The new version of Eurocode 2 will include for the first time an informative annex, Annex R “Embedded FRP reinforcement”, to design reinforced concrete structures with fibre reinforced polymer (FRP) reinforcement.
FRP embedded reinforcement has some advantages such as their low susceptibility to corrosion, high-strength, and low life-cycle cost. FRP rebars can be used as longitudinal or transverse reinforcement in a similar way than conventional steel rebars.
However, in the design of FRP reinforced concrete structures, some particular aspects related to the reinforcement properties must be taken into account, among which it is worth highlighting their linear elastic behaviour until failure, their relatively low modulus of elasticity or their behaviour under sustained stresses. Since, the content of Annex R is new, a summary and background related to all aspects required for designing with FRP reinforcement are given in this paper.
