Vertical shear tilt vibration damper steel plate shearing wall

Abstract

The invention belongs to the technical field of structural engineering technique, more particularly relates to a vertical shearing-resistance stepping shock-absorption armor plate shear wall that consists of an end plate, a rubber pad, an armor strut, an armor plate shear wall and a cast iron block, wherein, the two sides of the armor plate shear wall are respectively provided with the armor struts, the strut foot of the first armor strut is fixed above a base by the end plate, the first armor strut is divided into two sections at the position near the strut top, at the division position, thetop and the bottom of the upper and the lower sections of the struts are respectively provided with the end plates, the end plates are provided with round holes in which the dumb bell cast iron blockis embedded, so as to connect the upper and the lower sections of the struts into a whole, thereby forming the first armor strut. The second armor strut is divided into two sections at the position near the strut foot, at the division position, the top and the bottom of the upper and the lower sections of the struts are respectively provided with the end plates, the end plates are provided with around hole in which the dumb bell cast iron block is embedded, so as to connect the upper and the lower sections of the struts into a whole, thereby forming the second armor strut. The strut foot of the second armor strut is fixed on the base by using a base embedded piece through the end plates. The invention has the advantages of no residual deformation and small shock effect and so on, and hasexcellent shock resistance performance and ductility and hysteresis energy consumption capability.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a novel rocking vibration damping component, and further refers to a vertical shear rocking vibration damping steel plate shear wall, which is suitable for multi-high-rise building structures. Background technique [0002] Rocking shock absorption is a very novel shock absorption design concept. In the traditional seismic design concept, the upper structure is fastened to the lower foundation, the structure cannot be separated from the foundation, and the seismic force mainly depends on the lateral force-resistant members (supports, shear walls, etc.) to resist. The traditional seismic isolation technology reduces the energy input of the earthquake to the upper floors by setting a seismic isolation device with a small lateral stiffness but a large deformation capacity in a certain floor of the building, thereby reducing the seismic response of the upper...

Problems solved by technology

[0004] At present, Japan's Zhuzhong Gongwudian has applied the rocking shock absorption technology to the building structure, and adopted the "bolt type" rocking shock absorbing support, but this kind of support does not adopt energy consumption measures, so it needs to be further improved

A bridge in New Zealand also uses a lift-type rocking damping bearing placed at the bottom of the pier for shock absorption, but there is still a long way to go for the application of this rocking damping bearing in building structures

American scholars use buckling-constrained supports to improve bridge piers, allowing bridge pier to move, but the energy dissipation capacity of buckling-constrained supports is not as superior as that of steel plate shear walls, so it needs to be improved
