摘要：

The　method　for　calculating　the　lateral　stiffness　of　partially-restrained　steel　frame　with　RC　infill　walls　was　studied　to　provide　a　referrence　for　elastic　deformation.　Based　on　the　experimental　investigation　of　ten　one-bay,　two-story　partially-restrained　steel　frame　with　reinforced　concrete　walls　(PSRCW)　on　one　third　scale　under　low　reversed　cyclic　loading,　overall　stiffness　and　stiffness　reduction　of　PSRCW　were　analyzed.　The　results　show　that　PSRCW　has　large　lateral　stiffness　and　slowly-degraded　stiffness.　Thickness　of　infill　wall,　type　of　shear　connector　and　concrete　strength　have　large　effect　on　initial　lateral　stiffness,　but　type　of　PR　connection　and　quantity　of　shear　connector　have　little　effect　on　stiffness.　Calculation　method　for　the　initial　lateral　stiffness　of　PSRCW　is　proposed　through　deformation　analysis　of　PSRCW.　The　calculated　values　of　the　lateral　stiffness　match　well　with　the　experimental　ones.
