The use of fibre reinforced polymers (FRPs) as rebars in reinforced concrete (RC) elements is a viable means to prevent corrosion
effects that reduce the service life of members employing steel reinforcement. However, durability of FRP rebars is not straightforward
as it is related to material properties as well as bar–concrete interaction. A state of the art of durability of FRP rebars is presented herein
in order to highlight issues related to the material properties and interaction mechanisms which influence the service life of RC elements.
The design approach implemented in international codes is discussed and the reduction factors taking into account the durability
performances are summarized.
