空间钢构架混凝土柱受力性能的有限元分析

Finite Element Analysis on the Behaviors of the Concrete Column with Spatial Steel Frame

基于ABAQUS有限元分析软件建立了空间钢构架混凝土柱受力性能的非线性分析模型,对空间钢构架混凝土柱受力性能进行了分析,将分析得到的荷载和位移曲线与试验所得的曲线进行比较,经检验两者基本吻合。在此基础上,分析了轴压比、配钢率等参数对空间钢构架混凝土柱受力性能的影响,得到了一些有益的建议可供工程应用时参考。

Based on the ABAQUS finite element analysis software, the nonlinear analysis model of the behaviors of the concrete column with spatial steel frame was established. An analysis of the concrete column with spatial steel frame specimens indicated that the load and displacement curve obtained by finite element analysis is consistent with those obtained by the experiment. The in-fluence of axial compression ratio, stirrup ratio and other parameters on the behaviors of the con-crete column with spatial steel frame were analysized. Some useful suggestions were obtained which may be a reference for engineering application.
