It is important that a citizen can continuously use infrastructures with reliability, safety and comfortableness. Based on the above background, the objective of this study is to design a system of a maintenance plan to concrete structure with chloride induced corrosion. That is, the priority of the inspection is determined and the system which performed a necessary reasonable countermeasure is investigated. Therefore the next methods were developed; 1) It is understood where the structure whose deterioration rate is fast. 2) It is understood where the area or part whose deterioration rate is fast. 3) The steel corrosion rate in the existing structure is quantitatively checked in easiness. 4) The structure is repaired depending on the requirement performance. Finally the system designed the maintenance plan was suggested under these cooperate.
