摘　　要：通过对3片钢筋混凝土水平拼接叠合剪力墙、1片钢筋混凝土整体叠合剪力墙和1片钢筋混凝土全现浇剪力墙进行抗震性能试验研究,对比研究了试件的裂缝发展情况及破坏形态,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、耗能性能等。研究结果表明:水平拼接叠合剪力墙与整体叠合剪力墙以及全现浇剪力墙的受力过程、破坏模式基本相同,抗震性能指标相近,具有较好的抗震性能;水平拼接节点构造合理,水平拼接叠合剪力墙的承载能力不低于整体叠合剪力墙;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,协同工作承受外部荷载。Quasi-static tests on three reinforced concrete composite shear walls with level splice and one reinforced concrete composite shear wall without level splice under cyclic loading were reported. Quasi-static test on one reinforced concrete shear wall under cyclic loading was reported too. The deformation properties and failure mode were discussed. The bearing capacity, hysteretic loops, skeleton curves, ductility and energy-dissipation were analyzed. Test results indicate that the mechanical behavior of the reinforced concrete composite shear walls with level splice and the reinforced concrete composite shear wall without level splice is the same as that of the reinforced concrete shear wall. The study shows that the reinforced concrete composite shear walls with level splice have good seismic behavior. The detailing requirements of the level splice are reasonable, and the load-carrying capacity of the reinforced concrete composite shear walls with level splice is greater than that of the reinforced concrete composite shear wall without level splice. The prefabricated parts and the east-in-situ concrete parts of the reinforced concrete composite shear walls can work together very well under loading.
