Descripción
Sumario: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 embedded CFRP strips or rods to the 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.
