摘　　要：以ABAQUS为平台,基于混凝土损伤塑性模型和Von Mises屈服准则,合理划分网格,建立了圆钢管混凝土中长柱的有限元模型,以14根钢管混凝土中长柱试验试件为模型对象,将有限元模拟结果与试验结果对比,二者吻合性较好,误差在5%左右,表明采用非线性模型对钢管混凝土柱进行的计算分析较为准确,验证了有限元模型的正确性。In this paper,based on ABAQUS platform,and concrete damage plasticity model based on Von Mises yield criterion,a reasonable division of the grid,a finite element model of CFST column,to test 14 CFST columns for the model object,the FEM calculation results and the test data comparison,the simulation results agree well with the the test results show that,with an error of about 5%,by calculation and analysis of CFST column nonlinear model is more accurate,to verify the correctness of the finite element model.
