轴向力作用下方钢管混凝土柱的非线性分析

Nonlinear analyses of square concrete-filled steel tube column under axial loading

利用ANSYS程序对方钢管混凝土的受力性能进行非线性有限元数值分析,得出混凝土在轴向力作用下的等效应力应变曲线,对方钢管混凝土中内填混凝土的力学性能有了更好的了解。

This paper uses ANSYS to study nonlinear response of square concrete-filled steel tube column under axial loading. Via analyses shown effective stress-strain curve of concrete under axial loading. So we can know more about mechanical property of confined concrete.
