In this study, the behaviors of damaged reinforced concrete beams repaired with fiber reinforced polymers (FRP) were investigated. Three reinforced concrete beams with deficient shear reinforcement were manufactured from same concrete mixture. Beams with similar geometrical properties and reinforcement details were tested under reversed-cycling loading. Moderate damage was applied to the beams. Then, beams were repaired using different FRP strips (CFRP and BFRP) with same arrangements. The failure modes, ultimate loads, ultimate displacements, curvatures, ductility and energy consumptions properties of beams were investigated. The cumulative energy consumption was increased 449% by repairing the moderately damaged reinforced concrete beam test element with CFRP and 140% by repairing it with BFRP. The failure mode of test specimen of repaired with BFRP did not change, but in repaired with CFRP, the failure mode of the test element was changed and the test element collapsed due to bending.
