  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, the braking plate is almost entirely formed including the region where the upper building beam is easily deformed, and the lower building beam adjacent to the upper building beam is also easily deformed. Boxes that receive the brake plate with a gap are attached to almost the entire area including the area where the brake plate is attached, and the brake plate is displaced by the relative displacement of the lower building beam with respect to the upper building beam due to the vibration of the pair of building columns. When a relative displacement is generated in the box body and the viscous body accommodated in the box body is caused to cause viscous shear to attenuate the vibration of a pair of building columns as described above, When the brake plate and the box are attached to each other including the region that is easily bent and deformed slightly away from the end, the region where each building beam is easily bent and deformed is constrained. The relative displacement of the box is reduced, building pillars Vibration damping, and by extension there is a risk that not obtained effectively perform vibration damping of 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 damping wall that is arranged in the building wall space and attenuates the vibration of a pair of building pillars in the horizontal direction in the vertical plane of the building wall space, and the damping wall extends in the horizontal direction. A brake plate fixedly connected to the upper building beam of the pair of building beams at the edge and suspended from the upper building beam side, and arranged in the vertical plane of the building wall space, and a pair of building columns The lower edge of the pair of building beams is fixedly connected to the lower building beam at the lower edge extending in the horizontal direction only in the range between each of the areas excluding each of the areas where the bending deformation of the lower building beam is easy. Upright from the building beam side of the building and against the outer surface of the brake plate And the damping wall is generated by a pair of building beams due to horizontal vibration in the vertical plane of the building wall space of the building column. The relative vibration in the vertical plane of the building wall space of the brake plate against the wall causes at least viscous shear in the viscous body to attenuate horizontal vibration in the vertical plane of the building wall space of a pair of building columns It has become.

  According to the present vibration control structure, the box is fixedly connected to the lower building beam of the pair of building beams at the lower edge extending in the horizontal direction only in the above range. The fixed connection to the lower building beam effectively prevents relative deformation in the horizontal direction of both building beams caused by the vibration of a pair of building columns without obstructing the ease of bending deformation of the lower building beam. As a result, it is possible to prevent a decrease in the viscous shear amount due to the brake plate of the viscous material housed in the box, resulting in the vibration attenuation of the building column due to the damping wall placed in the building wall space, and eventually It is possible to effectively attenuate the vibration of the damping structure.

  In one example of the invention, each of the regions has at least the length of the beam of the lower building beam.

  In the present invention, in a preferred example, the brake plates are also paired at the upper edge extending in the horizontal direction only in the range between the pair of building columns and the regions where bending deformation of the upper building beam is easy. In this example, each of the regions where the bending of the upper building beam is easily deformed from each of the pair of building pillars is at least upper. It may have the length of the beam of the building beam.

  According to another aspect of the present invention, there is provided a vibration control structure comprising a pair of building columns juxtaposed to each other, a pair of building beams bridging the pair of building columns and juxtaposed to each other, and a pair of building columns and building beams.

The damping wall is provided with a damping plate for the box that is generated via a pair of building beams due to horizontal vibration in the vertical plane of the building wall space of the building column. Relative vibrations in the vertical plane of the building wall space cause at least viscous shear in the viscous body to attenuate horizontal vibrations in the vertical plane of the building wall space of a pair of building columns. .

  Even in such a vibration control structure, the box body is fixedly connected to the lower building beam of the pair of building beams at the lower edge portion extending in the horizontal direction only in the above range. The fixed connection to the building beam effectively prevents relative bending in the horizontal direction of both building beams due to the vibration of a pair of building columns without impeding the ease of bending deformation of the lower building beam. As a result, it is possible to prevent a decrease in the viscous shear amount due to the brake plate of the viscous material housed in the box, and as a result, the vibration damping of the building column due to the damping wall arranged in the building wall space is suppressed. It is possible to effectively attenuate the seismic structure.

Fixed to the upper building beam of the pair of building beams at the lower edge that extends in the horizontal direction only within a range of ¼ or more of the horizontal interval between the pair of building columns from each of the pair of building columns. It may be connected.

