Abstract
Wind pressure measurements made over a four-year period on a 34-story building in downtown Montreal were used to obtain data for checking and improving wind tunnel techniques of modeling flow characteristics of wind and aerodynamic behavior of buildings. It had been hoped that the measurements could be applied directly to certain problems of design, such as evaluation of peak suction load over small wall areas. However, the small number of pressures recorded, combined with limitations of field measurements, made direct application of the data extremely difficult. The major problems involved in making field measurements and in comparing them with wind tunnel measurements were found to be: difficulty in establishing a static reference pressure and its relation to the static pressure in the wind tunnel; inadequacy of wind velocity information, which in this case consisted of one anemometer and wind vane located 1,500 feet southwest of the building; and lack of stationarity and homogeneity of the velocity field as compared with the wind tunnel situatuion.
