The Anchorage Behavior of FRP EBR in the Plastic Zone of RC Beams

In this paper the bond behavior of external FRP reinforcement anchored in an high stressed zone of RC beams has been investigated under monotonic and cyclic actions. The detailed study of the experimental strain distributions along the FRP strengthening has evidenced a progressive damage of bond at increasing the cycles and the influence of steel yielding propagation under both monotonic and cyclic load histories.
