The present study examines the performance of rectangular simply supported
reinforced concrete (RC) beams with externally bonded reinforcement
(EBR) made of carbon fibre-reinforced polymer (CFRP) plates. 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.
