【摘要】 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。更多还原

【Abstract】 Hooping effect of steel tube in concrete filled steel tubular members is considered,then the accurate stressstrain relationship of concrete and steel tube is chosen to simulate the test results by nonlinear finite element analysis.At last the bearing capacity of members under axial compression is contrasted among different construction processes.更多还原
