Abstract: External wrapping or retrofitting of polymer sheets are used in concrete and reinforced concrete structures is an increasing trend present. This paper evaluates the flexural behavior of beams retrofitted externally with GFRP laminates. Experimental plan deals with static experimental analysis. Reinforced beams of sizes 200×250×3500mm are casted for a grade of M35. Reinforced beams are externally retrofitted with E-glass fiber polymers. Beams are epoxy bonded to the GFRP laminates. Beams are tested under monotonic two point concentrated loading. Load – Deflection characteristics, crack pattern and failure characteristics of beam are analyzed.
Keywords: Retrofitting, GFRP laminates, numerical analysis, experimental analysis.
