The　purpose　of　this　study　was　to　experimentally　investigate　the　behavior　of　a　partially-restrained　steel　frame　with　RC　walls　with　top-and　seat-angle　with　double　web-angle　connections　(PSRCW)　under　cyclic　lateral　loads.　A　total　of　six　1/3　scaled　one　bay,　and　two　story　test　specimens　were　built　and　tested.　The　hysteretic　behavior,　stiffness　degradation,　plastic　deformation　capacity,　ductility　and　energy　dissipation　capacity,　force　transmission　and　failure　modes　were　analyzed　in　detail.　The　results　indicate　that　PSRCW　shows　large　stiffness　and　lateral　strength,　while　it　shows　moderate　energy　dissipation　capacity.　At　the　design　load　level,　the　shear　connected　with　steel　beam　resist　about　80%　of　the　total　lateral　load,　and　steel　frame　resists　approximately　70%　of　the　overturning　moment.　Shear　connectors　subjected　to　combined　cyclic　shear　and　tension　forces　would　induce　low　cyclic　fatigue;　the　performance　improvement　of　shear　connectors　would　increase　the　ductility　of　PSRCW.
