Abstract
Paper addresses maximum annual values of snow load on the ground at plain and mountainous regions of Krasnodar Krai, which served as a basis for establishing snow loads on buildings in SNKK 20-303-2002 "Loads and Actions. Snow Loads and Wind Actions". Given the fact that average annual temperature has increased by two degrees in Kuban region during last 30 years of observations it is important to estimate the influence of this shift on the values of snow loads and the possibility of future changes of snow loads. The research employs time series of snow-measuring observations during 1946–1999 for mountain regions and 1946-2012 for plain regions. Inversion criterion was used for assessing the significance of the linear trend of maximum annual values of snow load. Assessment was made for 20 meteorological stations in plain part of the region and for 3 snow courses in mountainous areas of West Caucasus at heights of 500 to 2000 m, including mountain cluster of the 2014 Winter Olympics Games Venues. It was established that in all cases with the level of statistical certainty 0.95 trend is absent. In the foreseeable future during next several decades snow loads in Krasnodar Krai may be assumed to remain stable, if characteristics of climate will not change under the influence of anticipated decrease of solar activity.
