Abstract
Recent experience with wind-induced glass breakage in high- rise office towers has demonstrated the difficulty of pin- pointing potential problem areas on a building and hence the need for a better understanding of the magnitude and nature of cladding loads. Results of surface wind pressure measurements made simultaneously at 32 points on a 57-storey office tower in Toronto are reported. In addition to readings taken at 1/2-second intervals during high winds, mean and root-mean-square pressures were recorded for a 5- minute interval once each hour, and pressure coefficients referred to the free stream dynamic pressure at 286 m were computed for comparison with wind tunnel test information which was used in the design of the cladding.
