The　mechanical　performance　of　local　bending　cable　located　cable-strut　joint　is　analyzed　through　finite　element　analysis　and　experimental　research.　The　refined　finite　element　model　of　cable　under　tension-bending　coupling　effect　was　established　by　ABAQUS,　and　the　test　of　Galfan　cable　under　tension-bending　coupling　load　was　completed.　The　results　were　compared　with　mechanical　properties　of　cable　under　tension　load,　which　included　the　mode　of　failure,　breaking　strength　and　ultimate　strain.　And　the　refined　finite　element　model　of　cable　under　tension-bending　coupling　effect　is　verified　by　contrasting　with　the　test.　Analysis　shows　that　the　local　bending　of　cable　in　cable　clamp　end　leads　to　the　increase　of　the　extrusion　contact　area　of　wires,　which　affects　the　force　transmission　of　the　spiral　wire,　and　results　in　the　increase　of　local　stress,　leading　to　the　first　breaking.　Tension-bending　coupling　effect　has　an　adverse　impact　on　the　bearing　capacity　of　cable,　which　causes　the　ultimate　strain　to　decrease　significantly,　rendering　structure　brittle　failure.　It　is　significant　to　optimize　the　design　of　cable-strut　joint　and　to　pay　attention　to　safety　during　the　construction　process.　©　2017,　Editorial　Board　of　Journal　of　Tianjin　University(Science　and　Technology).　All　right　reserved.
