    Description

    Experte en Mécanique des structures, et en résolution de problèmes couplés (sols, fluides, solides), après une expérience à EDF R&D, j'ai acquis une expérience notable en R&D Génie Civil pour les ouvrages spéciaux (enceintes nucléaires, barrages).

    Actuellement co-responsable du Management du Projet National CEOS.fr pour EDF SEPTEN qui se termine fin 2015 par l'édition d'un guide de recommandations de dimensionnement à usage des ouvrages spéciaux. Ces travaux permettent d'alimenter les propositions françaises d'évolution de l'Eurocode 2 et notamment de mieux appréhender les problèmes de gradients thermiques au sein des pièces épaisses. Les méthodes avancées d'auscultations et d'instrumentations ont été évaluées sur les corps d'épreuve, incluant l'analyse par corrélation d'images sur grands ouvrages.

    Cette expérience complète une première expertise en dimensionnement structures composites (céramique et organique) et collage (effets de bords), ainsi que des développements numériques de modèles de sol, notamment adaptés aux sols renforcés par inclusions rigides.
