Modified double-layered steel plate concrete shear wall and construction method thereof

Abstract

The invention discloses a modified double-layered steel plate concrete shear wall and a construction method thereof. The modified double-layered steel plate concrete shear wall comprises two layers of steel plates and a concrete wall body disposed between the two layers of steel plates. Binding bars are connected between the two layers of steel plates. Reinforcing bars are disposed on each steel plate. Two ends of each binding bar penetrate through the reinforcing bars and the steel plates. The binding bars, the reinforcing bars and the steel plates are connected with one another. By disposing the binding bars and the reinforcing bars, binding capability of the steel plates to core concrete is improved and buckling and developing of areas among the binding bars are delayed and blocked. When the binding bars are threaded and the reinforcing bars are connected with the steel plates through spot-welding connection, bolt connection or a combination of spot-welding connection and bolt connection, influences of welding residual stress can be relieved, construction is simple and easy, thickness of the steel plates can be reduced evidently, welding processes can be omitted or reduced greatly, and construction cost can be lowered.

Description

technical field [0001] The invention relates to building structures, in particular to an improved double-layer steel plate concrete shear wall and a construction method thereof. Background technique [0002] Steel tube concrete structure, steel plate concrete shear wall and other structures effectively combine the advantages of steel and concrete, and have the advantages of high bearing capacity, good plasticity, superior earthquake resistance and fire resistance, material saving and simple construction. The application of steel tube concrete columns and steel plate concrete shear walls in high-rise buildings, especially super high-rise buildings, has obvious advantages. [0003] The circular steel pipe concrete column provides uniform pressure on the inner filling concrete along the circumferential direction (see figure 1 ), while the confinement effect of the steel plate on the inner concrete of the rectangular steel tube concrete column (double-layer steel plate concrete...

Problems solved by technology

[0005] However, the above technical solution still has the following disadvantages: the area between the restraint rods is still prone to elastic-plastic local buckling phenomenon, and once buckling deformation occurs locally, the buckling deformation will bypass the strong restraint area of ​​the restraint rods and pass through the gap between the restraint rods. Gap spread and spread
