摘　　要：通过对12个钢管混凝土长柱试件的试验分析,探讨了影响钢管混凝土长柱承载力的因素;引入切线模量概念,从理论上推导出钢管混凝土轴压长柱承载力的公式。By experimental research of twelve concretefilled steel tubes which have four kinds of lengthtodiameter ratio, we can get the influence factors of the bearing capacity of long concrete filled steel tubular columns. The tangential modulus and the conception of metal material are led to the limit bearing capacity formula of the concretefilled steel tube long column subjected to axial compression.
