Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the opening of the traditional buckling-resistant steel plate shear wall needs to be equipped with opening edge members, which additionally increases the opening size of the steel plate, resulting in the weakening of the structure’s seismic performance and lower bearing capacity, and the protruding edge of the opening. Wall problems, buckling-resistant shear walls with openings and construction methods with buckling-restrained fishplates

Abstract

The invention discloses a holed buckling-restrained shear wall with buckling-restrained fishplates and a construction method, relates to shear walls and a construction method, and belongs to the field of building structures. The problems that the structural anti-seismic property is weakened, the bearing capacity is reduced and hole edge parts are prone to protruding out of a wall due to the fact that the hole edge parts need to be arranged for holing a steel plate of a traditional buckling-restrained steel plate shear wall, and the holed size of the steel plate is additionally increased are solved. The holed buckling-restrained shear wall comprises an upper frame beam, a lower frame beam, a left frame column, a right frame column, a plurality of plate bodies, two buckling-restrained fishplates and two holed steel plates; and the upper frame beam, the lower frame beam, the left frame column and the right frame column form a rectangular frame body, the two buckling-restrained fishplates are vertically installed in the rectangular frame body, the two holed steel plates are symmetrically arranged in the rectangular frame body, each holed steel plate is fixedly connected with one buckling-restrained fishplate, and each holed steel plate is fixedly connected with the inner side wall of the rectangular frame body through the multiple plate bodies.

Description

technical field [0001] The invention relates to a shear wall and a construction method, in particular to an open-hole anti-buckling shear wall with buckling restraint fishplates and a construction method. Background technique [0002] The buckling-resisted steel plate shear wall is a lateral force-resisting member obtained by setting restraint members outside the plane of the traditional non-stiffened steel plate shear wall. The buckling-resistant steel plate shear wall uses out-of-plane restraint members to restrain the buckling of the steel plate, so that the steel plate can resist the horizontal load in the in-plane shear state, thereby achieving the purpose of improving the mechanical performance of the structure. Buckling-resistant steel plate shear walls have the advantages of high rigidity, high bearing capacity, strong energy dissipation capacity, etc., and have excellent seismic performance, and are especially suitable for high-rise and super high-rise buildings. I...
