Summary Tall buildings are vulnerable to lateral loading. The facades of these buildings are susceptible to wind loads. It is very difficult to assess the wind condition around the tall building in the presence of other surrounding buildings due to the wind interference effect. An experiment is carried out in the Boundary Layer Wind Tunnel at Tokyo Polytechnic University, Japan, to study the wind interference effect on tall buildings with varying plan ratios. The maximum and minimum local peak pressure coefficient contours on front face of the principal building are plotted. The interference effect is quantified in terms of interference zone charts. It is observed that interference zones extend over a larger area as the building plan ratios increases. The minimum interference factor depends on the plan ratios of the interfering building especially along the oblique direction. The results of this study may be useful for the preliminary design of cladding of tall buildings with interfering buildings.
