WebDebonding failure at a plate end may occur through two paths: (1) interfacial debonding where a thin layer of concrete is peeled off, and (2) concrete cover separation in which the failure plane occurs at the rebar level where the concrete area is reduced by the existence of rebars. Debonding occurs at the weaker link of these two paths.
