Abstract

This study explored the behavior of reinforced concrete (RC) beams when reinforced with Basalt Fiber Reinforced Polymers (BFRP) bars using the Near-Surface-Mounted (NSM) technique. BFRP is a recently developed material known for its cost-effectiveness, high strength, and exceptional corrosion resistance, making it an attractive option for reinforcing and repairing RC structures. The experiment involved four RC beams, with one serving as a reference and three strengthened with BFRP bars via NSM. These beams underwent a four-point bending test to evaluate their performance. The research focused on two critical parameters: the BFRP reinforcement ratio and the embedment length, analyzing their effects on load-carrying capacity, mid-span deflection, crack patterns, and final failure modes of the beams. The results shed light on the influence of these parameters on the behavior and strength of the beams, providing valuable insights for optimizing BFRP reinforcement strategies in enhancing the resilience and longevity of RC structures. This study contributes to the ongoing efforts to advance sustainable and robust infrastructure solutions.
