Abstract

This study investigates the interference effects between two rectangular-section high-rise buildings by wind tunnel experiments, focusing on local peak pressure coefficients. Wind tunnel experiments were carried out under 72 wind incidence angles for various configurations. Two building arrangements were considered: parallel and perpendicular. To evaluate the interference effects for local peak pressures in detail, interference factors for largest positive and smallest negative peak pressures are presented and discussed. The results show that interference effects greatly depend on configuration and wind direction. Unfavorable positions are generally concentrated at the edges and corners of a building. Flow visualization was also conducted to check the flow field between two buildings.
