Abstract: Chloride-induced reinforcement corrosion is one of the major causes to the deterioration of concrete structures, particularly in bridge deck. This paper has described a performance-based life cycle cost management (LCCM) model for reinforced concrete structures relative to corrosion deterioration. This model is characterized by three features: (1) a chloride-induced probabilistic corrosion deterioration mechanism is used to predict the service life of concrete structures; (2) the performance of a concrete structure is measured by serviceability limit states and structural capacity limit states; and (3) a dual management methodology is adopted, in which management actions are optimized to maximize the life cycle performance of a concrete structure under limited budget constraints and minimum required serviceability constraints. Case studies of bridge decks are provided to demonstrate the application of this performance-based LCCM model.
