摘要:
为综合评价水平拼缝U型闭合筋连接的装配式混凝土剪力墙抗震性能,对其足尺试件进行了低周反复荷载试验并与现浇试件对比.试验结果表明:对于破坏形态,U型闭合筋连接试件与现浇试件基本相同;由于水平拼缝的存在,U型闭合筋连接试件的受力全过程的表现形式与现浇试件不相同;两者滞回曲线均较饱满,骨架曲线走势基本一致,耗能能力接近;两者极限位移角分别为1/46和1/49,位移延性系数均为4,满足延性要求;U型闭合筋试件较现浇试件初期刚度、开裂荷载有所降低,但峰值荷载承载能力提高.装配式混凝土剪力墙结构水平拼缝采用合理构造可以达到与现浇结构相当的承载能力、延性以及抗震耗能能力.
Abstract:
To comprehensively evaluate the seismic performance of precast concrete shear wall with U-shaped closed reinforcements connected in horizontal joints, a fabricated and a cast-in-place concrete shear wall with full scale specimens were tested and compared under low cyclic loading. The test results show that the failure pattern of the U-shaped closed reinforcements is basically the same as that of the cast-in-place specimen. The form of stress process of the U-shaped closed reinforcements is different from that of the cast-in-place test piece due to the horizontal joints. The hysteresis curves of both specimens are full, and the trends of the skeleton curves are basically the same; the capacities of the energy dissipation are also similar. The ultimate displacement angles of the two specimens are 1/46 and 1/49, respectively, and displacement ductility factors are 4, which meet the ductility requirements. The initial stiffness and cracking load of U-shaped closed reinforcements are lower than those of the cast-in-place specimen, but the peak load carrying capacity is increased. Precast concrete shear wall with reasonable horizontal joints can achieve similar carrying capacity, ductility and seismic energy dissipation capacity to the cast-in-place specimen.
