摘要

This study investigates the flexural behavior of reinforced concrete (RC) columns strengthened using Basalt Fiber Reinforced Polymer (BFRP) bars through the Near Surface Mounted (NSM) technique and a novel hybrid method combining NSM with Fiber Reinforced Polymer (FRP) jacketing. The research evaluates the performance of BFRP bars as a sustainable alternative to Glass Fiber Reinforced Polymer (GFRP) bars, considering their mechanical advantages and cost-effectiveness. Nine RC columns were cast and subjected to a constant axial load and gradually increasing lateral load until failure, with variables including strengthening technique, bar type (BFRP vs. GFRP), and bar diameter (10 mm and 12 mm). Results demonstrate that BFRP bars enhance flexural capacity, ductility, and ultimate load in both NSM and hybrid techniques. Notably, the hybrid technique reached 1.95 times the ultimate load of the specimen, underscoring its potential as a robust and sustainable strengthening solution. These findings contribute valuable insights into adopting hybrid BFRP-based systems for advanced structural applications.
