| Abstract: | Modal analysis method of aeroelastic full model of cable-supported bridges is introduced. Based on the characteristics of full model of cable-supported bridges, the factors that will affect the results of modal analysis are discussed. As an example, the modality of full model of Runyang suspension bridge is anlysised by this method. |
