大量大跨桥梁、超高层建筑以及大型深海工程不断兴建，其中的承重柱承受极大的荷载，单纯依靠钢筋混凝土已经不能满足承载力和使用功能的要求，钢管-混凝土组合柱因其具有承载力高、塑性和韧性好、节约材料、方便施工等优点得到了广泛的应用。钢管-混凝土组合柱主要包括钢管混凝土柱、钢管混凝土叠合柱、钢管约束混凝土柱，对这三种钢管-混凝土组合柱从静力性能、抗震性能以及耐火性能等多方面的研究进展进行了系统总结和阐述。最后指出组合柱在复杂受力状态下的研究盲点，以及将再生混凝土和超高强混凝土应用于组合柱的发展前景，进一步推动组合结构的发展。

With the construction of many long-span bridge ,super high-rise buildings and large-scale deep sea engineering projects ,in which the load-bearing pillars are under tremendous stress ,the strength and serviceability of reinforced con-crete columns alone cannot meet the contemporary demands .Steel tube-concrete columns have been widely used in those structures mentioned above ,due to their high loading capacity ,plasticity and ductility ,low cost and the convenience of construction .The steel tube-concrete columns mainly include concrete-filled steel tube columns (CFST ) ,concrete-filled steel tube reinforced concrete columns (CFSTRC ) and steel tube confined concrete columns (STC ) ,the research progress of which were systematically summarized and explained from aspects of static behavior ,seismic behavior and fire resis-tance .At last ,this paper pointed out the blind spot in the study of complicated loading states ,and the prospect of apply-ing recycled aggregrate concrete and ultra-high strength concrete in steel tube-concrete columns ,in order to further pro-mote the development of composite structures .
