This　study　investigated　the　seismic　performance　of　6-,　9-,　and　12-story　concentrically　braced　steel　frames　utilizing　shape　memory　alloy　slip　friction　dampers　(SMASFDFs).　For　comparison　purposes,　identical　frames　equipped　with　self-centering　braces　(SCBFs)　and　buckling-restrained　braces　(BRBFs)　were　also　designed　and　analyzed.　The　seismic　performance　of　considered　frames　was　evaluated　through　nonlinear　static　and　nonlinear　time　history　analysis　(NLTHA)　under　three　seismic　hazard　levels,　i.e.,　frequently　occurred　earthquakes　(FOE),　design　basis　earthquakes　(DBE),　and　maximum　considered　earthquakes　(MCE).　Incremental　dynamic　analysis　(IDA)　was　conducted　to　examine　the　seismic　responses,　including　peak　interstory　drift　ratios　(PID),　peak　floor　accelerations　(PFA),　and　residual　interstory　drift　ratios　(RID),　of　the　designed　frames　under　varying　levels　of　seismic　intensity.　Fragility　curves　considering　single　and　multiple　seismic　responses　were　obtained　based　on　the　IDA　results.　The　results　show　that　the　SMASFDFs　have　comparable　deformation　control　capacity　as　the　BRBFs　while　exhibiting　zero　RID　and　more　uniform　deformation　distribution　over　the　building　height.　Moreover,　in　most　circumstances,　the　joint　failure　probability　is　lowest　for　the　SMASFDFs　when　considering　multiple　seismic　responses.　From　a　seismic　design　perspective,　current　results　suggest　that　the　SMASFDFs　can　be　designed　with　the　same　strength　reduction　factor　(R)　if　the　PID　is　especially　concerned.　©　2024
