The performance of conventionally reinforced concrete beams strengthened with externally bonded fibre reinforced plastics (FRP) was studied by compiling and analyzing an experimental database. A total of 64 specimens from 10 separate studies were included in the database. A profile of specimens in the database is given, followed by an analysis of trends in failure mode, strength gain and deformability. Failure by debonding of FRP was prevalent among specimens in the database. One-third of the specimens with external reinforcement added showed strength increases of 50% or more in combination with considerable deflection capacity. Recommendations for future studies are given.
