摘　　要：为研究边缘柱为部分外包混凝土组合柱的钢板剪力墙结构(弱轴连接)的抗震性能,使用有限元软件ABAQUS完成1榀边缘柱为H型钢柱、5榀边缘柱为PEC柱的钢板剪力墙结构(弱轴连接)在循环荷载作用下的有限元数值模拟,得到结构的应力分布、破坏模式、滞回曲线、耗能性能、骨架曲线以及刚度退化曲线,并完成了1榀带PEC柱的钢板剪力墙结构(弱轴连接)的试验,验证了有限元模拟的正确性.分析表明在钢板剪力墙结构中(弱轴连接),将PEC柱作为剪力墙的边缘框架柱,同样可以很好的约束屈曲后的钢板剪力墙,使其充分发挥屈曲后的性能,显著提升整体结构的抗侧刚度、承载力以及耗能性能.In order to study the seismic performance of steel plate shear wall structures(weak axis connection)with partially encased concrete composite columns,a numerical simulation of one steel plate shear wall structure with H-shaped edge column and five steel plate shear wall structures with PEC column(weak axis connection)under cyclic loading was conducted using the finite element software ABAQUS.The stress distribution,failure mode,hysteretic curve,energy dissipation performance,skeleton curve,and stiffness degradation curve of the structure are obtained.Additionally,a test of a steel plate shear wall structure with a PEC column(weak axis connection)was performed to validate the finite element model.The analysis shows that in the steel plate shear wall structure(weak axis connection),taking the PEC column as the edge frame column of the shear wall effectively restrains the steel plate shear wall after buckling,making it give full play to the post buckling performance,and significantly improving the lateral stiffness,bearing capacity,and energy dissipation performance of the whole structure.
