摘   要： 为研究圆多腔体中空钢管混凝土柱的抗震性能，首先对圆实心分腔复式钢管混凝土柱试件的试验结果与有限元结果进行比对，确定了有限元模拟方法有效后，再利用 ABAQUS 建立了以轴压比 ( 0. 2 ~ 0. 6) 、剪跨比  (3 ~ 5)、截面形式（ 圆多腔体中空截面与圆多腔体实心截面）为基本参数的 12 根柱模型，对其进行了低周往复加载，对比分析了剪跨比、轴压比、截面形式对模型滞回曲线、骨架曲线 、延性系数 、刚度退化以及耗能能力的影响规律 。结果表明： 剪跨比较小的模型，随轴压比的增大延性系数与耗能能力增幅明显，但轴压 比对刚度退化的影响不明显； 剪跨比较大的模型，在轴压比也较大时极限承载力、延性与耗能能力有显著衰减的趋势，刚度退化也对轴压比较为敏感； 在轴压比较小时，圆多腔体中空钢管混凝土柱与圆实心分腔复式钢管混凝土柱相比耗能能力差异不大，但随轴压比增大，圆多腔体中空钢管混凝土柱滞回耗能有显著提高。

Abstract: In order to study the torsional bearing capacity of circular multi-cavity hollow concrete filled steel tubular columns, the results of compression-torsional tests of four circular hollow concrete filled steel tubular specimens were compared with the results of finite element simulation analysis, after determining the rationality of the finite element simulation, the torsional bearing capacity of 24 column models with axial compression ratio and section form as basic parameters under uniaxial and reciprocating loading is analyzed. The results show that the concrete filled circular multi-cavity hollow steel tube model has stronger torsional bearing capacity than the concrete filled circular hollow steel tube model When the axial compression ratio≤0.4, the model of circular four-cavity hollow sandwich concrete filled steel tube columns under uniaxial loading has remarkable torsion resistance, concrete filled hollow steel tubular columns with circular six cavities have good torsional capacity and ductility under axial compression ratio of 0 ~ 0.6 ,the torsional bearing capacity of the circular multi-cavity hollow concrete filled steel tube column model under reciprocating loading is larger than that of the circular hollow concrete filled steel tube model.
