A new mathematical model for predicting the inelastic flexural response of corroded reinforced concrete (RC) beams repaired with fiber reinforced polymer (FRP) laminates is presented. The model accounts for the effect of the change in the bond strength at the steel-to-concrete interface due to corrosion and/or FRP wrapping on the beam load–deflection response. The effects of FRP strengthening and the reduction in the steel reinforcement area due to corrosion on the beam strength are predicted by the model. A computer program was coded to carry out the modeling procedure and the model’s predictions were compared with the results of an experimental study undertaken to investigate the model’s reliability. A comparison of the predicted and the experimental results showed that the model accurately predicted the load–deflection relationships for corroded RC beams repaired with FRP laminates.
