内藏钢桁架混凝土组合中高剪力墙抗震性能试验研究
|
摘要
进行了3个1/3缩尺的中高剪力墙的抗震性能试验研究,包括1个混凝土中高剪力墙、1个内藏钢框架组合中高剪力墙和1个内藏钢桁架组合中高剪力墙。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中高剪力墙的抗震性能比普通混凝土中高剪力墙明显提高;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显著提高。
The experimental study on the seismic behavior of three 1/3 scale mid-rise shear walls,including a mid-rise shear wall with steel frame,a mid-rise shear wall with steel truss and a usual one,has been made.Based upon the experimental study,the stiffness and its attenuation,bearing capacity,ductility,hysteresis property and failure phenomena of each shear wall are contrastively analyzed.The experimental results show that the seismic behavior of the mid-rise shear wall with steel frame has been obviously improved and the seismic behavior of the mid-rise shear wall with steel truss has been observably improved compared with the usual one.
