BEHAVIOUR OF CONCRETE-FILLED SQUARE STIFFENED THIN-WALLED STEEL TUBULAR BEAM-COLUMNS
-
摘要: 采用通用有限元软件ABAQUS对带肋薄壁方钢管混凝土偏心受压构件的力学性能进行分析,并与试验结果进行比较,计算结果与试验结果吻合良好,表明所建立的有限元分析模型可较好地预测带肋薄壁方钢管混凝土的偏压力学性能。在此基础上,采用数值方法讨论了设肋与否对薄壁方钢管混凝土偏压构件力学性能的影响。Abstract: Behaviour of concrete-filled square stiffened thin-walled steel tubular columns under eccentric loading is investigated using ABAQUS software.The model prediction results are in good agreement with the test results.The effects of stiffening on the performance of thin-walled composite columns are then discussed.
