Influence of wind direction on pressure distributions of adjacent buildings

Wind tunnel experiments were carried out to investigate the influence of wind direction on the wind pressure of proximite buildings.Mean and fluctuating pressure coefficients on a high building,at sixteen different wind incidences and with one and two interfering buildings,were measured in the tests.This paper presents the characteristics of wind pressure on the building,which varies with the incident wind angle and with the numbers of adjacent buildins.Due to the variation of wind angle and the interference effects,the complex feature of pressure distributions can be found on the downstream building surfaces for building group arrangement at certain angle of wind attack.Some area of the interfered building for such configuration,in comparison with one single building's,may undergo very strong positive or negative pressures.
