Etude du comportement mécanique de liaison BA Voile-dalle renforcé par PRFC sous chargement cyclique alterné

Abstract

L’utilisation des polymères renforcés de fibre de carbone dans la réparation est une technique largement rependue. On retrouve dans la littérature de nombreuses études ayant démontrées l’intérêt des renforts par PRFC dans le renforcement de structure face aux sollicitations sismiques. Cette étude cherche à étudier l’impact d’un renfort sur le comportement d’une liaison voile/dalle en béton armé. L’étude s’articule autour d’une campagne expérimentale menée sur 4 spécimens renforcés. L’objectif est d’étudier le comportement et l’endommagement de divers spécimens face à un chargement cyclique alterné. Le comportement des différentes configurations de renfort est comparé à celui de l’essai témoin. Les résultats montrent un gain de résistance pouvant atteindre 70% et de raideur de l’ordre de 60%. Les configurations de renfort n’ont que peu d’impact sur la ductilité des liaisons. Les tests montrent également que les solutions de liaisons renforcées ne dissipent pas plus d’énergie que le témoin.
