Abstract
In many cases of the wind load estimates, the fluctuating components of wind force are treated to be proportional to fluctuating components of wind. Because the fluctuating components of the wind are much smaller than the mean wind velocity and the quadratic term of the component in the wind force expression is omitted. Some of recent reports of strong wind observation, however, indicate that the gust factor becomes over 2 or that intensity of turbulence reaches to 30%. In this paper, the influences of the quadratic term on the overall wind force in high gust factor are discussed.
