Approche performantielle probabilisée pour la durabilité des bétons d'ouvrages en environnement marin

ABSTRACT The performance-type approach of durability is used for the study of an immersed concrete in sea water. The general and complementary durability indicators are exposed. To take into account the variability of those parameters, a probabilistic approach is proposed. Based on the concrete formulation and the chemical cement composition, the durability indicators are evaluated with the associated incertitude. The corrosion risk is estimated through the Lind-Hasofer reliability index. The application of this complete methodology has succeeded in validated the performance-type approach.
