Two　1/6　scale　core　walls,　including　one　RC　core　wall　with　steel　tube-reinforced　concrete　columns　aid　concealed　steel　trusses　and　one　conventional　RC　core　wall,　were　tested　under　eccentric　horizontal　cyclic　loading.　The　load-capacity,　ductility,　hysteresis　characteristics,　stiffness,　stiffness　deterioration　process,　energy　dissipation　and　damage　characteristics　of　the　two　specimens　were　compared　and　discussed　in　this　paper.　It　shows　that　the　seismic　performance　of　the　RC　core　walls　under　combined　action　could　be　improved　by　setting　the　concealed　steel　trusses　in　the　walls　and　using　the　steel　tube-reinforced　concrete　columns　as　the　boundary　elements.
