The purpose of this study was to introduce a proposed method to retrofit RC beams. This paper consists of study of the RC beam behavior after using Nano Silica, Carbon Fibre Reinforced Polymer (CFRP), Glass Fibre Reinforced Polymer (GFRP) and epoxy in order to attain maximum strength, so as to withstand the shear forces, bending moments and other related structural response parameters efficiently. For this purpose, casting of three sets of reinforced concrete (RC) beam. Failure modes of each of the beams were obtained. The change in load carrying capacity and failure mode of the beams were investigated. The laboratory experiment and numerical simulation were used to investigate the behavior of the beams. Three RC beams for three different condition such 10mm U shape Nano silica retrofitting, RC beam with CFRP external wrapping retrofitting and without retrofitting specimens were investigated.
