Aggressive marine environments and tidal conditions due to chloride ions attack and subsequent wetting and drying concrete, lead to excessive corrosion of reinforcing steel that creates destruction. Simulating behavior of corrosion can be effective in reducing the damage, regional investigations are necessary for durability-based design and evaluation of the models proposed for service-life prediction. In this paper Monte Carlo simulation use for service-life prediction of reinforced concrete structures in tidal zone. This study evaluates the influence of mean and standard deviation variations for each of the parameters that affect on the time of corrosion initiation. In tidal condition that studied in this paper, in the case of 10 mm convection depth with respect to non tidal zone, the service life of the structures decrease about 15 years. So it is found the effect of corrosion occurrence to standard deviation of concrete cover that must be noticed in constructions of marine structures.
