Built-in perforated steel plate composite shear wall

Abstract

The invention relates to a built-in perforated steel plate composite shear wall, which comprises a perforated steel plate, reinforcing meshes are arranged on two sides of the plate surface of the perforated steel plate, a plurality of holes are uniformly distributed in the plate surface of the perforated steel plate, tie bars are connected in the holes in a penetrating manner, two ends of each tie bar are respectively connected with the reinforcing meshes on two sides, the tie bars, the perforated steel plates and the reinforcing meshes form a structural framework, and the structural framework is subjected to one-time pouring in a cast-in-place concrete mode till the two sides are filled to form concrete slabs. The distribution of a tension field is adjusted mainly through the perforated steel plates, the cooperative work capacity of the steel plate tension field and a concrete plate pressure field is enhanced, the lateral stiffness, energy dissipation capacity and ductility of the combined shear wall are greatly improved, meanwhile, the defect that the pouring process of a traditional stud combined shear wall is tedious is overcome, the construction efficiency is improved, the structure is simple, cost is low, and construction is convenient and efficient, performance is remarkably improved, and the built-in perforated steel plate composite shear wall is suitable for lateral resistance and energy consumption improvement of engineering structures.

Description

Technical field [0001] The present invention relates to the field of civil engineering combined structures, and in particular, there is a built-in steel sheet combination shear wall. Background technique [0002] With the improvement of the development and construction technology of the state, my country's high-rise buildings are steadily advanced in terms of high height and superior power performance. Also accompanying the height of the building, the structure is getting higher in response under lateral effects of earthquake, wind, and even the collapse of the anti-side capacity or the lack of energy consumption, seriously affects the use and operation safety of high-rise buildings. . my country is also an earthquake, Taiwan (hurricane), has a natural disaster, effectively enhancing the anti-side capacity of high-rise buildings is the technical problem to be solved. [0003] In recent years, domestic and foreign scholars have promoted the extensive research from all kinds of she...

Problems solved by technology

The traditional combined shear wall is a thin steel plate with studs welded inside, and the studs are used as shear connectors to connect with the reinforced concrete slabs on both sides. In addition to the residual stress and initial defects, there is still the problem of steel plate failure and tearing; on the other hand, once the concrete is crushed and peeled off, the connection between the reinforced concrete slab and the studs will be destroyed, and the later buckling restraint of the concrete slabs on both sides will be lost. Moreover, when the force is applied, the tensile field of some steel plates with or without openings is not orthogonal to the pressure field of the concrete slab, and the efficiency of coordinative force bearing is low. At the same time, the construction of such combined shear walls is also relatively cumbersome. Reinforced concrete slabs need to be poured in batches on both sides, which will also cause the problem of asymmetric center of gravity
