摘    要:为研究钢管混凝土边框剪力墙抗震性能,对不同轴压比、不同强弱抗剪连接键的矩形钢管混凝土边框剪力墙进行了低周反复荷载下的抗震性能试验研究.试验模型包括1个普通钢筋混凝土剪力墙和3个矩形钢管混凝土边框剪力墙,模型按1/4缩尺.在试验基础上,分析了各剪力墙的承载力、延性、刚度及其衰减过程、滞回特性、耗能能力和破坏特征.建立了该新型剪力墙的承载力计算模型,计算结果与实测结果符合较好.研究表明:这种剪力墙可有效地组合混凝土剪力墙与钢管混凝土边框柱的优势,抗震效果良好.

关 键 词:钢管混凝土  剪力墙  抗震性能  承载力

Abstract:Shear wall with concrete filled steel tube columns has being used in engineering in our country,but seismic experiment to it is rare in home and abroad.For studying its seismic performance,Seismic behaviors experiment research on shear walls with rectangular concrete filled steel tube columns under cyclic loading action have been done,in this paper,considering different axial-load ratio,strong and weak shear constructional measures.1/4 scaled experimental models are one traditional steel reinforced concrete shear wall and three these new kind of walls.Based on the experiment,load-carrying capacity,ductility,stiffness and its degradation,hysteretic property,energy dissipation and failure phenomena of each shear wall are analyzed. Load-carrying capacity mechanical model is established.The results obtained from the calculation are in good agreement with those from the experiment.The results show that this kind of shear wall can efficiently take advantage of concrete shear wall and concrete filled steel tube columns and has excellent seismic behaviors.
Keywords:concrete filled steel tube  shear wall  seismic behavior  load-carrying capacity
