Abstract

In recent literature, several approaches have been proposed for the sectional response of corroded rein-forced concrete structures. However, the lack of knowledge on corroded prestressed concrete (PC) members is still present. The present work focuses on the probabilistic assessment of the sectional response of a PC member by considering the influence of chloride-induced corrosion. First, the proba-bility distributions of the mechanical properties and the maximum pit depth are established. Second, the SCPS-model is then adopted to derive the residual stress-strain relations of corroded strands. Third, the effect of the random nature of the mechanical properties is investigated via Monte-Carlo simula-tions. Finally, the main outcomes enable to: (i) quantify the expected failure mode in a probabilistic way, and (ii) assess the influence of the selected random variables on the moment-curvature response.
