摘　　要：钢框架内填钢筋混凝土剪力墙(SRCW)是由钢框架和钢筋混凝土剪力墙通过抗剪连接件组合而形成的抗侧力构件。实际工程中,往往不可避免的要对墙板开洞,然而对开洞SRCW墙板的抗剪承载力还鲜有研究。文章基于ABAQUS建立了钢框架内填开方形洞口钢筋混凝土剪力墙有限元模型,对钢框架内填开方形洞口钢筋混凝土剪力墙在单调水平荷载下的反应进行了弹塑性分析,研究了开方形洞口钢筋混凝土剪力墙各组成构件的协同工作机理及墙板参数变化对开方形洞口钢筋混凝土剪力墙抗剪承载力的影响。Steel frame filled reinforced concrete shear wall(SRCW)is a new structure system.In actual engineering,it is often unavoidable to open a hole in the wall plate.However,the shear bearing capacity of SRCW with an opening is rarely studied.In this paper,based on the ABAQUS software,the finite element model of SRCW with and without square opening on reinforced concrete slab is built,and the elastoplastic analyses of the response of SRCW under monotonic horizontal load are performed.The cooperative working mechanism and the shear bearing capacity of the components in the SRCW,and the effects of design parameters of the reinforced concrete slab with square opening,are studied.
