1D and 2D analysis of chloride penetration into the reinforced-concrete pier, conducted in the cross-section of a Krk Bridge pier, and based on the finite-difference method, is presented in the paper. The time the chloride concentration next to reinforcement requires to reach the critical value is defined. In can be concluded, by comparison of results obtained in the analysis, that chloride penetration from two directions causes greater concentration of chloride next to reinforcement in the corner zone of structural elements, when compared to concentration anticipated by the 1D model, for the same period of analysis.
