Abstract

This work presents experimental results on the performance of Aramid Fiber Reinforced Polymer (AFRP) laminates used in the flexural retrofitting of full-scale reinforced concrete beams. The effects of variables including reinforcement placement, retrofitting orientation, and AFRP lifespan are examined. The experimental findings provide compelling evidence that structurally damaged beams can be retrofitted with AFRP composite material to restore their strength and stiffness. In most cases, the retrofitted beams perform as well as, if not better than, the control beams. The efficiency of the AFRP strengthening method in flexure, however, was found to vary with beam length. The examinations revealed that plate debonding was the leading cause of the failures observed. In order to overcome this difficulty, it is crucial to enhance the bonding processes between the AFRP laminates and the concrete substrate


Keywords: Aramid Fibre Reinforced Polymer (AFRP), Retrofitting, Laminate, Rupture of reinforced concrete beam, Debonding.
