This paper presents the results of an analytical and experimental study on the performance of repaired and strengthened rectangular Reinforced Concrete (RC) beams using epoxy injection and externally bonded Fibre Reinforced Polymer (EBR FRP) sheets. Five small-scale beams were tested under four-point bending in two phases. In Phase 1, three beams were tested up to the load level that induced cracking at service condition, whereas the other two beams were tested up to failure and used as control specimens. In Phase 2, one of the damaged beams was repaired using epoxy injection, subsequently strengthened using EBR FRP, and then tested again up to failure, whereas the other two specimens were only FRP-strengthened and tested up to failure. The test results indicate that the flexure capacity of a repaired and FRP-strengthened beam increased by up to 25% over the control beam, thus confirming that the strengthening solution was very effective at enhancing the flexural capacity of damaged RC beams. Moreover, the predictions given by linear cracked sectional analysis and the current ACI 440 guidelines match well the deflection response of the strengthened beams but only up to a service load.
