Abstract

The influence of interference between two high-rise building models on the minimum peak pressures was investigated in an atmospheric boundary layer wind tunnel. Pressure measurements were performed on a square model with an aspect ratio of 1 to 4. The influence of an interfering model with the same height as well as half the height was investigated. A square full-height model resulted in minimum peak pressures on the facades 50% larger than observed in the isolated configuration. This increase was not observed for a circular full-height model. Both a square and circular half-height model resulted in increases of 30% on the facades at the same height as the roof of the interfering model. This paper gives a detailed discussion of these increases in terms of the wind behaviour and types ofinterference (i.e. channelling, buffeting and shielding)
