WebJun 1, 2009 · Here, the bond strength and modes of debonding between the FRP laminates and reinforced concrete members strengthened in flexure are reviewed. … WebJan 1, 2012 · Conclusions. The results of a series of tests on forty-one FRP-to-concrete joints anchored with up to three FRP anchors, in addition to two tests on unanchored control joints, have been presented in this paper. In all cases, multiple anchors increased the strain utilisation of the FRP plate in relation to the unanchored control joints.
