EXPERIMENTAL STUDY ON ENHANCING THE FLEXURAL STRENGTHENING OF PRE-LOADED RC BEAMS USING BFRP BARS

  • Abstract:
  • Reinforced Concrete (RC) beams are critical load-carrying elements in structures, designed to ensure stability through the combined action of concrete and steel reinforcement. To further enhance their flexural capacity, Basalt Fiber Reinforced Polymer (BFRP) bars can be used with strengthening methods like Side Near-Surface Mounted (SNSM) and Bottom Near-Surface Mounted (BNSM)techniques.This study experimentally investigates the flexural performance of preloaded RC beams strengthened using SNSM and BNSM methods. The beams were preloaded and then retrofitted with longitudinal BFRP bars embedded in grooves along the sides (SNSM) and bottom (BNSM). Comparative analysis between strengthened and control beams was performed by evaluating ultimate load, service load, deflection, and crack behavior.
