摘要

为研究轴心受压方钢管混凝土短柱钢管的力学性能,利用通用有限元分析软件ANSYS建立了方钢管混凝土柱的有限元模型,考虑了混凝土强度、截面宽厚比以及钢材强度对方钢管混凝土柱钢管纵向应力—应变关系的影响,为纤维模型数值分析提供了钢管的等效单轴应力—应变关系曲线的简化计算方法。
In order to study the mechanical properties of square concrete-filled steel tubular short columns subjected to axial compression,the finite element analysis software ANSYS was used to establish the finite element models and the effects of different parameters such as strength of concrete and steel,width-wall thickness ratio(aspect ratio)were considered,equivalent axial stress-strain relationship curve of steel tube for fiber-based model numerical analysis was put forward.
