Prestressed steel plate shear wall capable of separating tension field

Abstract

The invention provides a prestressed steel plate shear wall capable of separating a tension field, and relates to the field of civil engineering. The prestressed steel plate shear wall capable of separating the tension field is a novel energy-consuming and buckling-restrained shear wall component. The technical problems that a diagonal tension field is formed after the traditional steel plate shear wall is stressed, steel plates are buckled, and components are damaged are solved. The prestressed steel plate shear wall capable of separating the tension field mainly comprises a steel plate wall, a prestressed cable, a perforated diagonal bracing, a perforated rib plate, a corner connector and a horizontal edge connector. The prestressed cable is separated from the steel plate wall, so that the prestressed cable bears all diagonal tension, the problem that the traditional steel plate wall is damaged due to the tension field is solved, after the cable is tensioned, buckling of the steel plate wall out of a plane can be limited, and the steel plate wall is protected well, and only needs to bear diagonal pressure and horizontal shear. By the method for separating the diagonal tension of the steel plate wall through the prestressed cable, the steel plate wall has features of good anti-seismic property and high ductility, and is a high-performance lateral force resistant component for a high-rise building structure or other structures.

Description

Technical field [0001] The invention relates to the field of civil engineering, and is a new type of shear wall component that consumes energy and prevents steel plate buckling. Background technique [0002] The steel plate shear wall is usually composed of an edge frame and an embedded steel plate. The edge frame bears the overturning moment caused by the lateral load, and the embedded steel plate bears the lateral load. Compared with reinforced concrete shear walls, steel plate shear walls have higher initial stiffness, good ductility and energy dissipation capacity. The steel plate shear wall is thin, which can effectively reduce the weight of the structure, lower the cost of the foundation, and is easy to replace after an earthquake. [0003] When the steel plate shear wall is relatively thick, it buckles in the elastic stage and forms a series of parallel diagonal tension belts to resist the horizontal load. The shear wall changes from elastic buckling to the initial yieldin...
