装配式短肢剪力墙平面模型抗震性能试验

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

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.

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 co- efficients 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 mod- els, NPC models have similar carrying capacity, displacement ductility, energy dissipation capacity and high initial stiffness, and show similar seismic performance.
