Abstract: One of the most effective ways for improving the flexural strength of RC members consists in bonding FRP laminates at their soffit in order to upgrade the existing tensile strength. Strengthening RC beams by Externally Bonded FRP laminates is getting more and more common and various Codes of Standards have been issued in Europe, United States and Japan. In particular, the most up-to-date document has been released in Italy one year ago. A key problem to be faced when managing FRP strengthened beams deals with the possible premature failure due to debonding between the adhesive layer and concrete, which can occur at the beam end (end debonding) or in the cracked zone (intermediate debonding). In the present paper, a mechanical model considering non-linear stress-strain relationships for concrete, steel and FRP-to-concrete interface is presented, with the aim of simulating the behavior of RC beams strengthened by externally bonded FRP plates.
