External bonding of fibre reinforced plastic (FRP) strips to reinforced concrete (RC) beams has been widely accepted as an effective method for strengthening. The ultimate flexural strength of strengthened RC beams can be improved significantly, but it is often impaired by premature failure modes, such as concrete cover separation. Several models have been proposed dealing with this issue. The aim of this study is to assess the performance of the existing models with experimental data gathered from the published literature. Moreover, this work presents a study on the bond strength using...
