摘　　要：利用有限元分析软件ABAQUS对SRC-RC转换柱的受力性能进行了非线性数值分析,通过与试验结果对比,验证了数值分析结果的合理性。然后对配钢率和轴压比等参数进行了研究,结果表明,轴压比对构件承载力和滞回性能的影响较大,而配钢率的影响较小。Nonlinear numerical analysis of the stress performance of SRC - RC transfer columns was carried out in this paper with the finite element software of ABAQUS. Compared with experimental results, numerical analysis results are found to be reasonable. Then the influence of factors such as shaped steel ratio and axial-load ratio were contrastively analyzed. The results show that axialload ratio has a greater influence on the bearing capacity and hysteretic performance of the component, but the shaped steel ratio has less influence.
