In　order　to　evaluate　the　seismic　behavior　and　performance　of　the　overall　assembled　subway　station　and　promote　the　application　of　the　prefabricated　assembly　technology　in　underground　structures,　the　full-scale　prefabricated　beam-column-slab　interior　joint　(PMJ-1)　from　the　cross　section　of　station　and　the　full-scale　cast-in-place　concrete　beam-column-slab　interior　joint　(CMJ-1)　were　designed　and　fabricated.　The　important　indexes　were　studied　under　low-cycle　repeated　loading,　such　as　failure　mode,　hysteretic　characteristic,　bearing　capacity,　deformation　capacity,　energy　dissipation　capacity　and　stiffness　degeneration　etc.　The　results　show　that　the　distributions　of　cracks　are　slightly　different.　The　distribution　of　cracks　of　the　cast-in-place　concrete　joint　is　homogeneous,　but　the　distribution　of　cracks　of　the　precast　concrete　joint　is　localized.　For　the　precast　concrete　joint,　the　main　regions　of　cracks　were　distributed　along　the　plastic　zone　of　the　layered　slab　and　the　connection,　especially　the　superimposed　surface　between　precast　part　and　cast-in-place　part　of　the　layered　slab.　The　bearing　capacity,　initial　stiffness　and　energy　dissipation　capacity　of　beam-column-slab　joints　are　approximately　the　same　for　the　two　tested　joints,　but　the　displacement　ductility　coefficient　of　PMJ-1　is　about　1.6　times　of　that　of　CMJ-1.　Based　on　the　connection　type　and　the　details　of　PMJ-1,　the　grouting　sleeves　and　connecting　parts　of　prefabricated　member　are　simplified　in　the　finite　element　model.　The　numerical　analysis　results　agree　well　with　the　experimental　results.　The　seismic　performance　of　the　prefabricated　assembled　joints　is　not　weaker　than　that　of　the　cast-in-place　joints.　Both　the　experimental　results　and　the　numerical　analysis　lay　the　foundation　for　the　application　of　the　prefabricated　assembled　structures　in　underground　structures.　©　2019,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
