摘　　要：通过横向包裹碳纤维布的钢筋混凝土短柱在低周反复荷载作用下受力性能的试验研究，验证了碳 纤维布对钢筋混凝土短柱延性的改善作用。经碳纤维布包裹的钢筋混凝土短柱，其延性得到了显著改 善，但承载能力却变化不大。试验还发现，碳纤维布在使用中存在一个作用效率的问题，碳纤维布包裹 层数愈多，其作用效率愈低．Based on the experiments of four reinforced concrete short columns under cyclic loading, the effectiveness of the new method of using continuous carbon fiber sheet(CFS) on strengthening the reinforced concrete short columns for increasing their ductility is studied. Through the test data analysis, it is found that the ductility of the reinforced concrete short columns is significantly improved. And the reason, why the ductility of the hybrid columns is improved, is also analyzed.
