18a disposed between the intermediate beam 64b and a second wall member 18b disposed between the intermediate beam 64b and the lowermost beam 64c. Each of the uppermost beam 64a, the middle beam 64b, and the lowermost beam 64c includes two beam members 20a and 20b that are spaced apart from each other in the second horizontal direction and each connect the column 12.

  The first wall-shaped member 18a has an upper end 24 between the beam members 20a and 20b of the uppermost beam 64a and is fixed to the uppermost beam 64a, and a lower end portion 26 of the first wall member 18a is a beam member of the intermediate beam 64b. Between 20a and 20b. The lower end portion 26 of the first wall member 18a moves relative to the intermediate beam 64b when the uppermost beam 64a receives the first horizontal force during an earthquake or strong wind. The second wall-shaped member 18b has an upper end 24 between the beam members 20a and 20b of the intermediate beam 64b and is fixed to the intermediate beam 64b, and a lower end portion 26 of the second wall member 18b. Between 20a and 20b. The lower end portion 26 of the second wall-shaped member 18b moves relative to the lowermost beam 64c when the intermediate beam 64b receives the first horizontal force during an earthquake or strong wind.

  Each of the first wall-shaped member 18a and the second wall-shaped member 18b has a thickness direction that coincides with the second horizontal direction, and the upper end 24 and the lower end 26 are opposed to each other in the first direction. A pair of end portions 66 and 68 are provided. Each upper end 24 of the first wall-shaped member 18a is fixed to the uppermost beam 64a by a bar-shaped member 28, and each upper end 24 of the second wall-shaped member 18b has a bar-like shape. The member 28 is fixed to the intermediate beam 64b.

  Each of the first wall-shaped member 18a and the second wall-shaped member 18b includes a cutout portion 60 opened at the upper end portion 24 and opened downward from the lower end portion provided at the lower end portion 26. And an elongated portion 62 that extends. The notched portion 60 has one side portion 70 that is spaced inwardly from one end portion 66 of the upper end portion 24 and the other side portion 70 that is spaced inwardly from the other end portion 66 of the upper end portion 24. And a bottom portion 72 between one side portion 70 and the other side portion 70. The elongated portion 62 has one side portion 74 that is spaced inwardly from one end portion 68 of the lower end portion 26, and the other side portion 74 that is spaced inwardly from the other end portion 68 of the lower end portion 26. , And is defined by a lower end portion 76 between one side portion 74 and the other side portion 74. Each side portion 74 of the lower end portion 26 of the first wall-shaped member 18a is spaced from the side portion 70 of the upper end portion 24 of the second wall-shaped member 18b, and the interval is equal to the lower end of the first wall-shaped member 18a. This corresponds to the distance that the part 26 can move relative to the intermediate beam 64b during an earthquake or strong wind.

  The extended portion 62 of the first wall-shaped member 18a is received in the notched portion 60 of the second wall-shaped member 18b, and one of the lower end portion 26 of the first wall-shaped member 18a and the extended portion 62 and the intermediate beam 64b. The vibration energy absorbing material 36 is interposed between the beam member 20a (FIG. 6). Since the extended portion 62 of the first wall-shaped member 18a is received in the notched portion 60 of the second wall-shaped member 18b, the second wall-shaped member 18b is present below the first wall-shaped member 18a. Therefore, the range in which the vibration energy absorbing material 36 exists can be expanded below the lower end portion 26 of the first wall-shaped member 18a. The vibration energy absorbing member 36 is not only between the lower end portion 26 of the first wall-shaped member 18a and one beam member 20a of the intermediate beam 64b, but also between the extended member 62 and one beam member 20a of the intermediate beam 64b. Therefore, the vibration energy absorbing material 36 is present in a relatively wide range, and the vibration energy can be absorbed more effectively.

  The vibration energy absorbing member 36 is replaced with the first wall 26a instead of the example shown in FIG. 6 interposed between the lower end portion 26 and the extended portion 62 of the first wall member 18a and one beam member 20a of the intermediate beam 64b. May be interposed between the lower end portion 26 and the extended portion 62 of the wall-shaped member 18a and the other beam member 20b of the lower beam 16, or may be interposed between the lower end portion 26 and the extended portion 62 of the first wall-shaped member 18a. It may be interposed between one beam member 20a of the beam 16 and between the lower end portion 26 and the extended portion 62 of the first wall member 18a and the other beam member 20b of the lower beam 16.

  In the example shown in FIGS. 7 and 8, each of the first wall-shaped member 18 a and the second wall-shaped member 18 b includes a cutout portion 60 provided in the upper end portion 24, and an extended portion 62 provided in the lower end portion 26. 5 having an upper extension portion 78 extending upward from the upper end portion, and a lower extension portion extending downward from the lower end portion provided at the lower end portion 26, instead of the example shown in FIG. 80.

  Each of the first wall-like member 18a and the second wall-like member 18b has a first wall-like shape in which the upper end portion 24 and the upper extension portion 78 are thinner and the lower end portion 26 and the lower extension portion 80 are thinner than the intermediate portion 82. In the thickness direction of the member 18a, the center of the lower end portion 26 and the downward extension portion 80 of the first wall member 18a is on the side of one beam member 20a of the intermediate beam 64b from the center of the intermediate portion 82 of the first wall member 18a. In the thickness direction of the second wall member 18b, the center of the upper end portion 24 and the upper extension portion 78 of the second wall member 18b is intermediate from the center of the intermediate portion 82 of the second wall member 18b. The beam 64b is separated from the other beam member 20b. The upper end portion 24 and the upper extension portion 78 of the second wall member 18b are adjacent to the lower end portion 26 and the lower extension portion 80 of the first wall member 18a in the second horizontal direction.

  The vibration energy absorbing member 36 is interposed between the lower end portion 26 and the downward extending portion 80 of the first wall member 18a and one beam member 20a of the intermediate beam 64b. Further, another vibration energy absorbing material 84 is interposed between the lower end portion 26 and the lower extension portion 80 of the first wall member 18a and the upper end portion 24 and the upper extension portion 78 of the second wall member 18b. The other vibration energy absorbing member 84 is made of an elastic body or a viscoelastic body.

When the uppermost beam 64a receives the first horizontal force during an earthquake or strong wind,
The lower end portion 26 and the lower extension portion 80 of the first wall member 18a move with respect to the intermediate beam 64b and the upper end portion 24 and the upper extension portion 78 of the second wall member 18b. At this time, each of the vibration energy absorbing material 36 and the other vibration energy absorbing material 84 is shear-deformed and the vibration energy is absorbed. In addition to the vibration energy absorbing material 36, the other vibration energy absorbing material 84 also absorbs the vibration energy, so that the vibration of the building 10 can be effectively reduced.
