High-strength　centrifugal　precast　(HSCP)　reinforced　concrete　(RC)　hollow　pipe　columns　using　grouted　corrugated　duct　connection　(GCDC)　is　a　novel　structure　form　in　accelerated　bridge　construction　(ABC).　Nevertheless,　the　confinement　effect　of　the　HSCP　hollow　column　core　concrete　provided　by　single-layer　transverse　rebar　and　its　impact　on　ductility　is　not　clear.　Therefore,　in　this　paper,　the　confinement　effect　and　the　ductility　of　hollow　columns　is　studied　using　finite　element　analysis　(FEA)　method.　A　modified　model　is　established　to　evaluate　the　constitutive　relation　of　the　core　concrete　confined　by　single　layer　transverse　rebar.　Based　on　the　modified　model,　a　simplified　fiber　model　for　predicting　the　hysteric　response　of　HSCP　hollow　pipe　column　using　GCDC,　which　considers　bond-slip　effect　in　GCDC　joint　was　developed.　The　results　indicate　that　the　confinement　effect　of　HSCP　hollow　pipe　column　is　sensitive　to　the　wall　thickness　ratio.　When　the　wall　thickness　ratio　decreases,　the　ultimate　strain　of　the　core　concrete　significantly　decreases,　while　the　effect　on　strength　is　not　significant.　The　simplified　model　which　considers　confinement　effect　is　more　accurate　in　predicting　the　ductility　of　HSCP　hollow　columns.　It　proves　that　the　weak　confinement　effects　can　lead　to　early　cracking　of　the　inner　wall　of　hollow　columns,　which　leads　a　significant　impact　on　the　ductility　of　HSCP　hollow　columns.　Based　on　the　parametric　analysis,　the　peak　load　of　the　hollow　column　increases　by　16.7%　when　the　wall　thickness　ratio　rises　from　0.1　to　0.2,　but　only　slightly　changes　when　the　wall　thickness　ratio　is　increased　beyond　0.2.　The　wall　thickness　ratio　of　HSCP　hollow　pipe　columns　should　be　set　above　0.2　to　ensure　the　strength　and　ductility.　In　addition,　a　ductility　evaluation　method　and　a　design　example　were　developed　to　guide　preliminary　ductile　design　of　HSCP　hollow　columns.
