Abstract

Opening anti-buckling shear wall with buckling restraint fishplate and construction method thereof. The present invention relates to a shear wall and a construction method. The purpose of the present invention is to solve the problem that openings of steel plates in traditional anti-buckling steel plate shear walls need to be provided with openings. The edge member increases the opening size of the steel plate, which leads to the weakening of the structure's seismic performance and the reduction of bearing capacity, and the problem that the edge member of the opening is easy to protrude from the wall. It includes the upper frame beam, the lower frame beam, the left frame column, and the right frame. columns and multiple plate bodies, it also includes two buckling-constrained fishplates and two open-hole steel plates; the upper frame beam, lower frame beam, left frame column and right frame column form a rectangular frame body, and two The plate is vertically installed in the rectangular frame, and two holed steel plates are symmetrically arranged in the rectangular frame, and each holed steel plate is fixedly connected with a buckling restraint fishplate, and each holed steel plate is connected to the rectangular frame through multiple plates. The inner wall of the frame body is fixedly connected. The invention belongs to the field of building structures.

Description

technical field [0001] The invention relates to a shear wall and a construction method, in particular to an open-hole buckling-resistant shear wall with a buckling restraint fishplate and a construction method. Background technique [0002] The anti-buckling steel plate shear wall is a kind of lateral force resistance member obtained by setting the restraint members out of the plane of the traditional non-stiffened steel plate shear wall. The anti-buckling 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 state of in-plane shear, thereby achieving the purpose of improving the mechanical performance of the structure. The anti-buckling steel plate shear wall has the advantages of high rigidity, high bearing capacity, strong energy dissipation capacity, etc., and has excellent seismic performance, especially suitable for high-rise and super high-rise buildings.
