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。
Composite concrete-filled steel tubular columns have reasonable applications in fire resistance, reinforcement, and avoiding the use of thick steel plates. Based on the experimental study, this paper discusses the calculation method of the mechanical properties and bearing capacity of this composite steel tubular concrete column.
