Abstract：

Elastic　cable　for　damping　device　is　used　widely　in　the　medium-span　cable-stayed　bridge　for　its　simple　structure　and　low-cost.　In　order　to　study　the　elastic　cable　stiffness　estimation　method　for　long-span　cable-stayed　bridges,　this　paper　firstly　estimates　the　optimal　stiffness　of　the　elastic　cable　of　a　large-span　cable-stayed　bridge　by　the　simplified　formula　commonly　used　for　medium-span　cable-stayed　bridges,　and　then　uses　the　response　spectrum　analysis　method　to　determine　the　elastic　cable.　The　analysis　of　the　optimal　stiffness　values　shows　that　the　simplified　method　for　estimating　the　optimal　stiffness　of　elastic　cables　is　also　applicable　to　long-span　cable-stayed　bridges.
