摘    要:对4片新型预制叠合剪力墙、2片钢筋混凝土全现浇剪力墙进行抗震性能试验研究。对比研究试件的裂缝发展情况及破坏形态,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、耗能性能等。研究结果表明:新型预制叠合剪力墙与全现浇剪力墙的受力过程、破坏模式基本相同,各抗震性能指标也基本形同,具有较好的抗震性能;新型预制叠合剪力墙的承载能力不低于全现浇剪力墙的承载能力,实现了与全现浇剪力墙受力性能相同的目标。

Abstract: Pseudo-static tests on four new type reinforced concrete composite shear walls under cyclic loading were reported. Pseudo-static tests on two reinforced concrete shear walls under cyclic loading were also reported. The deformation properties and failure mode were discussed. The bearing capacity, hysteretic loops, skeleton curves, ductility and energy-dissipation were analyzed. The results indicate that the mechanical behavior of new type reinforced concrete composite shear walls is the same as that of the reinforced concrete shear wall. The new type reinforced concrete composite shear walls have good seismic behavior. The loading-carrying capacity of new type reinforced concrete composite shear walls is not lower than that of the reinforced concrete shear wall. The goal of reinforced concrete composite shear wall equivalent cast-in-situ reinforced concrete shear wall is achieved.
