A reliable assessment of the performance reinforced concrete structures affected by reinforcement corrosion requires a through understanding both material deterioration and its impact on structural behaviour in order to evaluate safety serviceability, addition estimating remaining life.This paper presents an approach for service life prediction exposed chloride environments that combines finite element modeling transport reliability-based analytical model onset damage accumulation.Service is defined as time until accumulation reaches unacceptable level or 'limit state'.The used here models actual physical mechanism mechanical build-up with probabilistic methods obtain quantitative estimate deteriorating structures.The considerable uncertainties associated parameters govern buildup corrosion-induced are modeled random variables.By using Monte Carlo simulation, distributions penetration front initiation generated.The proposed illustrated bridge deck chlorides from de-icing salts.
