Stay cable type steel plate shear wall

Abstract

The invention discloses a stay cable type steel plate shear wall. The stay cable type steel plate shear wall comprises an embedded steel plate and a concrete frame, wherein the embedded steel plate is a thin steel plate, two steel support pillars are respectively welded at two ends of the embedded steel plate, the upper end and the lower end of each steel support pillar are fixed on an upper frame beam and a lower frame beam of the concrete frame through high strength bolts, an upper through hole and a lower through hole are formed in the middle of each steel support pillar, a pre-stressing cable passes through all the through holes in the steel support pillars, and two ends of the pre-stressing cable are respectively fixed on the upper frame beam and the lower frame beam through connection ear plates. The stay cable type steel plate shear wall is high in support intensity, good in shock resistance and high in ductility, obtains a full energy consumption hysteretic loop, and is a superior multipurpose lateral force resistance energy consumption member.

Description

technical field [0001] The invention relates to the technical field of shear walls, in particular to a cable-stayed steel plate shear wall. 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 steel plate, the steel plate shear wall...

AI Technical Summary

Problems solved by technology

In this process, the steel plate cannot bear the load, and the structure only relies on the beams and columns to bear the external load. Since the support strength of the beams and columns is low, the tension field anchored on the frame will generate a large additional bending moment on the side columns, increasing the Stability burden of the column

As the vertical load-bearing components of the building, the columns need to have a high supporting strength. If they are damaged, the entire structure may collapse, causing unsafe factors.

In addition, a defect of the traditional steel plate shear wall is that it is impossible to open holes in the steel plate wall. In this way, the steel plate wall cannot be used as a lateral force-resisting member in the place where the opening needs to be opened in the building, thus greatly reducing the Application range of steel plate wall as a new type of component
