In　order　to　study　the　seismic　behavior　of　out-of-plane　wall-beam　joints　with　engineering　cementitious　composites　(ECC)　post　cast　zones,　seven　prefabricated　specimens　and　one　comparative　specimen　were　designed　and　loaded　considering　the　factors　of　embedded　mode　of　reinforcement　in　the　wall,　connection　mode　of　reinforcement　in　the　joint　area,　shear　span　ratio,　and　slab　width.　The　failure　mode,　hysteretic　performance,　bearing　capacity,　stiffness　degradation　and　energy　dissipation　capacity　of　the　joint　were　analyzed,　and　the　damage　process　was　analyzed　by　four　models.　The　results　show　that:　the　main　failure　mode　of　the　specimen　is　bending　at　the　end　of　the　beam,　and　the　wall　is　slightly　damaged;　ECC　can　effectively　improve　the　ductility　and　bearing　capacity　of　the　specimen　in　the　joint　area;　double-layer　reserved　welding　anchor　plate　in　the　wall　is　better　than　transverse　reinforcement　restraint;　using　bending　reinforcement　lap,　hook　reinforcement　connection　and　sleeve　connection　in　the　post　cast　area　can　effectively　transfer　the　stress　of　the　reinforcement;　the　plastic　energy　dissipation　model　can　better　reflect　the　damage　state　of　the　specimen　during　loading.　The　application　is　convenient　and　the　calculation　result　is　more　accurate.　©　2023　Science　Press.　All　rights　reserved.
