Abstract
This paper, presented at CRRELs First International Conference on Snow Engineering, presents the results of observations which show that average values of snow load on roofs are usually lower than the average weight of precippitation that falls in winter. This is mainly caused by drift of snow by wind and snow thaw. The maximum snow drifts occur on flat roofs. The codes ofsome countries, in particular, USSR and Canada provide for a positive effect of wind in forming snow accumulations on such roofs. According to Canadian codes, the snow load on flat roofs are 20% less than for those of a complex shape, and snow load is decreased by 20% on flat roofs for regions with an average for many years of wind velocity over 4 m/s in the USSR cofdes. The investigatioans to obtain appropriate decreasing of snow loads for mentioned roofs were carried out in the USSSR, in connection with a great number of building constructed with flat roofs, amounting in area to some dozens of hectares. The main results of these investigations carried out by the authors are presented.
