Investigating　the　mechanical　properties　of　Galfan-coated　steel　cables　at　elevated　temperatures　is　important　for　the　fire-resistant　design　and　fire-simulation　analysis　of　pre-stressed　structures.　Unlike　conventional　structural　types,　Galfan-coated　steel　cables　comprise　several　steel　wires　encircling　a　core　wire　in　different　layers.　The　overall　mechanical　property　of　a　Galfan-coated　steel　cable　is　attributed　to　the　individual　properties　and　collaborative　mechanism　of　Galfan-coated　steel　wires.　The　mechanical　properties　of　a　Galfan-coated　steel　cable　at　elevated　temperatures　are　substantially　different　from　those　of　conventional　structural　steel　or　the　single　steel　wire.　In　this　study,　42　Galfan-coated　steel　cables　with　19,　37,　and　61　wires　were　tested　under　steady　state　tension　at　ambient　and　elevated　temperatures　ranging　from　100　to　600　degrees　C.　The　test　results　show　that　the　cables　exhibit　typical　non-linear　characteristics　with　a　lower　proportional　limit　and　no　clear　yield　plateau.　The　reduction　factors　in　the　mechanical　properties　of　Galfan-coated　steel　cables　at　elevated　temperatures　are　obtained　and　compared　with　values　predicted　in　Eurocode　2　part　1-2　and　ACl　216,　and　other　studies.　Equations　for　nominal　yield　strength,　elastic　modulus,　ultimate　strength,　and　ultimate　strain　for　Galfan-coated　steel　cables　at　elevated　temperatures　are　proposed　in　this　study.　Furthermore,　a　modified　two-stage　Ramberg-Osgood　model　for　Galfan-coated　steel　cables　at　ambient　and　elevated　temperatures　is　proposed.　(C)　2019　Elsevier　Ltd.　All　rights　reserved.
