Buckling constraint steel plate shear wall capable of being used as vertical bearing component

Abstract

The invention relates to the technical field of structural engineering, and particularly relates to a buckling constraint steel plate shear wall capable of being used as a vertical bearing component. The buckling constraint steel plate shear wall capable of being used as the vertical bearing component comprises an embedded steel plate, a concrete cover board, an edge component, a longitudinal stiffener, a longitudinal steel plate strip and a transverse steel plate group, wherein the concrete cover board, the longitudinal steel plate strip and the transverse steel plate group are fixedly connected with the embedded steel plate, so that an out-of-plane constraint is added to the embedded steel plate in both the horizontal direction and the vertical direction; in addition, the large embedded steel plate is divided into small cells by the longitudinal steel plate strip and the transverse steel plate group, so that the carrying capacity of the steel plate shear wall can be improved and out-of-plane buckling of the embedded steel plate is effectively prevented. Therefore, the energy-dissipating capacity, the lateral rigidity and the ductility performance of the steel plate shear wall are greatly improved, and the buckling constraint steel plate shear wall can be used as the bearing component in the structure to share the burden of the other bearing components in the structure.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a steel plate shear wall which has relatively large lateral rigidity, relatively high late bearing capacity, and relatively strong energy dissipation capacity, and can be used as a vertical load-bearing component in a structure. Background technique [0002] Steel plate shear wall is a new type of lateral force resistance structure developed in the 1970s. It has good ductility and ductility, large lateral stiffness, strong energy dissipation capacity, and outstanding seismic performance. Developed countries such as the United States and Japan have taken the lead in applying it to practical projects. In recent years, some high-intensity areas in my country have gradually begun to apply it, such as: Tianjin Tower in Tianjin, Shanghai Jinjiang Hotel, etc. In the early design of steel plate shear walls, the elastic buckling load was used as the limit state of the beari...

AI Technical Summary

Problems solved by technology

However, since the buckling of the embedded steel plate is constrained by the concrete cover slab from the very beginning, the concrete cover slab is always in a bending state, causing an excessive burden on the concrete cover slab, and the concrete cover slab may occur prematurely. damage, the restraining effect on the embedded steel plate is weakened

In addition, because the embedded steel plates used in traditional buckling-resistant steel plate shear walls are relatively thin, generally only the influence of shear force on its performance is considered when the force is applied, and vertical loads are avoided as much as possible to avoid excessive damage to the steel plate shear walls. Early failure, so it cannot share the burden of load-bearing components in the structure, and its contribution to the entire structural system is limited
