Summary
Corrosion of reinforcing bars in concrete presents a global problem for safety, serviceability, and economic and environmental sustainability. Owing to the interrelation between transport of corrosives and cracking, predicting the onset and consequences of corrosion of steel reinforcement is challenging. Multiscale models of hydration, transport of water and chlorides, cracking, and material degradation can be used to improve predictions of structural capacity and remaining service life. Implementation of such models within a probabilistic framework that allows incorporation of uncertainty as well as analysis of corrosion-related outcomes of interest to owners is being studied. The performance-based durability engineering (PBDE) framework presented here combines flexibility in modeling with industry-oriented decision-making information.