  In any of the present inventions, the connection length to the upper building beam at the upper edge of the brake plate and the connection length to the lower building beam at the lower edge of the box are substantially equal in the preferred example. However, the present invention is not limited to this, and may be different from each other. In the entire range, the brake plate is fixedly connected to the upper building beam at the upper edge thereof, and the box body. May be fixedly connected to the lower building beam at its lower edge, but in part of the range, the brake plate is fixedly connected to the upper building beam at its upper edge and the box is It may be fixedly connected to the lower building beam at the lower edge, and in addition, in a preferred example, at the same horizontal position within the range, the brake plate is connected to the upper building beam at its upper edge. The box is fixedly connected to the lower building beam at the lower edge of the box. The brake plate is fixedly connected to the upper building beam at its upper edge and the box is fixed to the lower building beam at its lower edge at different horizontal positions within the range. It may be connected to.

  In such a vibration control structure, in a preferred example, the braking plate is fixedly connected to the upper building beam at its upper edge extending in the horizontal direction only in the above range, and the box is only in the same range. It is fixedly connected to the lower building beam at its lower edge extending in the horizontal direction, but instead the braking plate is not limited to said area but includes at least one of the areas above it. The box may be fixedly connected to the building beam, and the box may be fixedly connected to the lower building beam at the lower edge extending in the horizontal direction only in the range.

  In the vibration control structure of the present invention, the brake plate itself may be fixedly connected directly to the upper building beam at the upper edge thereof, but instead, via the upper connecting means. It may be fixedly connected to the upper building beam at its upper edge, and similarly the box itself may be fixedly connected directly to the lower building beam at its lower edge. Instead of this, it may be fixedly connected to the lower building beam at the lower edge thereof via the lower connecting means.

The inner surface of the box body facing the outer surface of the brake plate with a gap has a horizontal length longer than the horizontal distance of the above range. And a pair of inner side surfaces that extend in the same direction as the lower edge portion extends and face each of the pair of outer side surfaces of the brake plate.

  According to the vibration control structure of such an example, the amount of viscous shear caused by the brake plate of the viscous material accommodated in the box is determined in the relative displacement in the horizontal direction of both building beams caused by the vibration of the pair of building columns. As a result of increasing the size, it is possible to more effectively attenuate the vibration of the building column by the damping wall arranged in the building wall space, and hence the damping of the damping structure.

  Such a damping wall 8 is a braking plate for the box 41 generated via the pair of building beams 5 and 6 due to the horizontal vibration in the vertical plane of the building wall space 7 of the building columns 2 and 3. The viscous body 42 is caused to generate at least viscous shear by the relative vibration in the vertical plane of the 34 building wall space 7, and the horizontal direction H in the vertical plane of the building wall space 7 of the pair of building columns 2 and 3 is generated. The vibration is attenuated.

  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 34 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 34, and as a result, the damping force based on the shear resistance force is vibrationally displaced. A damping force is applied to the braking plate 34, and a damping force is applied to the horizontal vibration H in the vertical plane of the building wall space 7 of the building columns 2 and 3 connected to the braking plate 34 via the building beam 5, Applying damping force to the horizontal H vibration of the damping structure 1 to accelerate the horizontal H vibration of the damping structure 1 Reduced to.

  By the way, in the damping structure 1, the brake plate 34 is fixedly connected to the building beam 5 at the upper edge 31 extending in the horizontal direction H only in the range S1, and the box 41 is also in the horizontal direction only in the range S1. Since the lower edge 35 extending to H is fixedly connected to the building beam 6, the fixed connection does not hinder the ease of bending deformation of the building beams 5 and 6 in the region S0. A relative displacement in the horizontal direction H on one building column 2 side of both building beams 5 and 6 due to the vibration of the pair of building columns 5 and 6 can be effectively generated, As a result of preventing a decrease in the viscous shear amount due to the braking plate 34 of the accommodated viscous body 42, the vibration damping of the building columns 2 and 3 by the damping wall 8 arranged in the building wall space 7, and consequently the damping structure. The vibration of the object 1 can be effectively attenuated.

