A cold-formed steel embedded double corrugated steel plate shear wall

Abstract

The invention discloses a shear wall with double corrugated steel plates embedded in cold-formed steel, which comprises two corrugated steel plates, an upper steel girder, a lower steel girder and two cold-formed thin-walled steel end columns, the upper steel girder and the lower steel girder are both It is composed of two L-shaped angle steel back to back. The upper ends of the two corrugated steel plates are embedded between the two L-shaped angle steels of the upper steel beam, and the lower ends of the two corrugated steel plates are embedded between the two L-shaped angle steels of the lower steel beam. The two corrugated steel plates are located on the central axis of the shear wall. The corrugated steel plates and the L-shaped angle steel are connected by connecting pieces that run through the two L-shaped angle steels and the two corrugated steel plates. The two corrugated steel plates are connected by connecting pieces. Through the connection, the two sides of the two corrugated steel plates are respectively connected with two cold-formed thin-walled steel end columns. The cold-formed steel embedded double corrugated steel plate shear wall has high buckling bearing capacity, small out-of-plane deformation, low noise when the steel plate buckles, and can be modularized for construction and installation, convenient for construction and installation, good in integrity and continuity, and shear resistant. Good 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...

AI Technical Summary

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 in the earthquake

When the steel plate buckles, a lot of noise is generated, which affects the user experience

In terms of wall modularization, most walls are connected and fixed by panels or angle steel at the corners. The continuity and integrity of the walls are weak. Under the action of lateral force, the corners are easily damaged.

Due to the above reasons, the traditional cold-formed steel shear wall is not conducive to the application in engineering
