Problems solved by technology

The method of welding stiffeners requires a lot of welding work on the steel plate, which leads to welding residual stress and deformation on the steel plate surface before installation
The prefabricated concrete anti-buckling cover slab is installed on the steel plate by pulling bolts to avoid the influence of welding problems. However, the concrete cover slab needs to bind steel bars, make formwork, pour conc

Abstract

The invention provides an all-steel fabricated double-limb steel pipe constrained anti-buckling steel plate shear wall, and belongs to the technical field of structural engineering. An embedded steelplate is welded in an edge frame through an upper splice bar, a lower splice bar, a left splice bar and a right splice bar, double-limb constraint steel pipes are arranged at equal intervals on the two faces of the embedded steel plate, and the embedded steel plate is clamped through connecting bolts. According to the all-steel fabricated double-limb steel pipe constrained anti-buckling steel plate shear wall, the shear bearing capacity and the hysteresis energy consumption capability of the steel plate shear wall are improved, the bearing capacity and rigidity of the shear wall can be conveniently adjusted by adjusting the number of the double-limb constraint steel pipes, and the structural design is facilitated; the constraint steel pipes are small in size, light in self weight and convenient to transport and hoist.

Description

technical field [0001] The invention relates to a buckling-resistant steel plate shear wall constrained by all-steel assembled double-leg steel pipes, and belongs to the technical field of structural engineering. Background technique [0002] Buckling-resistant steel plate shear walls are the most commonly used lateral force-resisting members in high-rise buildings. The out-of-plane buckling deformation of steel plates is restrained by setting restrained buckling members outside the plane, and the mechanical properties of shear steel plates are improved. Because of its high initial rigidity, high bearing capacity, high ductility coefficient, stable hysteretic energy consumption and other performance advantages, it is favored by the majority of engineering and technical personnel. At present, the commonly used out-of-plane restraint construction methods of buckling-resistant steel plate shear walls in engineering include welding stiffeners and installing concrete buckling-res...