  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 17 and 18 and 20 in the horizontal direction H to form a rigid frame, in particular, both ends 15 and 17. When the rigid frame is constructed with the plastic deformation region S0 that is easily bent and deformed by lowering the bending rigidity at the portions of the building beams 5 and 6 that are slightly separated from 18 and 20, the building wall space 7 of the building columns 2 and 3 In the horizontal direction H vibration in the vertical plane, each of the building beams 5 and 6 is bent and deformed in the same direction in a substantially sinusoidal manner with a node in the vicinity of a half of the horizontal interval L. The upper edge 31 extending in the horizontal direction H only in the range S1 excluding the region S0 is fixedly connected to the building beam 5 and the box 41 also extends in the horizontal direction H only in the range S1 excluding the region S0. In part 35 If the building beam 6 is fixedly connected to the building beam 6, one of the building beams 5 and 6 caused by the vibration of the pair of building columns 5 and 6 does not hinder the bending deformation of the building beams 5 and 6. As a result, it is possible to effectively cause a relative displacement in the horizontal direction H on the column 2 side and to prevent a decrease in the viscous shear amount by the braking plate 34 of the viscous body 42 accommodated in the box 41. Further, the vibration damping of the building columns 2 and 3 by the damping wall 8 arranged in the building wall space 7 and the damping of the damping structure 1 can be effectively performed.

  In the above damping structure 1, the braking plate 34 is fixedly connected to the building beam 5 at the upper edge 31 extending in the horizontal direction H only in the range S1, and the box 41 is also in the horizontal direction H only in the range S1. The extending lower edge 35 is fixedly connected to the building beam 6 via the upper connecting means 32. Instead of this, as shown in FIG. 3, the box 41 is horizontal only in the range S1 as described above. While the lower edge 35 extending in the direction H is fixedly connected to the building beam 6, the braking plate 34 is only in the horizontal direction in the range S2 from the position P1 to the position P3 located on the one building pillar 2 side from the position P1. The upper edge 31 extending to H may be fixedly connected to the building beam 5 via the upper connecting means 101.

  In this case, like the upper connecting means 32, the upper connecting means 101 is fixed to the lower surface 61 of the range S2 of the lower flange portion 33 of the H-shaped steel of the building beam 5 by welding or the like at the upper edge 62 extending in the horizontal direction H. The upper gusset plate 63, the flange plate 65 fixed by welding or the like to the entire horizontal direction H of the upper edge portion 31 of the brake plate 34, and the entire upper surface of the flange plate 65 are in contact with the entire lower surface. The upper surface 68 is entirely welded to the lower edge 67 which is overlapped with the flange plate 65 and fixed to the flange plate 65 via a plurality of bolts and nuts 66 and extends in the horizontal direction H of the upper gusset plate 63. From the fixed flange plate 69 to the upper edge 70 extending obliquely downward with respect to the horizontal direction H from the upper edge 62 extending in the horizontal direction H of the upper gusset plate 63 A flange plate 71 which is secured by contact or the like, and a plurality of reinforcing ribs 72 which are fixed by welding or the like on both surfaces of the upper gusset plate 63.

  Even in the vibration control structure 1 in which the braking plate 34 is fixedly connected to the building beam 5 via the upper connecting means 101 only in the range S2, the bending deformation of the building beam 5 is not so hindered. As a result, it is possible to prevent a decrease in the viscous shear amount due to the brake plate 34 of the viscous body 42 accommodated in the building. As a result, the vibration damping of the building columns 2 and 3 due to the damping wall 8 arranged in the building wall space 7 is suppressed. The vibration damping of the structure 1 can be effectively performed.

  Furthermore, in the above description, the upper gusset plate 63 and the lower gusset plate 83 are formed with the inclined upper edge 70 and lower edge 89 that are not fixed to the lower flange portion 33 and the upper flange portion 37, respectively. As shown, the upper gusset plate 63 and the lower gusset plate 83 may be formed with an upper edge 70 and a lower edge 89 extending in the horizontal direction H that are not fixed to the lower flange portion 33 and the upper flange portion 37, respectively.
