| 摘 要： | 轴压比是影响剪力墙抗震性能的一个主要因素,直接决定其延性性能。本文对两组共六个高剪力墙1/3缩尺的试件模型进行了不同轴压比下的低周反复荷载试验,研究了轴压比对内藏钢桁架混凝土组合剪力墙抗震性能的影响,对比了各试件的承载力、刚度及其退化过程、延性、滞回特性及破坏特征。试验表明:随着轴压比的提高其试件的承载力提高但延性下降;不同轴压比下内藏钢桁架混凝土组合剪力墙均能明显提高钢筋混凝土剪力墙的抗震性能。

| Abstract: | Axial-load ratio is a vital element affecting the seismic behavior of the shear wall and deciding its ductility.Based upon the experimental study on the seismic behavior of two kinds(six together) of 1/3 scale high-rise shear walls in different axial-load ratios under cyclic loads,the effects of different types of axial-loads on the seismic behavior of shear walls with concealed steel truss are researched and the bearing capacity,stiffness and its degradation,hysteretic property,ductility and failure phenomena of each shear wall are compared.The experimental results show that the bearing capacity of the shear wall is improved obviously while the ductility is reduced.At the same time for different axial-loads the RC shear wall with concealed steel truss can improve the seismic behavior of the shear wall. |
