Abstract
The characteristics of wind pressures acting on a circular flat roof have been investigated, based on the data obtained from a wind tunnel experiment. A simple model of the pressure field is provided as a function of the geometric parameters of the building as well as of the turbulence parameters of the approach flow. A discussion is made of the application of the pressure field model to the wind load estimation, based on the gust effect factor approach and the LRC method. The gust effect factor and the equivalent static load distribution derived from the pressure field model are compared with those obtained from the time history of the pressures. The results indicate the validity of the pressure model.
