The　deformation　of　stainless　steel　cables　at　elevated　temperatures　is　an　important　consideration　for　the　design　of　fire　resistant　pre-stressed　spatial　structures.　In　this　paper,　by　conducting　extensive　experiments　on　a　number　of　specimens,　the　thermal　expansion　under　a　stress-free　state,　the　deformation　under　thermo-mechanical　coupling　state　in　transient　heating　stage,　and　the　creep　deformation　in　constant　temperature　stage　of　stainless　cables　subjected　to　elevated　temperature　were　studied　experimentally.　A　correlation　for　the　thermal　expansion　coefficient　of　the　stainless　steel　cables　in　the　range　of　30-600　degrees　C　was　obtained.　In　addition,　an　equation　relating　the　deformation　of　the　cables　and　the　temperature　and　initial　stress　under　the　thermo-mechanical　coupling　state　in　the　heating　stage　was　proposed.　Furthermore,　the　relationship　between　the　parameters　of　the　Field　&　Field　creep　model　and　the　temperature　was　derived　for　the　stainless　steel　cables.
