[摘要]对4个装配式空心剪力墙试件进行拟静力试验,模拟了不同的轴压比和剪跨比对试件抗震性能的影响。通过低周往复加载试验得到试件的滞回曲线,并分析其延性、耗能性能和刚度特征。试验结果表明:装配式空心剪力墙的抗震性能和普通钢筋混凝土剪力墙抗震性能相似,且空心孔洞和水平拼接缝不会削弱墙体的受力性能,各个试件均表现出良好的延性和耗能能力,因此可以通过提高水平拼接缝的位置改善墙体抗震性能。[关键词]装配式空心剪力墙; 水平拼接缝; 抗震性能中图分类号:TU375 文献标识码:A 文章编号:1002-848X(2016)10-0032-05
Seismic performance research of prefabricated hollow shear wallZhang Guowei, Xiao Wei, Chen Boshan(Beijing Higher Institution Engineering Research Center of Civil Engineering Structure and Renewable Material, Beijing University of Civil Engineering andArchitecture, Beijing 100044, China)Abstract: Pseudo-static test was carried out on 4 specimens of prefabricated hollow shear wall (PHSW) to simulate effects of different axial compression ratios and height to width ratios on the seismic performance of PHSW specimens. The hysteretic curves of specimens were obtained by low cyclic loading test, and the ductility, energy dissipation and stiffness characteristics of the specimens were analyzed. Experimental results show that the seismic performance of prefabricated hollow shear wall is similar to that of common reinforced concrete shear wall, and hollow holes and horizontal joints will not weaken the mechanical performance of the wall. Each specimen exhibits good ductility and energy dissipation capacity, so the seismic performance of the wall can be improved by raising the horizontal joint′s position.Keywords: prefabricated hollow shear wall; horizontal joint; seismic performance
