摘　　要：为验证浆锚连接装配式剪力墙的抗震可靠性并确定其受力性能,对一浆锚连接装配式剪力墙空间结构模型进行了低周反复加载试验。试验过程中观测了浆锚连接装配式剪力墙以及叠合连梁的开裂规律和破坏特点,测得了空间结构模型的荷载、位移数据,并以此为基础,进一步分析了浆锚连接装配式剪力墙空间结构模型的关键抗震性能参数。试验研究发现:浆锚连接装配式剪力墙的首条裂缝出现在浆锚搭接区的端部,并受拼缝界面水平相对滑移的影响;浆锚连接件的连接性能可靠,最终破坏阶段未出现连接件的失效;装配式剪力墙具有较好的抗震性能,但是其连梁的力学性能过于薄弱,在连梁屈服后整体结构的耗能性能并未出现明显的提高。研究表明浆锚连接在搭接区的边缘存在两个新的薄弱面,建议在装配式剪力墙中应重视连梁的合理设计。To determine the seismic performance of grouted connected precast shear wall and verify its reliability,the low cycle reversed loading test was carried out on a spatial structure model with grouted connected precast shear wall.During the experiment,the crack distribution and developing principles of grouted connected precast shear wall and composite coupling beam were observed and the load and displacement data were collected;furthermore,based on the collected data,the key mechanical parameters of the spatial structure model were determined and analyzed. According to the test results,precast shear wall firstly cracks at the ends of the overlapping section,and the crack developing is affected by the slip of joint interface. The connection performance of grouted connectors is reliable and no grouted connector fails during the test. The mechanical performance of connecting beam is not sufficient,leading to the early yielding of its steel bars,and it contributes less to the energy consumption of the spatial model. Lastly,according to the experimental results,the existence of two new weak points at the overlapping section is justified and the connecting beam should be designed properly for precast shear wall structures.
