摘要
进行了3个1/3缩尺的高剪力墙的抗震性能试验研究,包括1个普通混凝土高剪力墙、1个内藏钢框架混凝土组合高剪力墙和1个内藏钢桁架混凝土组合高剪力墙。在试验研究基础上,对比分析了各剪力墙的刚度及其衰减过程、承载力、延性、滞回特性及破坏特征。试验表明:内藏钢框架混凝土组合高剪力墙的抗震性能比普通混凝土高剪力墙明显提高;内藏钢桁架混凝土组合高剪力墙的抗震性能比普通混凝土高剪力墙显著提高。
The experimental studies on the seismic behavior of three 1/3 scale high-rise shear walls, including a high-rise shear wall with steel frame, a high-rise shear wall with steel truss and a usual one, has been completed. Based upon the experimental studies, the stiffness and its attenuation, bearing capacity, ductility, hysteresis property and failure phenomena of the shear walls are analyzed and contrasted each other. The experimental results show that the seismic behavior of the high-rise shear walls with concealed steel frame has been obviously improved and the seismic behavior of the high-rise shear wall with concealed steel truss has been significantly increased in comparison with the usual one.
