The present study aims to investigate multiple wind effects on long-span twin-box girder bridges by developing a time-dependent nonlinear numerical scheme, which takes into account a range of aerodynamic forces, such as the stationary aerodynamic force, self-excited force, buffeting force and vortex-induced vibration (VIV) force. After calibration and validation, the developed scheme was implemented to investigate wind-induced behaviors of the Xihoumen Suspension Bridge. The results show that the developed scheme has the capability of simulating the nonlinear features of various types of bridge aerodynamic forces and can reproduced the flutter phenomenon from wind tunnel testing and the VIV ..View full abstract
