Snow distribution on low-rise roofs and practical analysis method

摘要

Snow related failures can have significant impact on the safety of people who occupy snow damaged buildings. So the research for snow distribution characteristics on the roofs can avoid personnel casualty and economic losses caused by heavy snowdrift. This paper outlines the current researches of snow distribution on surface of the different roofs and the methods of researching for snowdrifting. The practical calculation method of the snow load on the typical low rise buildings was investigated by comparison between the different countries load code for example China, America, Canada and Europe.
