This　paper　numerically　studied　the　collapse　capacity　of　high-rise　steel　moment-resisting　frames　(SMRFs)　using　various　width-to-thickness　members　subjected　to　successive　earthquakes.　It　was　found　that　the　long-period　component　of　earthquakes　obviously　correlates　with　the　first-mode　period　of　high-rises　controlled　by　the　total　number　of　stories.　A　higher　building　tends　to　produce　more　significant　component　deterioration　to　enlarge　the　maximum　story　drift　angle　at　lower　stories.　The　width-to-thickness　ratio　of　beam　and　column　components　overtly　affects　the　collapse　capacity　when　the　plastic　deformation　extensively　develops.　The　ratio　of　residual　to　maximum　story　drift　angle　is　significantly　sensitive　to　the　collapse　capacity　of　various　building　models.　A　thin-walled　concrete　filled　steel　tubular　(CFST)　column　is　proposed　as　one　efficient　alternative　to　enhance　the　overall　stiffness　and　deformation　capacity　of　the　high-rise　SMRFs　with　fragile　collapse　performance.　With　the　equivalent　flexural　stiffness,　CFST-MRF　buildings　with　thin-walled　members　demonstrate　higher　capacity　to　avoid　collapse,　and　the　greater　collapse　margin　indicates　that　CFST-MRFs　are　a　reasonable　system　for　high-rises　in　seismic　prone　regions.
