I NTRODUCTION

iber-reinforced polymer (FRP) materials are widely used in civil engineering for strengthening and retrofitting existing concrete structures. With ageing infrastructure and increasing exposure to environmental degradation, there is a growing need to enhance the durability, strength, and serviceability of structural systems. Strengthening becomes especially important in cases involving construction defects, changes in codal requirements, modifications in usage, or damage due to fire or accidental loads. Among various strengthening techniques, externally bonded reinforcement (EBR) using FRPs has gained prominence due to its ease of installation, high strength-to-weight ratio, minimal alteration to the existing geometry, corrosion resistance, and improved structural performance in terms of strength. A wide range of FRP F
