Experimental Research on Reinforcing Damaged Reinforced Concrete Beams with Carbon Fiber Reinforced Plastics |
| |
Abstract: | Through shear tests of four damaged rectangular cross-section beams with simple supports, the strength of the inclined section of the beams reinforced with carbon fiber reinforced plastics(CFRP)is studied experimentally. The experimental results show that the effect of CFRP on beams' strengths is farourable. |

Keywords: | CFRP shear strength reinforcement deflection |
