| Abstract | In this paper, the static and dynamic wind-induced instability analyses of super long-span cable-stayed bridges with main span length of 1200~1800m are presented. Firstly, the static behaviors of bridges against displacement-dependent wind load are investigated by three-dimension geometrical nonlinear analysis. Secondly, the free vibration and flutter analyses are carried out and the comparison of dynamic structural properties between cable-stayed and suspension bridges are discussed. Finally, the possibility and limitations of long-span cablestayed bridges based on static and dynamic instability analyses are discussed. The analytical results show that static instability controls the dimension of the girder and the safety against both static and dynamic instabilities can be ensured even with main span length of 1800m. |
