Corrugated steel plate wall with power-wasting corner

Abstract

The invention relates to a corrugated steel plate wall with a power-wasting corner. The corrugated steel plate wall with the power-wasting corner comprises a corrugated steel plate wall body, the corrugated steel plate wall body is composed of a peripheral plane steel plate and a central corrugated steel plate which are integrally formed, corrugated tracks of the central corrugated steel plate isin a regular oval shape, corresponding edge columns are fixedly connected to the two sides of the peripheral plane steel plate correspondingly and are concrete-filled square steel tubular column components, the concrete-filled square steel tubular column components are formed by rectangular cold-formed hollow profile steel filling with concrete, the left side and the right side of the peripheral plane steel plate are welded to the inner side faces of the corresponding rectangular cold-formed hollow profile steel correspondingly, the upper end and the lower end of the rectangular cold-formed hollow profile steel are integrally provided with a set of corresponding end plates, and the end plates are fixedly connected to connecting plates fixedly connected to a frame beam through correspondingenergy wasting keys correspondingly. According to the corrugated steel plate wall, vertical stress and transverse stress can be effectively coped with at the same time without generating excessive deformation, and corner connection tearing can be effectively prevented.

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
