  By the way, each building beam with a rigid frame structure (frame) is rigidly joined to the building column at its end by welding, riveting, etc., while bending at a part slightly away from the end reduces bending rigidity. It may be configured to be easily deformed and to prevent its destruction.

  In such a building beam, a pair of building columns is mounted by attaching a braking plate to the upper building beam and a box body that receives the braking plate with a gap to a lower building beam adjacent to the upper building beam below. The relative displacement of the lower building beam with respect to the upper building beam caused by the vibration of the base causes a relative displacement of the box body with respect to the brake plate, and this displacement causes viscous shear to the viscous body contained in the box body When the vibration of a pair of building columns is attenuated and each building beam is easily bent and deformed at a part slightly away from its end as described above, the relative position of the box to the brake plate As the displacement decreases, there is a risk that it will not be possible to effectively attenuate the vibration of the building columns and eventually the structure.

  The present invention has been made in view of the above-mentioned points, and the object of the present invention is to effectively reduce the vibration attenuation of a building column by a vibration control wall arranged in the building wall space, and hence the vibration attenuation of a structure. It is to provide a vibration control structure that can be performed.

  A seismic control structure according to the present invention is defined by a pair of building columns juxtaposed to each other, a pair of building beams juxtaposed by bridging the pair of building columns, and a pair of building columns and building beams. And a vibration control wall that is arranged in the building wall space and attenuates the vibration of a pair of horizontal building columns in the vertical plane of the building wall space. One end is rotatably connected to one of the pair of building columns via a shaft member in a vertical plane of the building wall space, and the damping wall has an upper edge extending in the horizontal direction. In one of the pair of building beams in the section, it is fixedly connected to a part separated from the other building column by more than half of the horizontal interval between the pair of building columns and suspended from one building beam The brake plate placed in the vertical plane of the building wall space and the lower edge that extends horizontally Of the other building beams, the other building beam is fixedly connected to a portion separated from the other building column by a half or more of the horizontal interval between the pair of building columns, and on the inner surface with respect to the outer surface of the brake plate A box that receives the braking plate with a gap, and a viscous body that is accommodated in the box and is disposed in the gap, and the damping wall is perpendicular to the building wall space of the building column. At least viscous shear is generated in the viscous body by relative vibration in the vertical plane of the building wall space of the building wall space of the brake plate against the box body caused by a pair of building beams due to horizontal vibration in the plane. The horizontal vibration in the vertical plane of the building wall space of a pair of building columns is attenuated.

  According to the present damping structure, the upper edge of the brake plate is fixedly connected to a part of the building column that is fixedly connected to a part that is more than half of the horizontal interval between the pair of building columns. One end of each box in the horizontal direction with the other building beam in which the lower edge of the box is fixedly connected to a part separated from the other building column by more than half of the horizontal interval between the pair of building columns Are connected to one of the pair of building columns via a shaft member so as to be rotatable in the vertical plane of the building wall space. It is possible to prevent bending deformation from occurring at one end side portion that is more than half of the horizontal interval from the other building column, and thus to prevent the horizontal deformation of both building beams caused by the vibration of the pair of building columns. Can effectively produce a horizontal relative displacement on one end side of the direction, As a result of preventing the decrease in the viscous shear amount due to the viscous plate of the viscous material contained in the body, it is effective to attenuate the vibration of the building column by the damping wall placed in the building wall space, and hence the vibration of the structure Can be done.

  In such a vibration control structure, the other horizontal end of each of the pair of building beams may be fixedly connected to the other building column of the pair of building columns.

  The vibration control structure according to the present invention is defined by a pair of building columns juxtaposed to each other, a pair of building beams that are bridged together by bridging the pair of building columns, and a pair of building columns and building beams. A pair of horizontal members arranged in the building wall space and arranged in parallel with each other by bridging a pair of building columns, and arranged in the vertical plane of the building wall space while being arranged between the pair of horizontal members And a damping wall that attenuates the vibration of the pair of building columns in the direction, and one horizontal end of each of the pair of transverse members is pivoted to one building column of the pair of building columns The vibration control wall is fixedly connected to one horizontal member of the pair of horizontal members at the upper edge portion extending in the horizontal direction. A brake plate that hangs down from one horizontal member and is arranged in the vertical plane of the building wall space, and a horizontal direction A box that is fixedly connected to the other horizontal member of the pair of horizontal members at a lower edge portion that extends, and that receives the brake plate with a gap on the inner surface with respect to the outer surface of the brake plate; And a viscous body disposed in the gap, and the damping wall is a pair of transverse members due to horizontal vibration in the vertical plane of the building wall space of the building column. The horizontal direction of the pair of building pillars in the vertical plane of the building wall space causes the viscous body to generate at least viscous shear by the relative vibration in the vertical plane of the building wall space of the brake plate with respect to the box body generated via It is designed to attenuate the vibration.

