| Abstract: | This paper analyzes the wind-resistant behavior of a single pylon cable-stayed bridge with the steel box girder. Firstly,the static force coefficients of the main beam section are obtained by means of the CFD numerical simulation and the wind-induced lateral-torsional buckling mechanism is analyzed. Then,dynamic characteristics of the bridge are analyzed to make a further research on the wind-induced vibration. Finally,the aerostatic response is calculated to evaluate the wind-resistant behavior of the bridge. |
