中文摘要：

结合钢管约束型钢混凝土柱和纤维增强复合材料管约束型钢混凝土柱的优点，提出了复材一钢复合管约束型钢混凝土柱，其中复合管的内管为钢管，外管为复材管。进行了2个方形复材一钢复合管约束型钢混凝土柱试件和1个方形钢管约束型钢混凝土对比试件的滞回性能试验研究，3个试件的剪跨比均为4，试件的主要变化参数为外包玻纤布层数（6层和8层）。试验结果表明：方形复材一钢复合管约束型钢混凝土柱的抗剪承载能力、延性和耗能能力明显优于方形钢管约束型钢混凝土柱的，而且随着外包玻纤布层数的增加，复合管约束型钢混凝土柱的抗剪承载能力、延性和耗能能力逐渐提升；3个试件的破坏模式均为弯曲破坏。

英文摘要：

Combined with the advantages of steel tube confined steel reinforced concrete （STCSRC） column and fiber reinforced polymer （FRP） tube confined steel reinforced concrete （SRC） column, a FRP- steel composite tube confined SRC （FSTCSRC） column was proposed, where the FRP - steel composite tube was composed of inner steel tube and outer FRP tube. The seismic performance of square FSTCSRC column was studied by testing two square FSTCSRC columns and one square STCSRC column （control specimen） under combined axial constant compression and lateral cyclic load. The shear span to depth ratios of the three specimens was 4. The main test parameter was the layers of glass fiber fabric wrapping outside （6 layers and 8 layers）. The test results indicated that the shear strength, ductility, and energy dissipation ability of square FSTCSRC column were remarkably higher than those of square STCSRC column. The shear strength, ductility, and energy dissipation ability of square FSTCSRC columns increased as the increase in layers of glass fiber fabric wrapping. The failure mode of the three columns was flexural failure.
