方钢管混凝土柱的有限元模拟

Analyses of square concrete-filled steel tube column in finite element method

随着计算机科学的发展,有限元数值模拟方法应用越来越广泛,在此基础上,利用ANSYS程序对方钢管混凝土柱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,以便更好地了解钢管混凝土的力学性能。

With the development of computer science, the finite element method has been used widely. This paper uses ANSYS to study nonlinear response of square concrete-filled steel tube column under axial loading. Via analyses show effective stress-strain curve of concrete under axial loading. So as to better understand the mechanical functions of steel tube concrete.
