摘要
为了综合比较两种成孔方式下约束浆锚搭接方式的预制剪力墙的抗震性能,进行了2个预埋波纹管成孔和1个抽芯成孔的约束浆锚搭接连接方式的低周反复荷载试验。试验结果表明:两种成孔方式的约束浆锚搭接破坏形态基本相同,各滞回曲线饱满。骨架曲线也基本一致,延性系数均大于4。当两个墙体同时采用波纹管连接时,减小钢筋的搭接长度,抗震性能略微有所下降但仍然满足现行抗震规范的要求。
To comprehensively evaluate the seismic performance of precast concrete shear wall connected by two ways of hole,two concrete shear walls holed by prefabricated corrugated pipe and one concrete shear wall holed by drawing out the pipe were tested under low cyclic loading.The test results show that the wall holed by prefabricated corrugated pipe is basically the same as the wall holed by drawing out the pipe in failure modes.The hysteresis curves of the specimens are full,the trend of the skeleton curve is basically the same and the capacity of the energy dissipation is close.The displacement ductility factors are more than 4.For the two walls holed by prefabricated corrugated pipe,when the lap length is reduced,the seismic performance decline as well,but the wall still meets the current seismic code requirements.
