Prestress waveform section steel plate shear wall

Abstract

The invention relates to a prestress waveform section steel plate shear wall and belongs to the technical field of structural engineering. The prestress waveform section steel plate shear wall comprises an embedded waveform steel plate, prestress rods, connecting lug plates, brackets, edge components, frame beams and frame columns, wherein the embedded waveform steel plate is in bolt connection with the edge components, the prestress rods and the connecting lug plates are symmetrically disposed on two sides of the embedded waveform steel plate, the vertical edge components are welded with the horizontal edge components, the connecting lug plates are symmetrically arranged at beam flange parts of the beam frames and welded with the frame beams, the horizontal edge components are welded with or in bolt connection with the frame beams, the brackets are welded with the vertical edge components and the embedded waveform steel plate, and the frame beams are welded with, in bolt connection, or in welded and bolt hybrid connection with the frame columns. The prestress waveform section steel plate shear wall has the advantages of good anti-seismic performance, high ductility, saturated energy dissipation hysteretic loop, and the like, and is an excellent anti-seismic energy dissipation component.

Description

technical field [0001] The invention relates to a novel prestressed corrugated section steel plate shear wall, which belongs to the technical field of structural engineering. Background technique [0002] At present, there are more than 20 buildings in the world that use steel plate shear walls as the main anti-lateral force components, and they are mainly distributed in areas with high seismic intensity such as North America and Japan. Since Japan Steel Corporation applied steel plate shear walls to buildings in 1970, the steel plate shear walls have been developed for more than 40 years. The steel plate shear wall structural system consists of embedded steel plates and edge members, and the edge members include edge beams and edge columns. Embedded steel plates are usually connected with edge members to form a lateral force resistant structural system, which can be regarded as a cantilever beam fixed on the ground. [0003] According to the thickness of the embedded stee...

Problems solved by technology

[0005] The present invention proposes a new type of prestressed steel plate shear wall with corrugated section. Its purpose is to overcome the shortcomings of thin steel plate shear walls that cannot fully exert the strength and ductility of steel due to premature buckling, and improve the performance of steel plate shear walls. Out-of-plane stability and ultimate bearing capacity, giving full play to the advantages of steel
