Conventional high-rise buildings have not adopted vibration damping devices that are effective against wind or small to medium earthquakes. For this reason, the vibration damping constant of high-rise buildings is generally very small, and vibrations sometimes become a problem during strong winds such as typhoons. Therefore, some proposals are being made to prevent vibrations in high-rise buildings by incorporating viscous dampers or friction dampers into the walls of buildings.

However, when incorporating a viscous damper into the inner wall, there are restrictions on layout planning, such as how to deal with conventional seismic walls, and with friction dampers, there are problems such as the inability to expect a damping effect at minute amplitudes. This invention was devised to solve the above-mentioned conventional problems, and its purpose is to eliminate the need to consider dealing with earthquake walls, and to work reliably even in the case of minute amplitudes, so that strong winds Another object of the present invention is to provide a seismic wall having a vibration damping function with a new configuration that can reduce the amplitude of a building during a small to medium earthquake.

The features of this invention for the above-mentioned purpose are: an unbonded steel plate installed along the sides of a seismic wall slab; an in-plate gusset plate inscribed on the upper and lower sides of the center of the plate; In a seismic wall having a brace material provided across the set plate, and in which the upper and lower ends of the in-plate gusset plate and the unbonded steel plate are joined to the beam side gusset plate with bolts and fixed to the upper and lower girders, the unbonded steel plate is fixed to the upper and lower girders. In addition to attaching auxiliary steel plates to both sides of the wall, a vibration-damping viscoelastic material layer is installed between the auxiliary steel plate and the unbonded steel plate and wall slab concrete, and the auxiliary steel plate is attached to the upper and lower girders through the beam side gusset plate. It is to join to.

In the above earthquake-resistant wall, when a horizontal force acts on the joint between the auxiliary steel plate and the upper and lower girders, the earthquake-resistant wall plate begins to rotate around the gusset plate at the center of the plate as a fulcrum.
Misalignment occurs between the auxiliary steel plates connected to the upper and lower girders and the unbonded steel plates and wall slab concrete. However, since a viscoelastic material layer is interposed between these parts, resistance is generated depending on the relative movement speed of each part, and the vibration is controlled by this resistance.

In the figure, reference numeral 1 is an earthquake-resistant wall slab, and steel plates (hereinafter referred to as unbonded steel plates) 2, 2 whose surfaces have been treated to eliminate concrete adhesion are installed along both sides. Gusset plates 3, 3 are provided at the center of the unbonded steel plates 2, 2, and the brace material extends between the gusset plates 3, 3 and the in-plate gusset plates 4, 4 arranged at the center of the upper and lower sides of the center of the plate. 5,5 are arranged. Auxiliary steel plates 6, 6 are attached to both sides of the unbonded steel plates 2, 2. This auxiliary steel plate 6,6
and the above unbonded steel plate 2 and wall slab concrete 9
Viscoelastic material layers 10, 10 including the gusset plate 3 are provided between them. Note that the upper and lower ends of the illustrated auxiliary steel plate 6 are formed with joint plates 6a connected by welding. A seismic wall with such a structure is constructed by joining the upper and lower ends of the inner gusset plates 4, 4 and the unbonded steel plates 2, 2 to the beam side gusset plates 8, 8 with bolts 11, 11, and then attaching the upper and lower girders 7, 7, and when the unbonded steel plates 2, 2 are joined, the upper and lower ends of the auxiliary steel plates 6, 6 are also joined to the upper and lower girders 7, 7 via the beam side gusset plates 8. In the seismic wall constructed as described above, when a horizontal force such as an earthquake force acts on the upper and lower girders 7, the seismic wall slab 1 rotates about the inner gusset plate 4 at the center of the slab as a fulcrum. At this time, a vertical reaction force is generated in the unbonded steel plate 2 due to the rotational moment, but since the central part is joined to the brace material 5, the upper part of the unbonded steel plate 2 is stretched by the action of tensile force across the joined part.
On the other hand, compressive force is generated in the lower part, causing it to contract and expand and deform in the form of a spring. As a result, in addition to the shear deformation and bending deformation of the shear wall plate 1 itself, the rotational deformation due to the expansion and contraction of the unbonded steel plate 2 is added to the seismic wall plate 1, and the excessive rigidity peculiar to shake-resistant walls is adjusted to an appropriate rigidity, and the expansion and contraction This occurs between the auxiliary steel plate 6 and the auxiliary steel plate 6 that does not cause this. This misalignment also occurs between the wall slab concrete 9, and the misalignment between the unbonded steel plate 2 and the seismic wall slab 1 is large at the center, and hardly occurs at the edges.
Since the auxiliary steel plate 6 is not connected at the center with a gusset or the like, misalignment with the wall slab occurs over the entire surface from top to bottom, thereby ensuring a large amount of misalignment, increasing viscous resistance, and increasing the vibration damping function. . Corresponding to this action, the viscoelastic material layers 10, 10 on both sides of the auxiliary steel plate 6 act as resistance against displacement. This resistance occurs depending on the relative movement speed between each part, and the upper and lower girders 7, 7 The horizontal force applied to the wall is attenuated within the seismic wall slab, reducing vibration. The illustrated earthquake-resistant wall version 1 has damping means in both side edges, but the earthquake-resistant wall of the present invention has vibration-resistant wall version 1 described above.
It may have a structure in which it is divided into two parts from the central part.

As described above, this invention provides a viscoelastic material layer between an unbonded steel plate installed along the side of a seismic wall slab and an auxiliary steel plate, and between an auxiliary steel plate and wall slab concrete, thereby forming an unbonded steel plate. The auxiliary steel plate provides earthquake resistance to the wall slab, and the viscoelastic material layer can attenuate vibrations. There are no restrictions on the layout plan, such as the arrangement of Furthermore, since it acts on minute amplitudes that cannot be expected with friction dampers, it is possible to control building vibrations not only during earthquakes but also during strong winds. Furthermore, since it is only necessary to apply vibration damping means to the sides of the earthquake-resistant wall slab, its function as an earthquake-resistant wall is not impaired, and it has the advantage that it can be attached to the upper and lower girders as before.
