This paper investigates the wind forces acting on two principal buildings interfered by a very closely located dummy building. For the study, the high-frequency force balancer is used to measure over-turning moments in the along-wind and cross-wind directions in a well-simulated turbulent boundary layer flow. The two principal buildings are made into a square and a tapered cylinder respectively; the dummy building is a square cylinder that produces various interference effects when its relative location to the principal building is adjusted. Results show that the response estimations for safety and habitability level may differ due to various interference effects and different shapes of principal buildings. Critical interference locations are found for significant wind-induced responses.
