摘要：
This paper compares the flexural bearing capacity, rigidity, and ductility of the reinforced RC beams after comparative tests of reinforcing RC beams by three different ways: directly bonding CFRP, bonding CFRP after replacing concrete and bonding CFRP after replacing concrete and planting bar. The results show that the method of replacing concrete can sufficiently avoid the debonding between CFRP and concrete, improve the flexural bearing capacity, and further strengthen the rigidity and ductility; whereas the method of planting bar can well guarantee the bond of Young and old concretes, let the replacing concrete together with CFRP work better, and carry capacity increase in reinforcement.
