AbstractWind pressure records ranging in length from 15 minutes to about one hour, taken from twelve simultaneously recorded pressure transducers located at two levels in a 400 ft high office building in downtown Montreal were analysed to determine mean pressures, variances, spectral functions, and for selected pairs of transducers, cross-spectral functions. The measurements were made during five different windstorms in the period from 5 March 1964 to 2 March 1966. Most of the pressure measurements are supplemented by simultaneous recordings of wind direction and wind speed at 800 ft height from a wind vane and anemometer at a nearby location. The paper provides information on the relation between turbulence in a strong wind in a city environment and the wind pressure fluctuations on an actual building. Preliminary work in co-operation with the University of Western Ontario to compare the full-scale measurements with wind-tunnel measurements indicates that successful simulation of the basic statistical properties of wind pressure fluctuations can be obtained through the use of model complexes in a boundary layer type of wind tunnel.
