| Abstract: | On the basis of experimental investigations,different failure modes are given for RC beams strengthened with bonded pretensioned laminates of fiber-reinforced polymer(FRP) according to concrete strain at compression zone.The expressions are derived for calculating the ultimate strength in flexure and the predicted results are in good agreement with the measured values.Further the design procedure is put forward for enhancing flexural strength of RC members by externally bonding prestressed FRP Laminates. |