  According to such a vibration control structure of the present invention, the one horizontal member to which the upper edge portion of the brake plate is fixedly connected and the other horizontal member to which the lower edge portion of the box is fixedly connected. Since one end in the horizontal direction of each of the two is rotatably connected to one of the pair of building columns via a shaft member in a vertical plane of the building wall space, In the vibration of the building column, it is possible to hardly cause bending deformation in the lateral member, and thus, it is possible to effectively cause the relative displacement of both lateral members due to the vibration of the pair of building columns, As a result of the viscous shear accommodated in the box being greatly viscous sheared by the brake plate, the building columns can be effectively damped by the damping wall placed in the building wall space, and the structure can be effectively damped. be able to.

  In a preferred example of the present invention, the other horizontal end of each of the pair of transverse members may be fixedly connected to the other building column of the pair of building columns. Similarly, it may be connected to the other building column via another shaft member so as to be rotatable in the vertical plane of the building wall space, and thus the horizontal ends of each of the pair of horizontal members are connected to each other. In addition, if each shaft member is rotatably connected in the vertical plane of the building wall space, the relative displacement of both lateral members due to the vibration of the pair of building columns can be more effectively generated. As a result of preventing the decrease in the viscous shear amount due to the viscous material brake plate housed in the box, the vibration damping of the building column by the damping wall placed in the building wall space, and hence the vibration damping of the structure is further improved. Can be done effectively.

  In the present invention having a pair of cross members, one of the pair of building beams is juxtaposed adjacent to the cross member disposed above the pair of cross members and is positioned in the horizontal direction. Each end is fixedly connected to a pair of building columns, and the other of the pair of building beams is juxtaposed adjacent to the lateral member disposed below the pair of lateral members. And may be fixedly connected to a pair of building columns at each end in the horizontal direction.

  When such a pair of building beams is provided, it is possible to provide a vibration control structure having the function of the original beam, and in order to prevent the destruction of the building beam, from the end thereof. Although it may be configured to be easily bent and deformed at a slightly separated portion, in the present invention, it is not always necessary to provide such a region easily bent and deformed in a pair of building beams.

  The brake plate is fixedly connected to a portion of the horizontal member of the pair of horizontal members at the upper edge portion thereof at a distance of more than half of the interval between the pair of building columns from the other building column. The body may be fixedly connected at a lower edge of the other horizontal member of the pair of horizontal members to a site separated from the other building column by more than half of the interval between the pair of building columns, According to such a brake plate and box, a viscous brake plate accommodated in the box can be used, which can utilize the horizontal relative vibration of the pair of transverse members that reflects the vibration of the pair of building columns almost as they are. As a result, it is possible to more effectively attenuate the vibration of the building column and, moreover, the vibration of the structure by the damping wall disposed in the building wall space.

  Another vibration control structure of the present invention is defined by a pair of building columns juxtaposed to each other, a pair of building beams juxtaposed to each other by bridging the pair of building columns, and a pair of building columns and building beams. A pair of horizontal members arranged in the building wall space, and a vibration control that is arranged between the pair of horizontal members and attenuates the vibration of a pair of horizontal building columns in the vertical plane of the building wall space One of the pair of building beams is juxtaposed adjacent to the horizontal member disposed above the pair of horizontal members and each end in the horizontal direction And the other building beam of the pair of building beams is juxtaposed adjacent to the horizontal member disposed below the pair of horizontal members. Each end of the horizontal direction is fixedly connected to a pair of building columns, and each of the horizontal members of the pair of transverse members One end of the direction is connected to one of the pair of building columns, and the other horizontal end of each of the pair of horizontal members is adjacent to each of the pair of horizontal members Are connected to the horizontal center of each of the building beams juxtaposed with each other with at least one of the freely movable and linear motion within the vertical plane of the building wall space.

