Abstract
In this paper, presented at CRRELs First International Conference on Snow Engineering, the method used for determining the design snow loading for the large, arched roof and retractable roof structure of the Toronto Skydome is described. In this method, snow drifing on the roof of the Skydome was computed from the wind velocity patterns near the roof surface using a finite area element computer model. The velocity patterns were determined as a function of wind direction and spred by detailed wind tunnel tests. Meteorological records of wind, snowfall, rainfall and temperature were used as input to the program as it computed the snow load accumulations in a time step manner. From computed time histories of snow load patterns, design load cases were selected. The calculation of these snow load cases assisted in determining overall maximum loads, non-uniform loading situations and relative deflection of adjacent, separate roof segments.
