In　order　to　evaluate　the　seismic　performance　of　precast　column　of　assembled　monolithic　subway　station,　three　full-scale　precast　concrete　interior　columns　and　three　full-scale　cast-in-place　concrete　interior　columns　were　designed　based　on　the　assembled　monolithic　subway　station　in　Beijing.　Main　seismic　behaviors　of　interior　columns　were　studied　under　low-cyclic　reversed　loading,　such　as　failure　modes,　hysteretic　characteristics,　bearing　capacity,　deformation　capacity,　energy　dissipation　capacity　and　optimum　axial　compression　ratio　under　different　axial　compression　ratios　(0.2,0.5,0.85).　The　results　show　that　the　horizontal　bearing　capacity　of　columns　increases　while　the　deformation　capacity　and　energy　dissipation　capacity　decrease　with　the　increase　of　axial　compression　ratio.　The　failure　modes　are　almost　similar　under　the　same　axial　compression　ratio,　but　the　position　of　plastic　hinge　of　precast　column　moves　upwards　gradually.　Although　the　deformability　of　precast　columns　is　worse　than　that　of　cast-in-place　columns　when　the　axial　compression　ratio　is　0.2,　the　results　are　opposite　when　the　axial　compression　ratios　are　0.5　and　0.85.　Especially,　the　advantage　of　precast　column　is　obvious　when　the　axial　compression　ratio　is　0.5.　The　energy　dissipation　capacity　of　precast　column　decreases　with　the　increase　of　axial　compression　ratio　and　it　dereases　significantly　compared　with　cast-in-place　concrete　column.　The　ductility　of　precast　column　is　1.16-1.33　times　of　cast-in-place　column　and　they　decrease　gradually　with　the　increase　of　axial　compression　ratio,　but　decreased　degree　of　displacement　ductility　of　precast　columns　is　obviously　larger　than　that　of　cast-in-place　columns.　Based　on　bearing　capacity　and　deformability　with　the　same　axial　compression　ratio,　the　appropriate　axial　compression　ratio　is　suggested　to　be　about　0.5.　©　2018,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
