Title

Experimental Investigation on Mechanical Performance of Anchorage Systems for Externally Bonded FRCM Composite in Flexural Strengthening of RC Beams

Abstract

Experimental works revealed that anchorage systems were able to increase the efficiency of fibre reinforced polymers (FRP) in terms of the flexure or shear capacities and ductility performance of structural members. This task was conducted to investigate the suitability and effectiveness of two anchorage systems for enhancing the bond performance of fibre reinforced cementitious matrix composite (FRCM). On the behalf of improving its flexural performance, two anchorage systems were included in this study: a glass spike anchor and novel U-wrapped anchor. Real-scale simply supported RC beams were examined under the effect of strengthening with different reinforcement ratios and with and without anchorage systems engagement. Test results revealed the contribution of anchorage systems in preventing or delaying the FRCM debonding failure mechanism and enhancing the flexural performance of strengthened beams.
