Corrugated web I-shaped steel tie double-layer steel plate composite wall

Abstract

The invention relates to a double-layer steel plate composite shear wall with corrugated web I-shaped steel members tied, and belongs to the field of structural engineering. The composite shear wall is composed of a double-layer steel plate shear wall formed by welding a plurality of steel plate shear wall units with corrugated web I-shaped steel members and integrally poured concrete. Each steelplate shear wall unit is formed by welding two front-back symmetrical outer side steel plates and one corrugated web I-shaped steel member with the length equal to that of the outer side steel plates.The web width of the corrugated web I-shaped steel members can be remarkably larger than the horizontal spacing of the corrugated web I-shaped steel members, elastic buckling loads of plates betweencells are similar, and the economical efficiency of the steel plate shear wall is effectively improved. Corrugated webs in the corrugated web I-shaped steel members only bear lateral force in the wallstress process and basically do not bear vertical force, compared with flat webs, the corrugated webs cannot lose stability when being pressed, the connecting performance of the corrugated web I-shaped steel members and the outer side steel plates is effectively guaranteed, and the overall stability is remarkably improved.

Description

technical field [0001] The patent relates to a corrugated web I-shaped steel tie-bonded double-layer steel plate composite wall, which belongs to the field of structural engineering. Background technique [0002] With the continuous development and progress of economic level, technological level and architectural level, my country's architectural structure is also showing an increasingly complex development trend, and the height of buildings is increasing day by day. High-rise and super high-rise buildings are more common in major cities. 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. [0003] The steel plate composite wall structure is a new type of lateral force resistance structure system developed in t...
