Abstract
In this paper, the surface chloride content at the different positions in over 15-years old RC decks in open-piled piers with the various structural types and wave action were analyzed. The structural types were classified in terms of the existence or nonexistence of the curtain wall at the berthing side and the revetment behind the pier. Also, as the wave action, the wave from the open sea and the position of ship's arrival were considered. As the results, the value of surface chloride content was varied depending on the distance from the sea level. Furthermore, the value was influenced by the difference in structural types of RC decks and the wave action. From these results, the relation between the surface chloride content and the distance from the sea level, which can apply to the positions that not influenced by the structural types and the wave action, has been proposed. Moreover, the surface chloride content at the positions that influenced by the structural types and the wave action could be estimated by adding the proper amount of correction to the value calculated by the above proposed relation.
