摘要：

In　order　to　improve　seismic　performance　of　partially-restrained　steel　frame　with　reinforced　concrete　walls　(PSRCW),　concealed　vertical　slits　were　used　in　the　solid　infill　walls.　The　one-bay,　two-story　test　specimen　on　one-third　scale　was　carried　out　under　low　reversed　cyclic　loading.　The　failure　mechanism　and　hysteretic　behavior　of　PSRCW　with　concealed　vertical　slits　were　investigated.　Experimental　studies　show　that　infill　walls　with　concealed　vertical　slits　has　little　effect　on　overall　elastic　stiffness　of　the　specimen,　however　enhance　the　structural　deformation　and　ductility.　PSRCW　with　concealed　vertical　slits　can　not　only　provide　certain　stiffness　under　the　moderate　level　of　earthquake,　but　also　supply　enough　capacity　of　deformation　and　energy　dissipation　under　the　rare　level　of　earthquake.
