A corrugated steel wall with dissipative corners

Abstract

The invention relates to a corrugated steel plate wall with energy-dissipating corners, including a corrugated steel plate wall. The corrugated steel plate wall is composed of an integrated peripheral flat steel plate and a central corrugated steel plate. The two sides of the peripheral planar steel plate are respectively fixed with corresponding edge columns, the edge columns are square steel tube concrete column components, and the square steel tube concrete column components are formed by filling concrete inside rectangular cold-formed hollow steel sections , the left and right sides of the peripheral planar steel plate are respectively welded to the inner side of the corresponding rectangular cold-formed hollow section steel, and the upper and lower ends of the rectangular cold-formed hollow section steel are respectively integrally provided with a set of corresponding end plates, and the end plates The plates are respectively fixedly connected to the connection plates affixed to the frame beams through corresponding energy dissipation keys. The present invention can effectively deal with vertical force and transverse force simultaneously without excessive deformation, and can effectively prevent tearing of corner joints.

Description

technical field [0001] The invention relates to a corrugated steel plate wall, in particular to a corrugated steel plate wall with energy-dissipating corners. Background technique [0002] Existing steel plate walls generally use flat steel plates. Since the out-of-plane stiffness of flat steel plates is very small, out-of-plane buckling will occur under the action of a small horizontal force, resulting in low stiffness and limited hysteretic performance. After the earthquake, the steel plate wall is prone to deformation. If the deformation is not serious, some repair work is required before it can be reused. However, if the deformation is serious, it cannot be repaired and the built-in steel plate needs to be replaced. Replacing the built-in steel plate, firstly, the replacement operation is difficult, and secondly, it will lead to a large increase in cost. At present, the most common way to solve this problem is to use out-of-plane restraint plates or stiffeners to increa...

Problems solved by technology

In addition, during the stress process of the entire non-buckling corrugated steel plate energy-dissipating wall, the maximum stress generally occurs at the corner, and stress concentration is prone to occur, which will eventually lead to tearing of the corner connection and cause the non-buckling corrugated steel plate energy-dissipating wall to fail
