Dog-bone type coupled shear wall with end plates, bolts and steel coupling beams

Abstract

The invention provides a dog-bone type coupled shear wall with end plates, bolts and steel coupling beams. Steel structures are embedded in concrete shear walls, the steel coupling beams are connected with steel columns of the embedded steel frames by the end plates and the bolts, sections, which are close to ends of edges of the shear walls, of the steel coupling beams are locally reduced, and a 'dog-bone type' structure is formed. The dog-bone type coupled shear wall aims to realize connection among the steel coupling beams and the shear walls, anti-seismic and energy dissipation performances of the steel coupling beams are improved, the steel frames are embedded in the shear walls, the steel coupling beams are connected with the columns of the steel frames by the end plates and the bolts, the sections of the ends of the steel coupling beams are reduced with local ranges, and the 'dog-bone type' structure is formed. Accordingly, the steel coupling beams and the concrete shear walls are connected effectively, construction is carried out simply and conveniently, design and analysis are simple, the energy dissipation and anti-seismic performances of the steel coupling beams are strengthened, and an anti-seismic performance of a coupled shear wall system is enhanced.

Description

technical field [0001] The invention relates to the anti-seismic technology of high-rise building structures, in particular to a dog-bone type end plate bolt steel connecting beam combined limb shear wall used for high-rise buildings. Background technique [0002] my country has a large population, and building land resources are increasingly scarce. High-rise and super high-rise structures will increasingly become the mainstream of urban architecture in my country. The combined shear wall structure is a lateral force resistant structural system that couples two or more single-leg shear walls to resist horizontal loads, especially earthquakes, through connecting beams. It is widely used in high-rise and super high-rise buildings in China. . When a moderate-intensity earthquake or a large earthquake occurs, the seismic energy is mainly dissipated by forming a plastic hinge at the end of the coupling beam and the bottom of the shear wall, and the coupling beam should first en...

Problems solved by technology

[0006] The reinforced concrete coupling beams used for traditional combined shear walls cannot meet the ductility requirements of the structure, while the traditional connection methods of new steel coupling beams or steel-concrete composite coupling beams and concrete shear walls have complex structures and construction technical requirements. high and difficult, and difficult to analyze and design, the purpose of the present invention is to provide a new type of combined shear wall with convenient construction, simple analysis and design, and better seismic performance
