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

Abstract

The invention relates to a double-layer steel plate combined shear wall for binding of corrugated web I-steel members in staggered arrangement, and belongs to the field of structural engineering. Thecombined shear wall consists of a double-layer steel plate shear wall and integrally poured concrete, wherein the double-layer steel plate shear wall is formed by a plurality of first steel plate shear wall units and a plurality of second steel plate shear wall units through crossed welding shaping. The corrugated web I-steel members in the adjacent steel plate shear wall units are in staggered arrangement in the length direction of an outer side steel plate; the integral buckling mode of the wall is changed; and the integral buckling of a wall body is changed into local buckling of the partial wall body units, so that the bearing force is effectively improved. A corrugated web cannot generate unstability when being pressed; the connection performance of corrugated webs and wing edges whenthe wall body is pressed is effectively ensured; the connection performance of the corrugated web I-steel members and the outer side steel plate is further ensured; and the integral stability of thestructure is obviously improved. The corrugated webs can be made to be high and thin, so that elastic buckling loads of plate members between unit lattices can be similar, and the economical efficiency of a steel plate shear wall is effectively improved.

Description

technical field [0001] The patent relates to a double-layer steel plate composite shear wall with staggered arrangement of I-shaped steel members with corrugated webs, 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 res...
