Corrosion and Cracking of Reinforced Concrete

Modelling of the deterioration of reinforced concrete has in recent years changed from being a deterministic modelling based on experience to be stochastic modelling based on sound and consistent physical, chemical and mechanical principles.In this paper is presented a brief review of modern modelling of the reliability profiles for reinforced concrete structures. Deterministic models for different steps in the deterioration process are discussed. Several of the parameters used in the modelling are so uncertain that a stochastic modelling is natural. By crude Monte Carlo simulation predictions for time to initial corrosion, time to initial cracking, and time to a given crack width may be obtained
