Computer-based mathematical model for peformance prediction of corroded beams repaired with fiber reinforced polymers
In this paper a new mathematical model that predicts the load-deflection relationships of corroded RC beams repaired with FRP laminates is presented. The model accounts for the combined effects of corrosion, FRP strengthening, and FRP wrapping on the beam load-deflecting response. The beam is modeled as a series of elements, each having a length equal to the mean stabilized crack spacing. Then, for a given value of load the deflection of the beam is calculated by evaluating the elongation of the steel reinforcement within each element. The model was implemented into a computer program called ACFRP to examine its accuracy and reliability. A comparison of the model's predictions and the result of an experimental study carried out by the writers showed that the model accurately predicted the load-deflection relationships of corroded FRP repaired beams.
