摘　　要：本文通过８根钢筋混凝土柱在周期反复荷载作用下受力性能的试验研究，验证了使用碳纤维布 包裹钢筋混凝土柱来提高其延性这种补强加固方法的有效性。本文分析了轴压比、混凝上强度、碳 纤维布强度以及碳纤维布的包裹范围、包裹层数等因素对抗震加固效果的影响。最后，还对碳纤维 布加固钢筋混凝土柱使其延性提高的机理进行了分析。Based on the experiment of eight reinforced concrete columns under cyclic loading, the effectiveness of the new method of using the continuous carbon fiber sheet (CFS) for strengthening the reinforced concrete columns and increasing their ductilities is examined. The factors such as axial compression ratio, concrete strength grade, the number of CFS layers, tensile strength of CFS and wrapping area are analyzed. And the reason, why the ductility of rein- forced concrete columns using CFS is improved, is also analyzed.
