摘要：

The　research　program　is　aimed　at　investigating　the　effectiveness　of　application　of　good　ductile　hybrid　fiber　reinforced　polymer　(FRP)　to　upgrade　corroded　RC　beams.　A　total　of　5　RC　beams　are　tested　under　flexural　load,　the　results　show　that　compared　with　the　un-strengthened　corroded　RC　beam,　the　crack,　yield,　maximum　and　ultimate　load　of　corroded　RC　beam　strengthened　with　hybrid　FRP　sheets　is　increased　by　14%,　35%,　102%　and　109%　respectively,　and　the　displacement　ductility　factor　is　only　decreased　by　11%,　which　indicate　that　the　hybrid　FRP　sheets　can　improve　significantly　the　flexural　performance　of　corroded　RC　beam.　©　(2011)　Trans　Tech　Publications.
