摘要：

Many　RC　beams　not　only　were　damaged　by　the　aggressive　environment　but　also　were　subjected　to　the　cyclic　loads.　When　the　RC　beam　was　subjected　to　both　corrosive　environment　and　fatigue　load　at　same　time,　the　fatigue　life　of　the　beam　decreased　remarkably.　In　order　to　forecast　the　residual　life　of　the　existing　RC　structure　and　choose　the　adaptive　retrofitting　ways,　this　paper　summarizes　the　latest　research　achievements　about　the　fatigue　property　of　corroded　RC　beams,　analyzes　the　main　influence　factors　on　the　fatigue　life　of　the　corroded　RC　beams.　The　results　show　that　the　more　severe　environment　is,　the　lower　fatigue　life　of　RC　beam　is.　The　light　corrosion　level　of　steel　bar　may　result　in　a　significant　reduction　in　fatigue　life　of　RC　beam.　The　corroded　RC　beams　retrofitted　using　Fiber　reinforced　plastic　(FRP)　is　a　good　way　for　improving　the　fatigue　behavior.
