Structural retrofitting is the process of modifying existing buildings or structures to improve their performance, safety, functionality, or sustainability. Near-Surface Mounting (NSM) is a retrofitting technique used to enhance the structural performance of concrete elements, particularly beams and slabs, by adding reinforcement near the surface of the concrete. The use of Near-Surface Mounted (NSM) Basalt Fibre Reinforced Polymer (BFRP) rods as a retrofit method for RC beams is investigated in this study. Because of its high tensile strength, resilience to environmental degradation, and longevity, BFRP materials are becoming more and more popular as an efficient and sustainable alternative for conventional reinforcement techniques. The flexural behaviour of RC beams retrofitted with NSM-BFRP rods is investigated using Finite Element Analysis (FEA) in Ansys. Key parameters such as stiffness, crack resistance, and load-carrying capacity are analysed to evaluate the improvements achieved through this method. Furthermore, the study covers both the advantages and disadvantages of employing NSM-BFRP rods, giving structural engineers a better understanding of its real-world uses.
