Corrosion of reinforcement is the main deterioration mechanism of concrete structures. Al- though models for initiation phase of corrosion is well developed but there is little in the literature regarding analytical models for propagation phase, including cover crack width. Furthermore considering spatial vari- ability of deterioration has the advantage of estimation of probability and extent of deteriorated area which is a more valuable indicator in infrastructure maintenance planning and management. In this paper some mecha- nistic analytical models in literature has been reviewed and then using random fields the probability and ex- tent of failure of corrosion affected concrete structures under some serviceability limit state, e.g. critical crack width, is estimated. Finally expected life cycle costs of inspection and repair intervention is calculated with event based Monte Carlo method for various inspection intervals and acceptable extent of deterioration.
