A new type of connection between shear walls is proposed for the shear wall with precast concrete hollow molds (PCHM). The overlapping reinforcements are inserted into the PCHM before pouring concrete into the hollow in this method. Full-scale test specimens are tested under low cyclic loading test to analyze their seismic performance, such as failure modes, hysteretic characters, stiffness degradation, energy dissipation, and ductility. For the precast specimen, although the penetrating crack appears at the horizontal connection, there is no large slippage leading to anchorage failure and disengagement of interfaces. Generally, compared with cast-in-situ shear walls, shear walls with PCHM have no large difference in bearing capacity, failure mode, stiffness degradation, energy dissipation and ductility. Therefore, the proposed shear wall with the new type of connection method is worth popularizing and utilizing in practical engineering projects with similar design procedure to cast-in-situ structures.

预制混凝土空心模剪力墙抗震性能试验研究

针对预制混凝土空心模具 (PCHM) 的剪力墙提出了一种新型剪力墙之间的连接方式。在这种方法中，在将混凝土倒入空心之前，将重叠的钢筋插入 PCHM。全尺寸试样在低循环载荷试验下进行测试，以分析其抗震性能，如破坏模式、滞后特性、刚度退化、能量耗散和延展性。对于预制试件，虽然在水平连接处出现贯穿裂纹，但没有大的滑移导致锚固失效和界面脱离。一般来说，与现浇剪力墙相比，PCHM剪力墙在承载力、破坏模式、刚度退化、能量耗散和延性等方面没有大的差异。所以，
