Abstract

The invention relates to a modularized fabricated double-steel-plate shear wall, and belongs to the field of structural engineering. The double-steel-plate shear wall is formed by welding two edge columns and an integral steel plate shear wall unit. Based on the concept of improving the elastic shear buckling load and the shear bearing capacity of the shear wall, inner stiffening units are arranged to conduct buckling constraint on outer side steel plates, and the bearing capacity and out-of-plane rigidity of the double-steel-plate shear wall are improved. The machining of the inner stiffening units and the assembly of the double-steel-plate shear wall can both adopt mature processes, and the machining difficulty is greatly reduced compared with that of a traditional double-steel-plate shear wall.

Description

technical field [0001] This patent relates to a modular assembly type double-steel plate shear wall, which belongs to the field of structural engineering. Background technique [0002] With the increasing height of buildings, horizontal loads have gradually replaced vertical loads as an important control factor in the design of high-rise buildings. Traditional lateral force-resistant components can no longer meet the needs of high-rise buildings for energy dissipation and horizontal bearing capacity. The steel plate shear wall structure is a new type of lateral force-resisting structural system developed in the 1970s. It has become a structure favored by many designers because of its extremely high bearing capacity, stable energy dissipation capacity and good ductility. [0003] However, due to the large height-to-thickness ratio or width-to-thickness ratio, the steel plate shear wall is prone to local out-of-plane buckling, which affects its bearing capacity. When the stee...
