摘　　要：研究钢筋混凝土无洞叠合剪力墙的抗震性能。对4片钢筋混凝土无洞叠合剪力墙和2片钢筋混凝土普通剪力墙分别进行了低周反复荷载试验,对比研究试件的受力全过程、开裂部位、裂缝发展情况以及破坏形态,分析试件的承载能力、滞回曲线、骨架曲线、刚度退化曲线、延性性能等抗震性能。研究表明:钢筋混凝土叠合剪力墙的受力性能与钢筋混凝土普通剪力墙类似,具有较好的抗震性能,剪式支架能使钢筋混凝土叠合剪力墙的预制部分与现浇混凝土形成整体,共同工作,承受外部荷载。The seismic behavior of composite reinforced concrete shear walls without opening was studied.Pseudo-static tests were conducted under cyclic loading on four composite reinforced concrete shear walls without opening and two reinforced concrete shear walls.Deformation property failure mode,bearing capacity,hysteretic loop,skeleton curve,ductility,and energy-dissipation were investigated.Testing results indicated that the mechanical behavior of the composite reinforced concrete shear wall was the same as that of the reinforced concrete shear wall.The study showed that the composite reinforced concrete shear wall had good seismic behavior.The prefabricated parts and the cast-in-situ concrete parts of the composite reinforced concrete shear wall could work together well under loading.
