Abstract: External bonding of FRP on reinforced concrete elements is an interesting technique to repair or to strengthen them. In particularly CFRP show high strength, lightweight, resistance to chemicals and therefore these materials are not subjected to corrosion. This technique is experimented in a first study using CFRP sheets bonded to RC beams tested in four point bending. In particularly some tests are performed on precracked beams. It is observed that the effect of the strengthening on the behaviour of the beams depends on the precracking and on the number of layers of sheets. At ultimate stage the preloaded repaired beams can show better mechanical characteristics than the control beam. In all cases, a peeling-off failure is attended. In a second part numerical simulations are performed using a finite element code called Castem2000. This code was quite efficient to predict the behaviour of reinforced or repaired beams under four point bending. In particularly the use of interface elements allows the study of the stresses in the glue joint.
