Retrofitting is essential for extending the service life of aging reinforced concrete (RC) structures. Fibre Reinforced Polymer (FRP) wrapping has emerged as an efficient, lightweight, and cost-effective technique to enhance flexural and shear capacities of RC beams. This paper reviews key published studies on FRP retrofitting, focusing on flexural strengthening. A simplified analytical model is developed to estimate the increase in bending capacity when RC beams are retrofitted with externally bonded FRP sheets. Results show that wrapping with a single layer of carbon FRP (CFRP) can increase ultimate moment capacity by ~25–30%. The paper also discusses practical challenges and future research directions.
