| Résumé : |
This article aims to expose a probabilistic methodology for the design of concrete formulations in a marine environment. As defined in the performance-based approach, durability indicators, considered as random variables, will be defined by quantifying their variability. Based on elementary models for engineers, a classical probabilistic approach is then proposed: the probability to depassivate the reinforced bars, through a reliability index, is estimated in order to insure the durability of concrete. Moreover, a Bayesian network is used to update the distributions of random variables. |