The damping wall is in the vertical plane of the building wall space of the brake plate against the box body caused by the horizontal vibration in the vertical plane of the building wall space of the building column through the pair of lateral members. Relative vibration causes at least viscous shear to the viscous body to attenuate horizontal vibration in the vertical plane of the building wall space of a pair of building columns.

  When each end of the building beam is fixedly connected to each of the building columns, the horizontal central portion of the building beam becomes a node of deformation and is almost displaced even in the vibration of the building column. Therefore, the other horizontal end of each of the pair of transverse members is connected to the substantially central portion of the building beam in the horizontal direction with at least one of the freely movable and linearly movable properties. The effect of bending deformation of building beams can be reduced as much as possible in the vibration of building columns, and the vibration damping of building columns by the damping wall placed in the building wall space, and hence the vibration damping of structures, can be performed even more effectively. be able to.

  In another damping structure of the present invention, one horizontal end of each of the pair of transverse members may be fixedly connected to one building column of the pair of building columns, Preferably, one of the pair of building columns is rotatably connected to a building column via a shaft member in a vertical plane of the building wall space, and the other horizontal member of each of the pair of horizontal members The end portions may be rotatably connected within the vertical plane of the building wall space to substantially horizontal central portions of the building beams adjacent to each other and juxtaposed to the pair of transverse members, Instead of or together with this, the other horizontal end of each of the pair of transverse members is substantially the center in the horizontal direction of each of the building beams arranged adjacent to each other of the pair of transverse members. It may be connected so that it can move freely in the vertical plane of the building wall space.

And it may have a damping wall for building beams.

  Since the shaft coupling mechanism 18 and the shaft coupling mechanism 20 are configured in the same manner, the shaft coupling mechanism 20 will be described below. The shaft coupling mechanism 20 is welded and riveted to the flange portion 21 of the H-shaped steel of the building column 2. , And a shaft member 24 rotatably passing through the forked portion 22 of the forked bearing 22 and the web portion 23 of the H-shaped steel of the building beam 6. The end portion 16 is connected to the building column 2 via the shaft member 24 so as to be rotatable in the R1 direction within the vertical plane of the building wall space 7.

  The damping wall 8 is more than half of the horizontal interval D between the building column 3 and the building columns 2 and 3 at the flange portion 45 of the building beam 5 via the upper mounting mechanism 32 at the upper edge portion 31 extending in the horizontal direction H. A lower mounting mechanism comprising a braking plate 33 fixedly connected to a part of the distant range d1 and suspended from the building beam 5 and arranged in the vertical plane of the building wall space 7, and a lower edge 34 extending in the horizontal direction H The flange portion 37 of the building beam 6 is fixedly connected to a portion of a range d2 that is more than half of the horizontal interval D from the building column 3 through a plurality of bolts and nuts 36 as 35, and the brake plate 33 A box body 41 that receives the brake plate 33 with a gap 40 on the inner surface 39 with respect to the outer surface 38, and a viscous body 42 such as high-viscosity silicone oil or bitumen disposed in the gap 40 are provided.

  The upper mounting mechanism 32 includes an upper gusset plate 46 fixedly connected by welding or the like at an upper edge extending in the horizontal direction H to a portion within the range d1 of the H-shaped steel flange portion 45 of the building beam 5, and the braking plate 33. A flange plate 47 fixedly connected to the upper edge portion 31 by welding or the like on the lower surface, and a lower gusset plate 48 fixedly connected to the upper surface of the flange plate 47 by welding or the like at the lower edge extending in the horizontal direction H; A pair of splice plates 50 and 51 in which the upper gusset plate 46 and the lower gusset plate 48 are connected via a plurality of bolts 49 and the upper gusset plate 46 and the lower gusset plate 48 are connected, and the upper gusset plate 46 and the lower gusset plate 48 And a plurality of reinforcing ribs 52 fixed to each of them by welding or the like.

