摘要/Abstract

摘要： 为了深入研究基于装配式交叉U型连接件的钢板混凝土组合剪力墙-钢梁节点的力学性能,采用精细化通用有限元软件ABAQUS 6.14对基于装配式交叉U型连接件的钢板混凝土组合剪力墙-钢梁节点模型进行了单调荷载和低周反复荷载作用下的数值模拟,研究了U型板厚度、U型板长度以及钢梁跨高比对该节点力学性能的影响。结果表明:基于装配式交叉U型连接件的钢板混凝土组合剪力墙-钢梁节点具有良好的塑性变形能力和抗拉承载力,各节点模型的滞回性能良好,等效粘滞阻尼系数在0.302 9~0.400 1之间,具有良好的耗能能力;U型板长度对节点初始刚度和能量耗散影响不明显;U型板厚度在12 mm左右时,节点模型的延性及耗能能力均表现良好;随着钢梁跨高比的增加,节点的转动刚度增加,耗能能力显著提高,延性增加。

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
