Based　on　the　experimental　investigation　of　three　one-bay,　two-story　partially-restrained　steel　frame　with　reinforced　concrete　infill　walls　(PSRCW)　at　1/3　scale　under　low　reversed　cyclic　loading,　the　hysteretic　behavior,　deformation　character,　and　failure　mode　of　different　type　of　shear　connectors　in　PSRCW　are　analyzed.　The　results　show　that　hysteretic　curves　of　shear　connectors　display　an　invert　＇S＇　shape,　and　exhibit　obvious　slipping　character.　The　failure　modes　of　three　types　of　shear　connectors　are　concrete　crush　on　the　basis　of　shear　connectors.　Channel　shear　connector　possesses　the　highest　shear　stiffness,　and　the　smallest　interface　slip.　Headed　stud　has　the　lowest　shear　stiffness,　and　U　shape　deformed　steel　bar　has　moderate　shear　stiffness.　The　shear　connectors　in　PSRCW　sustained　combined　shear　and　tension,　especially　lied　in　the　corner　region　of　infill　walls.　According　to　mechanism　character　of　shear　connector　in　PSRCW,　rational　design　method　is　proposed.