  The box 41 that accommodates the viscous body 42 is a bottom plate as a lower edge portion 34 that is fixedly connected to a portion within the range d2 of the flange portion 37 of the H-shaped steel of the building beam 6 via a plurality of bolts and nuts 36. 56, a rectangular cylinder 57 fixed to the bottom plate 56 by welding or the like, and a plurality of reinforcing members 58 fixed to the outer surface of the side wall of the cylinder 57 by welding or the like and extending in the horizontal direction H. The inner surface 39 of the box body 41 is composed of the upper surface 59 of the bottom plate 56 and the inner peripheral surface 60 of the cylinder body 57, and the gap 40 of the box body 41 is inserted from the upper end of the opening of the cylinder body 57. The brake plate 33 is located between the entire outer surface 38 and the inner surface 39.

  The damping wall 8 is the building wall of the braking plate 33 against the box 41 generated via the building beams 5 and 6 due to the horizontal vibration in the vertical direction of the building wall space 7 of the building columns 2 and 3. The relative vibration in the horizontal direction H in the vertical plane of the space 7 causes viscous shearing to occur in the viscous body 42 to attenuate the horizontal vibration in the vertical plane of the building wall space 7 of the building columns 2 and 3. It is supposed to be.

  In the above damping structure 1, if an earthquake is applied to the damping structure 1 installed on the ground, and the building columns 2 and 3 vibrate in the same direction in the horizontal direction H in the vertical plane of the building wall space 7, The building beam 6 is relatively displaced in the horizontal direction H in the vertical plane with respect to the building beam 5, and the braking plate 33 is also relatively in the horizontal direction H in the vertical plane with respect to the box body 41 due to this vibration displacement. As a result of the vibration displacement, the viscous body 42 accommodated in the box 41 and disposed in the gap 40 is sheared by the vibration displacement brake plate 33, and as a result, a damping force based on the shear resistance force is vibrated on the brake plate 33. A damping force is applied to the braking plate 33 which is displaced, and a damping force is applied to the vibration in the horizontal direction H in the vertical plane of the building wall space 7 of the building columns 2 and 3 connected to the braking plate 33 via the building beam 5. In this case, the damping force is applied to the horizontal H vibration of the damping structure 1 and the horizontal H earthquake of the damping structure 1 is applied. Early to reduce.

  By the way, in the damping structure 1, the building beam 5 and the lower edge 34 of the box 41 in which the upper edge part 31 of the braking plate 33 is fixedly connected to the part within the range d1 Ends 15 and 16 in the horizontal direction H of the building beam 6 that are fixedly connected to each other are rotatable in the R1 direction in the vertical plane of the building wall space 7 via the shaft member 24 to the building column 2. Compared with the case where the end portions 15 and 16 are fixedly connected in the same manner as the end portions 17 and 19 because they are connected, in the vertical plane of the building wall space 7 of the building columns 2 and 3. It is possible to hardly cause bending deformation at one end side 15 and 16 of the horizontal direction of each of the building beams 5 and 6 in the vibration of the horizontal direction H, and thus the building wall space of the building columns 2 and 3 The relative displacement of both building beams 5 and 6 due to horizontal H vibration in the vertical plane of As a result, it is possible to prevent the lowering of the viscous shear amount by the brake plate 33 of the viscous body 42 accommodated in the box body 41, and as a result, the building by the damping wall 8 arranged in the building wall space 7. It is possible to effectively attenuate the vibrations of the pillars 2 and 3 and hence the vibration control structure 1.

  In other words, each of the building beams 5 and 6 is fixedly connected to the building columns 2 and 3 at both ends 15 and 16 and 17 and 19 in the horizontal direction H, so that the frame frame, in particular, both ends 15 and 16 and If the rigid frame is constructed with a plastic deformation region in which the bending rigidity is lowered and the bending is easily deformed at the part of the building beams 5 and 6 slightly separated from 17 and 19, the vertical direction of the building wall space 7 of the building columns 2 and 3 In the horizontal direction H, the building beams 5 and 6 are flexibly deformed so that each of the building beams 5 and 6 is greatly undulated, and the size of the horizontal direction H in the vertical plane of the building wall space 7 of the building columns 2 and 3 is increased. Although it is difficult to obtain a relative displacement of a corresponding size between the box body 41 and the brake plate 33, the end portions 15 and 16 are connected to the building column 2 via the shaft member 24 as described above. 7 Rotatable in the R1 direction within the vertical plane Then, the buildings at the side portions 15 and 16 that are more than half the horizontal distance D from the building column 3 in the horizontal direction H vibration in the vertical plane of the building wall space 7 of the building columns 2 and 3 The bending deformation of each of the beams 5 and 6 can be suppressed, and a relative displacement having a magnitude substantially corresponding to the magnitude of the vibration in the horizontal direction H in the vertical plane of the building wall space 7 of the building columns 2 and 3 can be obtained. The horizontal direction in the vertical plane of the building wall space 7 of the building columns 2 and 3 can be obtained between the box body 41 and the braking plate 33 and thus by the damping wall 8 arranged in the building wall space 7. It is possible to effectively attenuate the vibration of H, and hence the structure.

