摘　　要：通过对4片钢筋混凝土开洞叠合剪力墙和2片普通钢筋混凝土开洞剪力墙进行抗震性能试验研究,对比研究了试件的受力全过程、开裂部位、裂缝发展情况以及破坏形态,分析了试件的承载能力、滞回曲线、骨架曲线、刚度退化曲线、延性性能、耗能能力等。研究结果表明:钢筋混凝土开洞叠合剪力墙的受力性能基本和普通钢筋混凝土开洞剪力墙相同,具有较好的抗震性能;保温层外侧的预制钢筋混凝土板能够协同参与受力,与普通钢筋混凝土开洞剪力墙相比,其承载力可提高约7%,并可有效降低其刚度退化;剪式支架能使钢筋混凝土开洞叠合剪力墙的预制部分与现浇混凝土形成整体,共同参与工作。Quasi-static tests on four reinforced concrete composite shear walls with opening and two reinforced concrete shear walls with opening under cyclic loading were reported. The deformation properties, failure mode were discussed, and the bearing capacity, hysteretic loops, skeleton curves, rigidity degradation curves, ductility and energydissipation were investigated. Test results indicate that the mechanical behavior of the reinforced concrete composite shear walls with opening is the same as that of the reinforced concrete shear walls with opening. The study shows that the reinforced concrete composite shear walls with opening have good seismic behavior. The prefabricated reinforced concrete cover for the thermal insulation can provide a certain extent of load carrying capacity, and the bearing capacity of the reinforced concrete composite shear walls with opening is higher than that of the reinforced concrete shear walls with opening about 7%. The prefabricated parts and the cast-in-situ concrete parts of the reinforced concrete composite shear walls with opening can work together in coordination very well under loading.
