Abstract
Pressure measurements were performed on various configurations of two high-rise building models in two atmospheric boundary layer wind tunnels in the Netherlands. A comparison was made of the interference factors of the minimum and maximum peak pressures over all pressure taps at 0 degree angle of incidence obtained for measurements on the configurations with an interfering model of similar size and shape as the reference model. Both studies observed increases of 30-40% in the minimum and maximum peak pressure for the tandem arrangement configurations (Y = 0) with the interfering model at (X = 4B – 6B). Both studies furthermore determined that when the interfering model is positioned at a distance Y > 3B, there is no influence on the maximum peak pressures over all pressure taps. For an interfering model in the region (X, Y) = (2.5B – 6B, B – 6B), both studies observed increases in minimum peak pressure ranging between 10-50%.
