Aimming at some cable-stayed bridges in China with wind barrier erection on their girders or not, their wind-resistant performaces, such as flutter stability, vortex-induced vibration stability and aerostatic force coefficient, are investigated by wind tunnel tests considering the influence of wind barrier. The conclusions are different from some comprehension before and the new findings are useful for the cable-stayed bridge constructed in strong wind prone area adopting wind barrier to improve the driving safety of passing vehicles in windy.
