In the present work, experimental and numerical investigations were carried out to examine the flexural performance of reinforced concrete (RC) beams after undergoing different degrees of accelerated reinforcement corrosion and strengthened using ultrahigh-performance fiber reinforced concrete (UHPFC) layers. The strengthened RC beams were tested under flexure to evaluate the effect of the UHPFC layers (with combinations of three UHPFC layer thicknesses for both options of one-sided and threesided strengthening) on the failure mode, flexural strength, and stiffness. The flexural strength of the RC beams was significantly enhanced by increasing the thickness of the UHPFC layer. Three-sided strengthening resulted in a higher load-carrying capacity of the RC beams as compared to that of one-sided strengthening. Minimum layer thicknesses required to fully restore the load-carrying capacity of the corroded RC beams were found to be 20 mm and 40 mm for three-sided and one-sided strengthening, respectively. At ultimate load, the mid-span deflections for the strengthened beams were about half of that of the un-strengthened beams due to an increase in the stiffness of the strengthened beams. Finally, the experiment results matched the 3D-FEM predictions, indicating the simulation's accuracy in evaluating corroded-strengthened RC beam flexural performance.
