摘　　要：因为异形柱经常承受偏心受压加受扭的复杂受力,所以理论计算比较复杂。本研究使用有限元分析软件ABAQUS对T形截面型钢混凝土柱的抗扭性能进行了数值模拟分析,并考虑混凝土塑性发展探讨不同轴压比与钢骨率对型钢混凝土T形截面柱延性与抗扭承载力的影响。利用已有的实验数据,建立构件的受压有限元模型,通过对比荷载-位移曲线验证有限元材料本构的有效性。建立三组模型分析不同轴压比与钢骨率对构件抗扭力学性能的影响,为今后型钢混凝土异形柱的应用提供参考。In the case of the existence of eccentric compression of the special-shaped column and the complex force of the situation,the theoretical calculation is more complex.ABAQUS software are conducted to analyze anti-torsion of T-shaped steel reinforced concrete columns.Above all,in order to test the verification of the analytical model,finite element modals of test specimens are established to simulate the test process.By comparing the analytical results with experimental ones,it is turn out that the results from finite element analysis coincide well with the experimental test.Therefore ABAQUS software could be used as a supplementary tools to simulate SRC column mechanical behavior.Further the ductility and ultimate of anti-torsion capacity of T-shaped SRC columns are researched with the changes of steel ratios and the axial force ratio.
