Cold-bend steel embedded double corrugated steel plate shear wall

Abstract

The invention discloses a cold-bend steel embedded double corrugated steel plate shear wall. The cold-bend steel embedded double corrugated steel plate shear wall comprises two corrugated steel plates, an upper steel beam, a lower steel beam, and two cold-bend thin-walled steel end posts. Both of the upper steel beam and the lower steel beam are formed by two L-shaped angle steels in a back-to-back mode. The upper ends of the two corrugated steel plates are arranged between the two L-shaped angle steels of the upper steel beam in an embedded mode. The lower ends of the two corrugated steel plates are arranged between the two L-shaped angle steels of the lower steel beam in an embedded mode. The two corrugated steel plates are located on the central axis of the shear wall. The corrugated steel plates are connected with the L-shaped angle steels through connecting pieces penetrating through the two corrugated steel plates and the L-shaped angle steels. The two corrugated steel plates connected with each other through the connecting pieces in a penetrated mode. The cold-bend thin-walled steel end posts are respectively connected with the two sides of the two corrugated steel plates. The cold-bend steel embedded double corrugated steel plate shear wall is high in buckling bearing capacity, relatively small in deformation outside a plane, low in noise when the steel plates are buckling. The shear wall can also be installed in the modular mode, and is convenient in construction and installation with good integrity, continuity, shear strength, and lateral stiffness.

Description

technical field [0001] The invention relates to the technical field of building steel structures in civil engineering, in particular to a cold-formed steel embedded double corrugated steel plate shear wall suitable for prefabricated steel structure buildings. Background technique [0002] Cold-formed steel structures have the advantages of low construction cost, light weight, high strength, environmental protection, and easy installation, and are widely used in North America, Australia, Japan and other countries. At present, low-rise cold-formed steel structure buildings are mainly used in residential buildings, villas, apartment-type houses below three floors, and commercial buildings. [0003] As we all know, my country has a large population, a small per capita land area, a shortage of land resources, and excess steel structure capacity. At present, China is in the stage of rapid development of prefabricated structures and rural urbanization. Therefore, it is more importa...

Problems solved by technology

However, the steel plate shear wall has a large width-to-thickness ratio or height-to-thickness ratio, which makes the steel plate prone to out-of-plane buckling instability under the action of horizontal lateral force, which affects its bearing capacity; The adverse effects of the edge components will also lead to a serious pinch effect on the hysteretic curve of the steel plate shear wall, which is not conducive to the energy dissipation of the wall
