Abstract
The strengthening of reinforced concrete structures with FRP materials has received a considerable increment in recent years due to the high strength-weight and stiffness-weight ratios of FRP compared to other materials. An experimental programme was conducted in order to analyse the behaviour of different structural solutions to strengthen reinforced concrete beams with FRP composites (EBR GFRP, EBR CFRP, NSRM-CFRP) and is described. The RC T beams had a 3m span by 0.3m height and were tested until rupture in a 4-point bending test system. The NSMR technique has proved to be the most effective of the three alternatives tested, as it obtained high strength, combined with high ductility. Nevertheless, all the systems show great strength increment in relation to the non retrofitted T-beams, proving to be effective approaches to the flexural strengthening of RC beams.
