<![CDATA[Over the past twenty years, interest in using Carbon Fiber Reinforced Polymer (CFRP) to strengthen Reinforced Concrete (RC) columns has grown. To address the problem of load eccentricity, researchers have widely resorted to combining traditional methods, CFRP jackets, and Near-Surface-Mounted (NSM) CFRP bars. This paper presents experimental and numerical research on the effectiveness of using hybrid CFRP that merges the advantages of both NSM-CFRP column strengthening and External Bonded (EB) strengthening. Testing was carried out on four square RC columns (200×200 mm) under biaxial loads, and the results were validated using Finite Element (FE) analysis. Test data indicate that the hybridization technique significantly improves the overall performance of the strengthened RC columns, including crack pattern, ultimate load capacity, lateral displacement, and failure modes. The results indicated that RC columns achieved a higher ultimate load capacity with the hybrid approach, exceeding that of traditional columns by more than 55%. Furthermore, the combination of a CFRP jacketing with NSM-CFRP bars resulted in a lateral response improvement of up to 15%. Numerical simulations showed commendable agreement with experimental results, confirming that strengthening RC columns with hybrid-CFRP technology improves load-carrying capacity and reduces axial strains.]]>
