Unsteady Theoretical Analysis on the Wake-Induced Vibration of Suspension Bridge Hangers

AbstractThe hangers on long-span suspension bridges are significantly prone to wind-induced vibrations due to their light mass, low frequency, and small structural damping. These vibrations are known to cause fatigue problems and impair the serviceability and safety of structures. The possibility of...
