چکیده مقاله:
Wind loads on buildings in real environments can be quite different from those measured on isolated buildings. Surroundings can significantly increase or decrease the wind forces on the interfered buildings. Improvements of computer facilities and computational fluid dynamics (CFD) software in recent years have enabled prediction and assessment of the pedestrian wind environment around buildings.In this paper, peak pressure coefficients between two buildings were studied by using CFD for various heights of buildings in a row and the normal wind direction. The measured pressure coefficients were compared to those obtained from a study on an isolated building. Furthermore, the mean interference effects between two tall buildings were studied. It is shown that IF(min) increased with increase in height ratios of an interfering building (range of IF(min) is 0.85 for Hr=0.5 to 4.59 for Hr=2). Obtained results for the studied interference effects between two tall buildings are presented and discussed
