Corroded　RC　columns　do　not　possess　necessary　ductility　to　dissipate　seismic　energy　during　a　major　earthquake,　the　study　investigates　the　use　of　hybrid　fiber　reinforced　polymer　(FRP)　wrapping　as　a　method　of　retrofitting　non-ductile　corroded　RC　columns,　and　a　model　to　determine　the　envelope　response　of　RC　corroded　columns　strengthened　with　hybrid　FRP　are　presented　based　on　cross-section　analysis　for　undamaged　RC　element.　The　results　show　that　the　technique　of　strengthening　corroded　RC　column　with　hybrid　FRP　is　quite　effective,　the　envelope　curve　estimated　using　the　linear　plane　assumption　with　modification　by　reinforcement　slip　model,　may　still　be　used　as　the　envelope　curve　of　RC　corroded　columns　strengthened　with　hybrid　FRP,　a　good　agreement　between　analytical　and　experimental　results　is　observed.
