Experimental and Analytical Study on Structural Behaviour of RC Beams Retrofitted with a Hybrid System of CFRP, GFRP, Mas Plates, and Concrete Jacketing

Michael Nii Sarbah Okine, Charles Kwame Kankam & Fredrick Ali Issifu · Asian Journal of Advanced Research and Reports · 2025

This study examines the flexural performance of reinforced concrete (RC) beams retrofitted with a first-time hybrid system comprising CFRP laminates, GFRP bars, mechanical anchorage plates, and concrete jacketing. Although similar retrofitting methods are increasingly adopted, de...
