CFRP has been used mainly for strengthening of existing structures in civil engineering area. Prestressed strengthening is being\nstudied to solve the bond failure model featuring EBR and NSMR methods. The largest disadvantage of the prestressing system\nis that the system cannot be removed until the filler is cured. This problem lowers the turning rate of the equipment and makes\nit limited to experiment, which stresses the necessity of a new prestressing system. Therefore, the present study applies a new\nprestressing systemwhich reliefs the need to wait until the curing of the filler after jacking to the prestressing ofNSMR and examines\nthe effect of the prestressing size and location of the anchorage on the strengthened behaviour.The experimental results show that\nthe crack and yield loads increase with higher level of prestress, while the ductility tends to reduce, and the anchor plate should\nbe installed within the effective depth
