摘要: 装配式剪力墙高层住宅结构的抗震可靠性是我国建筑工业化顺利实现的重要要求,为掌握装配式叠合连梁在装配式剪力墙高层结构中的力学性能,对装配式剪力墙空间子结构模型进行了低周反复试验。通过试验测试掌握了装配式叠合连梁的裂缝分布规律和破坏模式,并分析了装配式叠合连梁构件对装配式剪力墙空间子结构抗震性能的影响规律。最后根据试验实测和分析结果,对装配式叠合连梁的合理设计给出了建议。Abstract: The seismic reliability of resident buildings constructed by prefabricated high-rise shear walls is one of the important requirements for the achievement of construction industrialization in China. To deeply understand the mechanical properties of superposed RC coupling beams in prefabricated shear wall structures, the quasi-static loading experiment was conducted on a sub-structure model spatial prefabricated shear wall. By the experiment test, the crack development laws and failure modes of the model were observed, and the influence laws of superposed coupling beams on the seismic performances of the sub-structures for the prefabricated shear walls were analyzed. Finally, according to the observed and analyzed results, the suggestions for reasonable design of superposed coupling beams were proposed.
