To　design　prefabricated　concrete　columns　with　grouted　sleeves　(PCC-GSs),　the　development　and　damage　process　of　the　plastic　hinge　(PH)　regions　for　the　PCC-GSs　need　to　be　clarified.　In　this　study,　a　finite　element　analysis　(FEA)　method　for　the　PCC-GSs　was　verified　through　experimental　results,　including　the　failure　modes,　load-displacement　responses,　and　physical　plastic　hinge　lengths　(PHLs).　Consequently,　a　series　of　finite　element　models　(FEMs)　were　constructed.　The　effects　of　parameters　such　as　grouted　sleeve　(GS)　height,　axial　force　ratio,　and　shear　span　ratio　on　the　PHL　for　the　PCC-GSs　were　systematically　analysed　under　cyclic　loading.　Finally,　with　the　discussion　of　the　existing　empirical　models　for　the　equivalent　PHL　(Lp),　a　simplified　calculation　model　of　Lp　for　PCC-GSs　was　proposed　and　evaluated.　The　results　indicate　the　following.　(1)　The　PH　of　PCC-GSs　may　move　up　or　down,　and　its　PH　development　mode　is　significantly　different　from　that　of　the　CIP　RC　column.　(2)　The　axial　force　ratio　n,　shear　span　ratio　z/d,　longitudinal　reinforcement　ratio　rho　s,　rebar　yield　strength　fy,　and　GS　height　LGS　all　have　a　significant　influence　on　the　PH　region　of　PCC-GSs,　especially　LGS.　(3)　The　proposed　model　is　more　suitable　to　calculate　the　PHL　for　PCC-GSs　with　considering　the　effects　of　LGS,　n,　z/d,　rho　s,　fy.
