| 摘 要： | 为了研究内藏钢桁架组合中高剪力墙的抗震性能,进行了6个1/3缩尺的中高剪力墙低周反复荷载试验,其中包括2个普通混凝土剪力墙、2个内藏钢框架混凝土剪力墙和2个内藏钢桁架混凝土剪力墙,轴压比分别是0.2、0.5。在试验研究基础上,对比分析了两种轴压比下各剪力墙的承载力、刚度、延性、滞回特性、耗能能力及破坏特征。试验及分析表明:在不同轴压比下,内藏钢桁架混凝土组合中高剪力墙的抗震性能比普通混凝土中高剪力墙的抗震性能显著提高;高轴压比下各剪力墙的承载力比低轴压比下相应剪力墙的承载力明显提高,但其延性及耗能能力降低。

| Abstract: | In order to investigate the aseismic performance of mid-rise RC composite shear walls with concealed steel truss,the low-frequency quasi-static cyclic loading experiments on six 1/3 scale mid-rise shear walls,including two usual shear walls,two shear walls with concealed steel frame and two shear walls with concealed steel truss,were carried out.The shear wall specimens were given an axial compression ratio of 0.2 or 0.5.Based upon the experimental study,load-carrying capacity,the stiffness,ductility,hyster... |
