Abstract: 
This paper presents an assessment of the flexural behaviour of sound, deteriorated and repaired Post-Tensioned (PT) beams of companion paper (Shekarchi et al. 2012) by three-dimensional nonlinear Finite Element (FE) analysis. The effects of stress relaxation of strands, exposing of the corroded reinforcement, and interface characteristics between repair concrete and substrate have been considered in the FE models. By comparing the model predictions and the experimental results, it was found that the model is capable of sufficiently good prediction of the structural response of investigated PT beams with bonded tendons.
