Finite Element Analysis of Performance  of Steel Plate Concrete CompositeShear Wall-Steel Beam Joint Based on Prefabricated Cross U-Shaped Connector

Abstract

Abstract: In order to study the mechanical properties of steel plate concrete composite shear wall-steel beam joint based on prefabricated cross U-shaped connector,numerical simulation of the joint model under uniaxial load and low cyclic loading was carried out using the refined general finite element software ABAQUS 6.14.The influences of U-shaped plate thickness,U-shaped plate length and steel beam span-to-height ratios on mechanical properties of the joint were discussed.The results show that the steel plate concrete composite shear wall-steel beam joint based on prefabricated cross U-shaped connector has good plastic deformation capacity and tensile bearing capacity.Each joint model has good hysteresis performance and energy dissipation capacity,and the equivalent viscous damping coefficient is between 0.302 9 and 0.400 1.The U-shaped plate length has no obvious influence on the initial stiffness and energy dissipation of the joint.The ductility and energy dissipation of the joint model perform well when the thickness of the U-shaped plate is about 12 mm.With the increase of span-to-height ratios of steel beam,the rotational stiffness and ductility as well as the energy dissipation capacity of the joint are significantly improved.

Key words: prefabricated, steel plate concrete composite shear wall, cross U-shaped connector, mechanical property, nonlinear finite element
