A double-layer steel plate composite shear wall with corrugated web I-shaped steel members truss-tie

Abstract

The invention relates to a double-layer steel plate combined shear wall with corrugated web plate I-shaped steel components in truss type binding, and belongs to the field of structure engineering. According to the combined shear wall, multiple steel plate shear wall units are firstly welded to form a pure steel plate wall, and then concrete is poured between steel plates to form the double-layersteel plate combined shear wall with the corrugated web plate I-shaped steel components in truss type binding. The corrugated web plate I-shaped steel components are applied into the wall structure, the buckling mode of the whole wall is changed, overall buckling of the wall becomes into partial buckling of part of the wall, and bearing force is effectively improved. The corrugated web plate I-shaped steel components are introduced into the double-layer steel plate combined shear wall, web plates of the corrugated web plate I-shaped steel components and outer steel plates directly participatein the resisting side of the shear wall, meanwhile, flanges of the corrugated web plate I-shaped steel components achieve an obvious binding function on the outer steel plates, and the anti-shear bearing force of the wall is improved. A truss type structure is formed by the outer steel plates, the corrugated web plate I-shaped steel components and tie bars, and the overall stability of the wall isenhanced.

Description

technical field [0001] The patent relates to a double-layer steel plate composite shear wall with truss-type tie knots of I-shaped steel members with corrugated webs, belonging 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 resistan...

Problems solved by technology

[0005] On this basis, in order to overcome the shortcoming of out-of-plane buckling of the double-layer steel composite wall, further enhance the bearing capacity and energy dissipation capacity of the double-layer steel composite wall, improve the buckling mechanism of the double-layer steel composite wall, and realize the construction of steel structure houses. At the same time, based on the concept of improving the elastic shear buckling load of the shear wall and its shear bearing capacity, this patent proposes a double-layer steel plate composite shear wall with corrugated web I-shaped steel members truss-type tie
