This　paper　focuses　on　the　strength　reduction　factor　spectra　for　self-centering　(FS)　model　subjected　to　near-fault　ground　motions　with　pulse-type　based　on　nonlinear　dynamic　analysis　of　single　degree　of　freedom　(SDOF)　system.　In　order　to　investigate　the　influence　of　the　the　FS　model　on　the　strength　reduction　factor,　the　ratio　of　the　strength　reduction　factor　of　the　FS　model　and　that　of　Elastic-Perfectly-Plastic　(EPP)　model　is　evaluated　and　discussed.　The　ratio　is　larger　than　1.0　and　the　maximum　value　can　reach　1.35　during　medium　and　long　period.　This　result　indicates　that　it　is　conservative　for　the　structural　design　of　the　self-centering　structure　when　the　strength　reduction　factor　for　EPP　model　is　used.　The　investigations　of　the　effects　of　the　post-yielding　stiffness　ratio　and　the　energy　dissipation　ratio　of　the　self-centering　model　on　the　strength　reduction　factor　are　also　carried　out.　©　2020　IOP　Publishing　Ltd.　All　rights　reserved.
