摘　　要：进行了碳纤维布加固高轴压比混凝土柱在轴力及反复水平荷载作用下的试验。研究表明,碳纤维布提供了有效约束,试件延性明显提高。在试验研究的基础上,提出了碳纤维布改善高轴压比混凝土柱延性的设计建议。The responses of one RC column and five RC columns strengthened by CFS subjected to the axial compression and cyclic loading regime are investigated experimentally. Experimental results indicate that while RC columns are confined by CFS effectively, and their ductility can be evidently increased. Based on the experiment, the design recommendations are proposed.