  In the above-described vibration control structure 1, one end portions 15 and 16 of the building beams 5 and 6 are connected to the building column 2 via the shaft member 24 so as to be rotatable in the vertical plane of the building wall space 7. Instead, as shown in FIG. 4, the building beams 5 and 6 are fixed to the building pillars 2 and 3 by welding, rivets, bolts, etc. at both ends 15 and 16 and 17 and 19 in the horizontal direction H, respectively. In the seismic control structure 70 which is connected to the frame and is rigidly connected to the frame, a pair of lateral members 71 arranged in the building wall space 7 and surrounding the building wall space 7 in cooperation with the building columns 2 and 3 and 72 and the damping wall 8 may be provided between the pair of lateral members 71 and 72 in the vertical direction V.

  And a pair of lateral members 71 and 72 which bridge the pair of building columns 2 and 3 and are juxtaposed with each other and cooperate with the pair of building columns 2 and 3 to surround the building wall space 7. Further, of the pair of lateral members 71 and 72, the side members 71 disposed adjacent to each other are juxtaposed, and the end portions 15 and 17 are welded, rivets, and bolts to the pair of building columns 2 and 3, respectively. The building beam 5 fixedly connected to each other and the horizontal member 72 disposed below the pair of horizontal members 71 and 72 are juxtaposed and disposed at the end portions 16 and 19 respectively. In the vibration control structure 70 including the building beam 6 fixedly connected to each of the pair of building columns 2 and 3 by welding, rivets, bolts or the like, the horizontal direction H of each of the horizontal members 71 and 72 is provided. One end portions 75 and 76 of the shaft coupling mechanism 1 Are connected to the building column 2 through the shaft members 79 and 80 of the shaft connecting mechanisms 77 and 78 similar to those in the vertical direction of the building wall space 7 so as to be rotatable in the R1 direction. The other end portions 85 and 86 in the horizontal direction H of the building wall 3 are respectively connected to the building column 3 via shaft members 89 and 90 of other shaft coupling mechanisms 87 and 88 similar to the shaft coupling mechanism 18. It is connected to the R2 direction in the vertical plane so as to be rotatable, and is arranged in the building wall space 7 defined by the pair of building columns 2 and 3 and the building beams 5 and 6, and in the vertical plane of the building wall space 7. The damping plate 33 of the damping wall 8 that attenuates the horizontal vibration of the pair of building pillars 2 and 3 at the upper side is fixedly connected to the lateral member 71 via the upper mounting mechanism 32 at the upper edge portion 31. It hangs down from the horizontal member 71 and is arranged in the vertical plane of the building wall space 7. , Box body 41 of the seismic damping wall 8, a plurality of bolts at the bottom plate 56 - are fixedly coupled to the upper surface of the horizontal member 72 through the nut 36.

  Also in the vibration control structure 70, if an earthquake is applied to the vibration control structure 70 installed on the ground, and the building columns 2 and 3 vibrate in the same direction in the horizontal direction H in the vertical plane of the building wall space 7, The building beam 6 and the transverse member 72 are oscillated and displaced relative to the beam 5 and the transverse member 71 in the horizontal direction H, and the braking plate 33 is also moved in the vertical plane of the building wall space 7 with respect to the box body 41 by this oscillating displacement. As a result, the viscous body 42 accommodated in the box 41 and disposed in the gap 40 is sheared by the braking plate 33 that is displaced in the horizontal direction H. As a result, the braking plate 33 is sheared. A damping force based on the resistance force is applied to the braking plate 33 that is subjected to vibration displacement, and the horizontal direction H in the vertical plane of the building wall space 7 of the building columns 2 and 3 connected to the braking plate 33 via the lateral member 71 is obtained. Attenuating force is applied to the vibration, and it is reduced to the horizontal vibration of the damping structure 70. Empower, early reduce the vibration in the horizontal direction H of the vibration control structure 70.

