Abstract: This paper investigates the use of Near Surface Mounted Fibre Reinforced Polymers (NSM FRP) to strengthen reinforced concrete (RC) beams. Three RC beams were tested in flexure with different configurations: one control, one strengthened with one NSM FRP bar at the soffit, and one strengthened with two NSM FRP bars on the beam sides. This paper discusses the main experimental results. It is shown that results predicted by existing analytical models match well the test results, thus confirming the effectiveness of adding bars to the sides of the beams as a potential strengthening solution.
