Simplified models for the engineering of concrete formulations in a marine environment through a probabilistic method

摘要: This article aims to expose a probabilistic methodology for the design of concrete formulations in marine environment. As defined performance-based approach, durability indicators, considered as random variables, will be by quantifying their variability. Based on elementary models engineers, classical approach is then proposed: probability depassivate reinforced bars, through reliability index, estimated order insure concrete. Moreover, Bayesian network used update distributions variables. Cet une approche probabiliste pour l’elaboration de beton en environnement marin. Similairement l’approche performantielle, des temoins durabilite, consideres comme variables aleatoires, sont caracterises par leur variabilite. Sur la base modeles simples, classique est proposee: probabilite depassivation aciers passifs, au travers d’un indice...