  In the case of the vibration control structure 70, a horizontal member 71 to which the upper edge 31 of the brake plate 33 is fixedly connected and a horizontal member 72 to which the lower edge 34 of the box 41 is fixedly connected. End portions 75 and 76 in the horizontal direction H of both lateral members 71 and 72 are connected to the building column 2 via shaft members 79 and 80 so as to be rotatable in the R2 direction in the vertical plane of the building wall space 7. In addition, both lateral members 71 and 72 are a lateral member 71 to which the upper edge portion 31 of the brake plate 33 is fixedly connected and a lateral member 72 to which the lower edge portion 34 of the box 41 is fixedly connected. Since the end portions 85 and 86 in the horizontal direction H are connected to the building column 3 via shaft members 89 and 90 so as to be rotatable in the R1 direction in the vertical plane of the building wall space 7, 5 is welded, riveted, bolted, etc. to the pair of building pillars 2 and 3 at its ends 15 and 17 Even if the building beam 6 is more fixedly connected and the building beam 6 is fixedly connected to each of the pair of building columns 2 and 3 by welding, rivets, bolts, etc. at the ends 16 and 19, respectively, The bending deformation of the transverse members 71 and 72 due to the vibration in the horizontal direction H within the vertical plane of the building wall space 7 of the columns 2 and 3 can be reduced, and thus the vertical plane of the building wall space 7 of the building columns 2 and 3 The relative displacement in the horizontal direction H in the vertical planes of the lateral members 71 and 72 due to the horizontal vibration in the horizontal direction can be more effectively generated and accommodated in the box body 41. As a result of the viscous body 42 being able to be largely sheared viscously by the brake plate 33, the vibration damping of the building columns 2 and 3 by the damping wall 8 arranged in the building wall space 7, and hence the damping of the damping structure 1 are reduced. It can be done more effectively.

  In the case of the vibration control structure 70, both end portions 75 and 76 and 85 and 86 of the transverse members 71 and 72 are rotatable with respect to the building columns 2 and 3, but the respective ends of the transverse members 71 and 72 are provided. While the portions 75 and 76 are rotatable in the R1 direction with respect to the building column 2, the end portions 85 and 86 of the transverse members 71 and 72 may be fixed to the building column 3 and vice versa. Moreover, the end portions 75 and 86 of the transverse members 71 and 72 are rotatable in the R1 direction and the R2 direction with respect to the building columns 2 and 3, respectively, while the respective ends of the transverse members 71 and 72 are provided. The portions 76 and 85 may be fixed with respect to the building columns 2 and 3, or vice versa.

  In the vibration control structure 70, the respective end portions 75 and 76 of the lateral members 71 and 72 are rotatable in the R1 direction with respect to the building column 2, while the respective end portions 85 and 86 of the lateral members 71 and 72 are made to rotate. When fixed to the building column 3, as in the case of the vibration control structure 1, the building column 2 in which the upper edge 31 of the braking plate 33 is separated from the building column 3 by more than half of the horizontal distance D in the horizontal member 71. The lower edge 34 of the box 41 may be fixedly connected to the site on the side of the building column 2 that is more than half of the horizontal distance D from the building column 3 in the horizontal member 72. The respective end portions 85 and 86 of the lateral members 71 and 72 are rotatable in the R2 direction with respect to the building column 3 while the respective end portions 75 and 76 of the lateral members 71 and 72 are made to be movable with respect to the building column 2. In the case of fixing, the brake plate 33 is contrary to these. The upper edge 31 is fixedly connected to a part on the side of the building column 3 that is separated from the building column 2 by more than half of the horizontal distance D in the horizontal member 71, and the lower edge 34 of the box 41 is similarly connected to the building in the horizontal member 72. It may be fixedly connected to a part on the side of the building column 3 that is separated from the column 2 by more than half of the horizontal interval D.

