Experimental Study on Bond Characterization of Hybrid-Bonded FRP to Concrete Interfaces

Abstract:

Pure adhesive bond of FRP to concrete is not only weak but also unreliable in a long term. This problem can be effectively overcome by a newly developed bond enhancement system the hybrid bonded FRP system (HB-FRP) in which small mechanical fasteners are used to augment the bond. In this paper, the bond behaviors of EB-FRP and HB-FRP joints were experimentally investigated by employing the single shear pull-off test on three EB-FRP and seven HB-FRP specimens with different bond lengths. Experimental testing is reported for characterization of the interfacial bond of the HB-FRP system.
