Effect of wind incidence angle on wind pressure distribution on tall buildings

This paper presents the results of an experimental study carried out on the model of I-shape tall building to examine the wind pressure distribution on its different surfaces. The model of the building is tested in an open circuit boundary layer wind tunnel under varying wind incidence angles. Wind pressure values measured at numerous pressure points are used to calculate wind pressure coefficients and the experimental observations are presented in the form of pressure contours. It is observed that the magnitudes of pressure coefficients vary considerably with the location and wind direction.