  In the vibration control structure 70, both end portions 75 and 76 and 85 and 86 of the transverse members 71 and 72 are rotatable in the R1 and R2 directions with respect to the building columns 2 and 3, but instead of this, FIG. As shown in FIG. 5, both end portions 75 and 76 of the horizontal members 71 and 72 are connected to the building column 2 so as to be rotatable in the R2 direction, while both end portions 85 of the respective horizontal members 71 and 72 are connected. And 86 are connected to the substantially central portions in the horizontal direction H of the building beams 5 and 6 via the sliding support mechanisms 95 and 96 so as to be movable in the horizontal direction H in the vertical plane of the building wall space 7, Similarly to the above, the damping wall 8 may be provided between the pair of lateral members 71 and 72 in the vertical direction V.

  Since the sliding support mechanism 95 and the sliding support mechanism 96 are configured similarly, the sliding support mechanism 95 will be described. The sliding support mechanism 95 includes a rod 97 fixed to the end portion 85 of the lateral member 71, a rod 97 includes a sliding bearing member 98 that is slidably movable in the horizontal direction H and fixedly connected to the building beam 5 by welding or the like, and has an end portion 85 of the transverse member 71 with respect to the building beam 5. The relative linear movement in the horizontal direction H within the vertical plane of the building wall space 7 is allowed.

  The horizontal direction H ends 85 and 86 of the pair of transverse members 71 and 72 are adjacent to each of the pair of transverse members 71 and 72, and the horizontal beams H of the building beams 5 and 6 are juxtaposed. The seismic control structure 99 shown in FIG. 5 which is movable at a substantially central portion, that is, is connected to the building column 3 by being directly movable in the horizontal direction H in the vertical plane of the building wall space 7 is also used for the building beam 5. Are fixedly connected to the pair of building pillars 2 and 3 at their ends 15 and 17 by welding, rivets, bolts, and the like, and the building beam 6 is a pair of buildings at 16 and 19 at the ends. Even if the columns 2 and 3 are fixedly connected to each of the columns 2 and 3 by welding, rivets, bolts, etc., the transverse members in the horizontal direction H in the vertical direction of the building wall space 7 of the building columns 2 and 3 The bending deformation of 71 and 72 can be reduced, and thus the building column 2 and The horizontal displacement H of the lateral members 71 and 72 in the vertical plane of the building wall space 7 due to the horizontal vibration in the vertical plane of the building wall space 7 is more effectively generated. As a result, it is possible to prevent a decrease in the viscous shear amount by the brake plate 33 of the viscous body 42 accommodated in the box body 41. As a result, the building columns 2 and 3 by the damping wall 8 disposed in the building wall space 7 are used. The vibration damping of the seismic control structure 1 can be performed more effectively.

  In the seismic control structure 99, in particular, the horizontal direction of the building beams 5 and 6 that become nodes in the deformation of the building beams 5 and 6 in the horizontal vibration H in the vertical plane of the building wall space 7 of the building columns 2 and 3 The horizontal end portions 85 and 86 of the pair of transverse members 71 and 72 are connected to the building beams 5 and 6 in the vertical plane of the building wall space 7 through the sliding bearing member 98 fixed to the substantially central portion of H. The horizontal members 71 and 72 can be further reduced in bending deformation due to vibration in the horizontal direction H in the vertical plane of the building wall space 7 of the building columns 2 and 3. Thus, the relative displacement in the horizontal direction H in the vertical planes of the lateral members 71 and 72 due to the horizontal vibration in the vertical plane of the building wall space 7 of the building columns 2 and 3 is determined. The viscous body 42 contained in the box 41 can be generated more effectively. As a result of preventing the decrease in the viscous shear amount due to the moving plate, the vibration damping of the building columns 2 and 3 by the damping wall 8 arranged in the building wall space 7 and further the damping of the damping structure 1 are further increased. Can be done effectively.

  In the vibration control structure 99, the end portions 85 and 86 in the horizontal direction H of the pair of transverse members 71 and 72 are arranged at the substantially central portions in the horizontal direction H of the building beams 5 and 6, respectively. However, instead of this, it may be connected so as to be rotatable, or it may be connected using, for example, a universal joint, preferably a spherical bearing. In short, what is necessary is just to be connected with at least one of the flexibility and the freely movable.
