In　order　to　obtain　the　mechanical　properties　of　truss　cable　structure　under　cyclic　loading.　Taking　truss　cable　structure　as　the　research　object,　the　quasi-static　test　is　carried　out.　A　test　model　of　a　truss　cable　structure　with　a　span　of　7.5　m　was　established.　The　hysteresis　curve,　skeleton　curve,　stiffness　degradation　and　energy　dissipation　capacity　of　the　structure　were　analyzed,　and　the　failure　mechanism　of　the　structure　was　obtained.　The　correctness　of　the　finite　element　model　is　verified,　and　the　quasi-static　analysis　of　the　truss　cable　structures　with　different　structural　parameters　is　carried　out　to　obtain　the　influence　law　of　each　parameter　on　the　truss　cable　structure.　The　results　show　that　the　high-strength　cable　fully　enhances　the　downward　bearing　capacity　of　the　truss　cable　structure,　and　the　difference　in　the　upper　and　lower　hysteretic　properties　of　the　truss　cable　structure　is　obvious.　The　bearing　capacity　and　stiffness　of　the　cyclic　upward　loading　are　smaller　than　those　of　the　cyclic　downward　loading.　The　failure　mode　of　the　truss　cable　structure　is　the　strength　failure　of　the　lower　chord　member　after　buckling.　The　sag　and　rise　have　a　certain　influence　on　the　hysteretic　performance　of　the　truss　cable　structures,　and　the　prestress　has　no　effect　on　the　hysteretic　performance.
