| Abstract | ABSTRACT: Wind tunnel test of aeroelastic full model of Sutong Bridge is introduced, and special aerodynamic instability style was observed. The aeroelastic full model is regarded as a non-normal vibration system, and the vibration characteristics are investigated and analyzed. Complex modal analysis is carried out using SSA (Stochastic Search Algorithm) and SSI (Stochastic Subspace Identification). The results of both methods are agreed well. The torsional mode participates largely in vertical and lateral vibration, while the vertical and lateral modes have a little participation in the other two modes respectively. |
