Abstract
Deterioration of concrete structures has been drawing a greater social attention. Severe chloride-induced damages have been observed in seaside area. The deterioration is mainly caused by corrosion of reinforcements due to the action of chloride ion. This paper develops a procedure to determine design concrete cover for a deterioration due to chloride attack. Statistic method to seek design concrete cover is developed by using the stochastic parameters that contributes to structural damages. These stochastic parameters are obtained from data analysis conducted on the survey of actual structures and laboratory tests. This analysis is useful for durability design and rehabilitation planning during its service life.
