Wind-resistant　performance　of　beam　string　structure　with　high-strength　steel,　which　adopts　wind　cable　or　not,　is　numerically　studied,　compared,　and　examined　here　by　finite　element　software　ANSYS.　It　is　shown　that　downward　vertical　displacement　tends　to　reduce　and　bottom　string　almost　linearly　relaxes　as　wind　suction　increasing,　and　overall　stiffness　of　the　structure　weakens　as　long　as　relaxation　of　bottom　string.　However,　wind-resistant　performance　favourably　improves　by　using　wind　cable,　whose　critical　wind　load　can　be　increased　about　6.55%　under　unit　self-weight　of　whole　structure.　The　wind-resistant　performance　also　enhances　with　the　increase　of　height　of　wind-resistant　strut.
