摘　　要：用弹塑性大挠度有限元对不同类型、不同腹杆布置形式的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,为合理设计钢管格构柱提供参考。Ultimate load-carrying capacity study of steel pipe latticed column is presented by employing an elastic-plastic large displacement finite element analysis,and the FEM analysis results are compared with those of steel codes.The influence on ultimate load-carrying capacity of different web member layouts and slenderness ratio has been analyzed.Some proposals have been put forward for designing steel pipe latticed column.

关 键 词：格构柱 极限承载力 有限元
