A double-layer steel plate composite shear wall with horizontally staggered I-shaped steel members with corrugated webs

Abstract

The invention relates to a double-layer steel plate composite shear wall with corrugated web I-shaped steel components transversely arranged in a staggered mode, and belongs to the field of structuralengineering. The combined shear wall is composed of a double-layer steel plate shear wall body formed by welding a plurality of first steel plate shear wall units and second steel plate shear wall units in a crossed mode and integrally-poured concrete. The corrugated web I-shaped steel components in the adjacent steel plate shear wall units are arranged in the length direction of outer side steelplates in a staggered mode, so that the buckling mode of a whole wall body is changed, then overall buckling of the wall body is changed into local buckling of a part of the wall body, and the bearing capacity is effectively improved; corrugated webs can be made high and thin, so that the elastic buckling loads of the plates among the cells are similar, and the economical efficiency of the steelplate shear wall is effectively improved; the corrugated webs are not unstable when being pressed, so that the connection performance of the corrugated web I-shaped steel components and the outer sidesteel plates when the wall body is pressed is effectively ensured; and the steel plate shear wall units are transversely arranged, so that the shear wall units are sequentially welded from bottom totop in the installation process, and the construction difficulty is reduced.

Description

technical field [0001] This patent relates to a double-layer steel plate composite shear wall with corrugated web I-shaped steel members arranged in a horizontal and staggered manner, 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 l...
