摘要：
The aerodynamic stability becomes a governing factor in designing long-span suspension bridges. In this paper, using the method of three-dimensional nonlinear aerodynamic stability analysis, parametric analyses on the aerodynamic stability of the Runyang bridge over the Yangtze River are performed including the structural system, the cable sag, the side span length, the depth, dead load and Supporting system of the deck, etc. Some important design parameters that affect the aerodynamic stability of the bridge are pointed out, and the favorable structural system of the bridge is also discussed based on the wind stability.
