摘　　要：钢板外包混凝土组合剪力墙(C-SPW)是一种新型抗侧力墙板,其内嵌钢板和外包混凝土板通过栓钉连接,混凝土板对钢板提供面外约束作用,延迟内嵌钢板剪切屈曲。实际工程中,往往不可避免的要对墙板开洞,然而对有洞口C-SPW还鲜有研究。为研究开洞口C-SPW的抗剪性能,文章就方形洞口对C-SPW抗剪承载力的影响进行了有限元模拟及分析。Composite steel plate shear wall(C-SPW)consisting of steel plate with reinforced concrete encasement on one or both sides of the steel plate using headed studs is an effective lateral load resisting system.In actual engineering,it is often unavoidable to open a hole in the wall plate,but there is little research on the C-SPW with a hole.In order to study the shear performance of the opening C-SPW,a finite element simulation and analysis of the influence of the square opening on the shear capacity of the C-SPW is performed.

关 键 词：组合剪力墙 有限元分析 抗剪承载力 方形洞口
