ABSTRACT
The aim of this study is to presents, testing and analysis result of stepped beams strengthened by carbon fiber-reinforced polymer, subjected to a point load at the center; eight beams have been used to investigate the flexural behavior of reinforced concrete beams which strengthened with carbon fiber reinforced polymer CFRP. The results showed that using of carbon fiber reinforced polymer CFRP it will provides additional strengthening flexural reinforcement, the reliability for this material application depends on how good they are bonded to concrete beam to transfer the stress from concrete to CFRP laminate.
