摘要
用弹塑性大挠度有限元对不同腹杆布置形式的三肢钢管格构柱进行了稳定极限承载力研究,并与规范结果进行了比较,分析了腹杆布置形式及腹杆长细比对极限承载力的影响,为合理设计三肢钢管格构柱提供参考。
Ultimate load-carrying capacity study of three steel pipe latticed column is presented by employing an elastic-plastic large displacement finite element analysis, and the FEM analysis results are compared with steel codes results. The influence on ultimate load-carrying capacity of different belly pole layouts and slenderness ratio has been analyzed. Some proposes have been put forward for designing three steel pipe latticed column.
