考虑了钢管混凝土构件中钢管的套箍作用,通过合理选择钢管和混凝土材料的本构关系,利用非线性有限元分析来模拟试验结果。最后着重对比了不同施工加载过程对钢管混凝土水平构件轴压性能的影响。
Considering the hoop function of steel tube in concrete-filled steel tubular members, the nonlinear finite element analysis is used to simulate the test results by reasonably choosing the constitutive relation between steel tube and concrete material. Finally, the influence of different loading processes on the axial compressive properties of CFST horizontal members is emphatically compared.
