This paper presents a preliminary study on the durability of a bridge column under typical marine environments consisting of atmospheric, splash, and submerged conditions. To predict the migration of chlorides across the column, a simulation is conducted using a mathematical method, called cellular automata. Because chloride concentrations and the corrosion current density at the surface level of reinforcing steel can lead to the deterioration of a column over 100 years, they are of particular interest. The highest chloride concentrations are observed under the splash exposure, followed by the submerged and atmospheric conditions.
