In　this　study,　bond　failure　tests　were　carried　out　on　eight　beam　anchorage　specimens　after　accelerated　corrosion,　and　the　crack　widths　on　the　concrete　surface　and　the　nonuniform　corrosion　characteristics　of　the　reinforcing　bars　were　analyzed.　The　testing　results　show　that　the　pitting　volume　and　maximum　crack　width　on　the　concrete　surface　both　increase　exponentially　as　the　mass　loss　rate　increases.　According　to　the　testing　results,　the　pitting　coefficient　and　uniform　coefficient　are　introduced　to　reflect　the　effect　of　the　pitting　corrosion　and　uniform　corrosion,　respectively,　on　the　bond　strength,　and　as　these　two　coefficients　increase,　the　bond　strength　greatly　decreases.　In　addition,　based　on　the　maximum　crack　width　on　the　concrete　surface,　bond　strength　and　peak　slip　models　are　developed,　and　a　bond　stress-slip　model　of　the　nonuniformly　corroded　reinforcing　bar　is　proposed,　combined　with　that　of　uncorroded　reinforcing　bar.　It　is　proved　that　the　proposed　models　provide　good　predictions.
