装配式短肢剪力墙平面模型抗震性能试验

为促进建筑工业化和住宅产业化，进行了预制装配式短肢剪力墙平面模型的抗震性能试验研究. 对2个预制装配式和1个现浇的1/2比例单跨三层平面模型进行了低周反复荷载试验. 通过观察这两类模型的裂缝开展、破坏过程及破坏形态，对比分析两类模型的滞回曲线、骨架曲线、位移延性系数及耗能能力等，从强度、刚度、延性和耗能等方面综合评价了其抗震性能. 试验结果表明:与现浇模型相比，预制装配式模型具有相近的承载能力、位移延性及耗能能力，初始刚度较大，具有相当的抗震性能.

Test research on seismic performance of plane model of new precast concrete short-limbed shear wall

To promote building and housing industrialization,test research was carried out on the plane model of new precast concrete short-limbed shear wall(NPC).Low-cyclic reversed load test was carried out on two NPC and one cast-in-situ 1/2 scale plane models of three story and single span.By observing their failure processes and failure modes and contrasting their hysteretic curves,skeleton curves,displacement ductility coefficients and energy dissipation capacity,the seismic behavior was synthetically evaluated on aspects of strength,stiffness,ductility and energy dissipation.The test result shows that,compared to cast-in-situ models,NPC models have similar carrying capacity,displacement ductility,energy dissipation capacity and high initial stiffness,and show similar seismic performance.
