摘要
考虑初始缺陷的影响,采用通用有限元软件ABAQUS对薄壁方钢管混凝土轴心受压构件的力学性能进行分析,并将计算结果与试验结果进行比较,结果表示二者基本吻合。在此基础上,对不同参数条件下初始缺陷对薄壁方钢管混凝土轴心受压构件力学性能的影响进行分析。
By considering the effect of initial imperfection, ABAQUS software is used to perform nonlinear finite element analysis of behaviour of square concrete-filled thin-walled steel tubes under axial compression. The calculated loaddeformation curves are in good agreement with those of tests. The effects of imperfection under different conditions on the behaviour of thin-walled composite columns are analyzed.
