| 摘 要： | 轻骨料混凝土(L ight-we ight concrete,简称LC)剪力墙的轴压比是剪力墙抗震设计时一个重要的控制因素,直接关系到其延性性能。为使设计规程具有足够的理论依据,本文通过对六榀轻骨料混凝土剪力墙试件的试验,研究了在低周反复荷载作用下,着重考虑不同轴压比对中等高度有边框剪力墙的破坏形态和变形性能的影响效应,对其滞回特性进行分析,计算了各剪力墙的刚度退化率与延性系数,并将无竖缝剪力墙与带竖缝剪力墙的抗震性能进行了对比。

| Abstract: | The axial compression ratio has always been a vital element in light-weight concrete shear wall design relating to its own ductility.In this paper,based on the experiment,the failure mode and the seismic behavior of mid-rise light-weight concrete shear walls under cyclic loads,especially under different axial loads,are closely examined.By calculating the rigidity degradation ratio and the ductility ratio of each shear wall,a comparison is also made between shear walls with vertical joints and those without vertical joints. |
