<p>The bond degradation and degradation mechanism induced by corrosion-induced crack were investigated numerically using 3D RBSM in which rebar was modeled by solid elements without modeling explicitly the details of rebar ribs. The proposed method considers both corrosion expansion and shear stress transfer behavior from rebar by interface elements. Validation of the proposed model showed that it is possible to obtain reasonable bond performance of non-corroded specimen as mesoscale models and is capable of reproducing the bond deterioration caused by corrosion-induced crack. Finally, bond deterioration mechanism was investigated through the crack development and stress distribution, and the mechanism was found to be the combined effects of degradation of ring-tension stress around cracks and compressive stress near concrete cover, which induced by corrosion-induced crack.</p>
