Abstract

A more rational approach to snow loads for the design of roofs in the National Building Code of Canada has resulted from a ten-year country-wide survey of actual snow loads on roofs. The objective of the survey was twofold: to determine by how much average roof loads can be reduced below the level of ground loads; and to assess factors that result in the accumulation of higher loads on particular areas of various shapes of roofs from the effects of wind, sliding, etc.This paper describes the factors that affect snow loads, the survey and its results, and present requirements for snow loads for the design of roofs in Canada.
