钢管自密实混凝土在工程结构中得到了广泛的应用.通过理论分析,建立了轴心受压钢管自密实混凝土短柱的承载力计算公式.并借助有限元分析软件ANSYS,考虑了钢管与混凝土两种材料本构关系的非线性,对轴心受压钢管自密实混凝土短柱进行了大量的非线性有限元分析,建立了钢管自密实混凝土短柱在轴心压力作用下的非线性有限元计算模型.通过数值模拟,对提出的轴心受压钢管自密实混凝土短柱的承载力计算公式得出的结果进行了验证,发现计算结果与有限元分析结果吻合良好.

The self-compacting concrete filled steel tubes are used widely in engineering structures.The computational formulas of bearing ca-pacity for self-compacting concrete filled steel tubular stub columns under axial compression are established by theoretical analysis.Taking into ac-count nonlinear constitutive relation of steel tube and concrete, the nonlinear finite element models for self-compacting concrete filled steel tubular stub columns under axial compression are established by a large number of nonlinear finite element analysis with finite element software ANSYS.The results obtained from the computational formulas are confirmed by numerical simulation,which shows that the computational result is in compliance with the result by ANSYS.
