Strengthening of Existing Concrete Structures with Fibre Reinforced Polymers (FRP) in the New Version of Eurocode 2

Abstract

This paper aims to introduce the content of Annex J “Strengthening of Existing Concrete Structures with CFRP” of Eurocode 2 [1]. This is first time that the design of adhesively bonded reinforcement with CFRP has been introduced in the European regulations through an informative annex. Annex J considers two different bonded strengthening techniques: externally bonded reinforcement (EBR) that consists of bonding CFRP strips or sheets to the surface of concrete elements, and near surface mounted reinforcement (NSM) that consists of embedding a CFRP strip or rod to a slot cut in the concrete cover. Since, the content of Annex J is new, a
summary and background related to all aspects required for designing CFRP strengthened systems for concrete structures, are given in this paper.
