摘　　要：复式钢管混凝土柱在耐火、加固和避免采用厚钢板等方面有其合理的应用场合。本文在试验研究的基础上，探讨了这种复式钢管混凝土柱的力学性能和承载力计算方法。In the construction of steel tube - confined concrete columns, it is reasonable to usemultibarrel tubes for increasing of fire-resistance and strengthening of the existing columns toavoid the use of thick-wall tubes for heavily loaded columns. Based on experiments, themechanicaI behavior and the limit analysis of load bearing capacity of this kind of columns aredescribed.

关 键 词：钢式混凝土柱 极限分析 承载力
