The load-carrying capacity of these CFRP EBR beams can be influenced by the strengthening of their ends, which controls the premature end failure occurring when the anchorage length of the plates or the shear span/depth ratio are low. Different basic techniques are proposed to prevent this brittle failure: use of clamps at the ends of the beam, bonding of lateral perpendicular or inclined strips and U-wrapping of shear spans with carbon fibre textile. The debonding mode of failure has systematically taken the place of the concrete cover separation mode. Lateral bonding of CFRP strips and U-wrapping using carbon fibre textile are particularly efficient for the control of debonding cracks and delay the premature end failure of the beams. The loadcarrying capacity is enhanced, and the ductility is increased.
