The　design　level　of　transmission　towers　in　China　can　be　improved　and　steel　product　consumption　for　it　can　be　reduced　by　adopting　cold-bending　profile　steel　to　transmission　tower.　Based　on　the　structural　features　of　transmission　tower,　the　cold-bending　angle　steel　members　with　different　cross-sections　and　slenderness　ratios　are　chosen　for　bearing　strength　test　under　axial　compression　and　finite　element　analysis,　thus　the　load-strain　law　and　ultimate　bearing　capacities　of　cold-bending　angle　steel　members　of　transmission　towers　under　axial　compression　are　obtained,　and　the　obtained　ultimate　bearing　capacities　are　compared　with　the　bearing　capacities　calculated　by　active　design　specifications.　Analysis　results　show　that　current　specification　system　is　unsuit　to　the　strength　design　of　axial-compressed　cold-bending　angle　steel　members　for　transmission　towers　in　China.　Through　the　fitting　of　test　results　with　theoretical　analysis　results,　the　stability　coefficient　curve　of　axial-compressed　cold-bending　angle　steel　members　for　transmission　towers　is　decided　and　some　modification　suggestions　on　bearing　capacity　calculation　of　cold-bending　angle　steel　members　for　transmission　towers　are　proposed.
