摘要
考虑到应用我国现行钢结构规范对折线形钢箱柱进考虑到应用我国现行钢结构规范对折线形钢箱柱进行设计时存在较大的不确定性,以长沙滨江文化园"两馆一厅"建筑群的核心建筑音乐厅为工程背景,利用ANSYS软件对影响折线形钢箱柱在常轴力、循环水平荷载作用下的滞回性能及影响因素进行数值建模分析。主要研究了壁板宽厚比和轴力值对滞回性能及其破坏模式的影响,对折线形钢箱柱的设计提供了有益的建议。
There is a great uncertainty in the design of folded line steel box column in the specification for structural steel in our country. In this paper, ANSYS software is used to analyse hysteretic behavior and factors when the folded line steel box column in the constant axial force and cyclic lateral loads by numerical modeling. Influence of the panel width-thickness ratio B/t and axial force value to the hysteretic behavior and failure mode are main studied. On the base of them, some suggestions about the design of folded line steel box column were proposed.
