摘　　要：为了研究钢管高强混凝土组合柱的轴压性能,利用几个已有组合柱的试验数据,对ABAQUS软件的参数进行标定,完成了数值模拟与参数分析。分析结果表明,所选参数能够较好地模拟钢管高强混凝土组合柱的轴向受力性能。文中给出了箍筋间距、钢管套箍指标、含钢率以及管内混凝土强度4个参数对组合柱轴压性能的影响,以供设计参考。To study the axial compression performance of high strength concrete-filled steel tube composite columns,the test data of several concrete-filled steel tube composite columns are calibrated using the finite element software ABAQUS for numerical simulations with parametric analysis.The results show that the selected parameters can effectively simulate the axial compression performance of high strength concrete-filled steel tube composite columns.The influences of stirrup spacing,confinement index,steel ratio and concrete strength on the axial compression performance of composite column are given for the design reference.
