摘要

钢管混凝土边框组合剪力墙是一种新型组合剪力墙。进行了2个1/4缩尺剪跨比为1.5的钢管混凝土边框组合中高剪力墙模型的低周反复荷载试验,模型1轴压比为0.35,模型2轴压比为0.65。在试验研究基础上,分析了轴压比对剪力墙承载力、延性、滞回特性、耗能能力的影响。建立了钢管混凝土边框组合中高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:钢管混凝土边框组合中高剪力墙抗震性能良好,具有重要的工程实用价值。
Composite shear wall with concrete filled steel tube columns is a new kind of composite shear wall.Experiment studies of the seismic behavior of two 1/4 scale models of composite mid-rise shear walls with concrete filled steel tube columns under low frequency circle load have been acccomplished,its shear span ration is 1.5.The axial-load ratio of the first model is 0.35 and that of the second model is 0.65.Based on the experiment,the effects of different axial-load ratios on the load-carrying capacity,the ductility,the hysteretic property,and the energy dissipation of the shear walls are analyzed.The formulas of the load-carrying capacity are established.The results obtained from the formulas and the experiment are in good agreement.The results show that the composite mid-rise shear wall with the concrete filled steel tube columns has good seismic performance and important applied value in engineering.
