【摘要】：为研究预制钢筋混凝土叠合剪力墙的抗震性能,对3片预制钢筋混凝土叠合剪力墙、1片现浇钢筋混凝土剪力墙进行低周反复荷载试验,对比研究了各试件的荷载-位移曲线、骨架曲线、刚度退化规律、延性性能、耗能能力和破坏形态等,探讨了叠合墙体预制部分与现浇部分的协同工作性能,以及不同施工工艺对整体工作性能的影响。研究结果表明:1)墙体破坏以剪切破坏为主;2)预制叠合墙和现浇墙体的承载能力、破坏模式、抗震性能指标均相近;3)预制试件的预制面与现浇面交接处未出现竖向劈裂裂缝,受力变形基本同步,协同工作性能良好;4)不同施工工艺对叠合墙的承载和变形性能无明显影响。
[Abstract]:In order to study the seismic behavior of prefabricated reinforced concrete composite shear wall, three prefabricated reinforced concrete composite shear walls and one cast-in-situ reinforced concrete shear wall were subjected to low-cycle repeated load tests, and the load-displacement curves of each specimen were compared and studied. Skeleton curve, stiffness degradation rule, ductility, energy dissipation ability and failure form are discussed. The synergistic working performance of prefabricated part and cast-in-place part of superimposed wall and the influence of different construction technology on overall working performance are discussed. The results show that the failure of wall is mainly shear failure) the bearing capacity, failure mode and seismic performance index of prefabricated composite wall and cast-in-place wall are close to each other (3) there is no vertical split crack at the interface between prefabricated surface and cast-in-place surface of prefabricated specimen. The mechanical deformation is basically synchronous and the cooperative working performance is good. (4) different construction techniques have no obvious influence on the bearing capacity and deformation performance of the composite wall.
