【摘要】 为了了解内藏桁架钢管混凝土边框剪力墙抗震性能,进行了3个模型试件的低周反复荷载下的抗震性能试验研究.模型按1/5缩尺,包括1个普通钢筋混凝土剪力墙、1个矩形钢管混凝土边框剪力墙和1个内藏桁架矩形钢管混凝土边框剪力墙.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.研究结果表明,这种剪力墙抗震性能良好.更多还原

【Abstract】 In order to know the seismic behavior of the shear wall with concrete filled steel tube columns and concealed bracing,seismic behavior experiment research on three shear wall models under cyclic loading action have been done in this paper.1/5 of the scaled experimental model is used to make one traditional steel reinforced concrete shear wall,one shear wall with rectangular concrete filled steel tube columns and one shear wall with rectangular concrete filled steel tube columns and concealed bracing.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.A 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 has excellent seismic behavior.更多还原
