Abstract
In thin study, in order to evaluate the extreme value distribution of wind speed from each wind direction in consideration of Typhoon effect, the “Typhoon factor” was induced into the extreme wind speed expected from parent distribution characteristics obtained from usual wind speed measurement at local meteorological observatories in Japan.
Furthermore, the evaluation method of failure probability of a long span bridge due to strong wind was developed in taking the extreme distribution of directional wind speed, wind direction and its incident angle, aerostatic and aerodynamic response of the bridge into account.
