Abstract

Pressure measurements in a boundary layer wind tunnel on two tall building models in tandem arrangement are analysed in order to determine local wind loads relevant for façade design. The tests comprise measurements of 4 configurations over 24 wind directions. Mean and root-mean-square pressure contours are presented for two model faces. The results show that the so-called Venturi or channelling effect in a building passage is a flow phenomenon with highly unsteady features. Furthermore, the ratio of separation distance and building influence scale, w/S, appears to be a promising parameter to provide an indication for the influence on the local loads on buildings in tandem arrangement.
