| Abstract: | 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. |
