The　study　investigated　the　performance　of　a　specific　full-scale　precast　concrete　interior　joint　using　many　connected　methods　(e.g.　grouted　sleeves,　anchorage　arrangements,　corbels)　in　the　core　region　of　joint,　whilst　a　monolithic　cast-in-place　concrete　specimen　served　as　a　control.　The　important　indexes　in　terms　of　failure　mode,　hysteretic　behavior,　strength,　deformation　performance,　and　stiffness　degradation　were　investigated　under　low　reversed　cyclic　loading.　The　new　cross-lapping　connection　of　concrete　slab　was　presented　and　the　position　of　the　interface　between　two　layers　of　lamination　slab　was　optimized.　The　experimental　and　analysis　results　indicated　that,　(1)　the　precast　concrete　specimens　were　capable　of　matching　peaking　strength　and　deformation　performance　of　the　monolithic　cast-in-place　joint,　while　the　displacement　ductility　and　failure　modes　of　two　joints　were　different;　(2)　the　elastic-plastic　boundary　of　1/550　which　was　used　to　evaluate　precast　structures　should　be　carefully　selected　in　the　design;　(3)　an　effective　range　for　the　thickness　ratio　of　upper　layer　(post-pouring　concrete)　and　lower　layer　(precast　concrete)　was　presented;　(4)　a　new　cross-lapping　connection　for　bend-up　reinforcement　at　the　ends　of　the　semi-precast　slab　was　performed　for　another　optional　method.
