In　order　to　study　the　seismic　performance　of　stainless　steel　end-plate　beam-to-column　joints,　six　full　scale　end-plate　beam-to-column　joint　specimens　were　designed　and　fabricated,　including　five　stainless　steel　joints　and　one　carbon　steel　joint　in　grade　Q345B.　Quasi-static　loading　tests　on　the　six　joint　specimens　were　carried　out,　and　the　failure　modes,　hysteresis　curves　and　structural　properties　were　obtained.　By　means　of　the　finite　element　(FE)　software　package　ABAQUS,　the　cyclic　loading　process　of　the　tested　joint　specimens　was　accurately　simulated,　and　the　seismic　performance　of　the　joint　specimens　was　further　explored.　It　is　revealed　that　the　energy　dissipation　capacities　of　the　two　stainless　steel　beam-to-interior　column　joints　in　different　material　grades　are　close　to　each　other,　which　are　better　than　that　of　the　carbon　steel　counterpart.　The　hysteresis　curves　of　beam-to-interior　column　joints　are　more　stable　than　those　of　the　exterior　ones,　though　the　beam-to-interior　column　joints　display　relatively　lower　resistances.　Moreover,　the　presence　of　end-plate　stiffeners　contributes　significantly　to　the　seismic　performance　of　joints,　and　the　resistances　increase　by　around　30%　and　the　energy　dissipation　capacities　are　doubled.　The　numerically　obtained　values　of　the　joint　rotations　satisfy　the　ductility　demands　specified　in　the　current　seismic　design　standards,　indicating　favorable　seismic　performance　of　the　tested　joints.　©　2021,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
