In　order　to　study　the　seismic　performance　of　wall-beam　out-of-plane　joints　with　ECC　post-cast　area,　seven　specimens　and　one　comparison　specimen　were　designed　considering　the　embeded　method　of　reinforcement　in　the　wall,　the　connecting　method　of　reinforcement　in　the　post　cast　area,　the　shear-to-span　ratio,　the　slab　width,　etc,　and　the　proposed　static　tests　were　carried　out.　The　damage　model,　hysteresis　performance,　bearing　capacity,　stiffness　degradation,　and　energy　dissipation　capacity　of　the　specimens　were　analyzed　and　the　simulation　method　based　on　the　finite　element　software　OpenSEES　is　given.　The　results　show　that:　the　use　of　ECC　in　the　postcast　area　can　effectively　improve　the　ductility　and　load-bearing　capacity　of　the　specimens;　the　use　of　bent-up　reinforcement　lap,　bent-hook　reinforcement　connection　and　sleeve　connection　for　the　reinforcement　in　the　post-cast　area　can　effectively　transfer　the　reinforcement　stress;　the　finite　element　analysis　method　proposed　in　this　paper　considering　the　slip　of　reinforcement　and　the　characteristics　of　ECC　material,　has　high　accuracy　and　is　suitable　for　application　in　engineering.
