In　order　to　evaluate　aseismic　performance　of　Fiber　Reinforced　Polymer　(FRP)　confined　reinforced　concrete　(RC)　rectangular　hollow-bridge　columns,　a　simplified　confined　concrete　model　of　FRP　is　proposed　by　considering　the　effective　strength　coefficient　and　area　distribution　ratio　of　FRP　hoops.　The　proposed　simplified　analytical　model　is　validated　to　be　right　and　effective　by　comparing　the　test　results　and　calculation　results　of　lateral　forces　vs　deformations　at　the　top　of　bridge　piers　and　rotation　deformations　vs　moments　at　the　bottom　section　of　bridge　column　specimens.　Based　on　the　improved　analytical　model　presented,　aseismic　performance　parameters　of　flexural　capacity,　curvature,　the　plastic　rotation　capacity　of　cross　sections　of　a　RC　rectangular　hollow　section　pier　restrained　by　different　types　of　FRP　are　investigated.　The　results　show　that　the　loop　packaged　FRP　cloth　has　a　more　considerable　effect　on　ductility　than　the　load　capacity　of　FRP　restricted　RC　rectangular　hollow-bridge　columns.
