AbstractA countrywide survey of actual snow loads on roofs being made by the Division of Building Research to improve the snow loads specified in the National Building Code of Canada indicates that there are significant variations in the relationship of roof loads to ground loads, depending on a number of factors. The causes of these variations, mainly wind and roof shape, are discussed with examples of actual magnitudes and distribution of loads. While much of the information is not sufficiently complete to be incorporated into codes it is nevertheless of aid to the designer. Finally snow load specifications in other countries are discussed.
