Retrofitting reinforced concrete members by adhesively bonding fibre reinforced polymer plates to their surfaces is now a well established technique as there has been substantial and much good research on the numerous individual plate debonding mechanisms which has allowed safe designs. In this paper, it is shown how the apparently numerous and individual debonding mechanisms can be categorised into a few distinct generic debonding mechanisms, which should help to simplify the problem and consequently, in the long term, allow the development of generic design rules.
