An experimental program was performed through this research to assess the flexural strengthening capacity of reinforced concrete beams strengthened using CFRP sheets with variable end anchorage systems to enhance the bond between the CFRP sheets and concrete. Four point bending tests were performed on five R.C. beams, a control beam without strengthening, two beams strengthened with one and three layers of CFRP and bonded using only epoxy, and two beams strengthened with three layers of CFRP sheets using two different end anchorage systems. The proposed end anchorage systems increased the load carrying capacity of the beams by around 14% compared to the conventional bonding with epoxy, and changed the failure mode from debonding of the sheets to rupture of the sheets. The bottom reinforcement and the CFRP sheets showed a close load - strain behaviour, which indicates perfect bonding between the concrete substrate and the FRP sheets.
