摘要

摘要: 为了解钢骨-钢管混凝土柱在低周往复荷载作用下的力学性能，对5根底层柱进行了低周反复荷载试验并对试验结果进行分析，得到不同含钢率和轴压比下的荷载-位移滞回曲线及骨架曲线，分析比较了轴压比和含钢率对构件承载力的影响。研究表明，钢骨-钢管混凝土柱滞回曲线图形饱满，表现出良好的耗能能力。由骨架曲线分析得知：随着含钢率的增加，构件承载力和延性有明显的提高；随着轴压比的增加其骨架曲线下降段越陡，相应的构件延性越差，轴压比越低则构件延性越好。

Abstract: To understand mechanical properties of circular steel tube composite columns filled with steel reinforced concrete under low frequency cyclic loading,five circular steel tube composite columns filled with steel reinforced concrete under horizontal low-cyclic loading are tested,whose results are analyzed.The looping curves and the skeleton curves under different axial compression ratios and different steel ratios are obtained,and it is compared the effects of different axial compression ratios and different steel ratios on bearing capacity of members.The results show that circular steel tube composite columns filled with steel reinforced concrete has a high bearing capacity,and a good capacity of energy dissipation.From the skeleton curve,it is found that with the increase of steel ratio,the bearing capacity and ductility of columns have been significantly improved;in addition,with increase in the axial compression ratio,ductility of the components is decreased and the lower the axial compression ratio,the better the ductility of the components.
