Abstract
The study results of the snow load values’ high-altitude dynamics, the snow cover weight value and its change with height for the designed objects of all-season tourist and recreational complex “Elbrus” at the altitudes from 2000 m to 3840.6 m are presented. Monthly measurements of the snow cover height have been carried out at various heights for this purpose. Based on the results of the snow cover height and density obtained values, a linear regression model of water content dependence in the snow cover on the height above sea level has been built. The main calculation method for finding the linear equation coefficients is the least squares technique. The calculated values of the snow cover weight on 1 m2 earth surface of different coverage have been obtained. Its value at an altitude of 3500 m above sea level is 10,42 kPa at 2% coverage and 11.16 kPa at 1% coverage.
Highlights
The snow load on buildings and structures is created by the snow cover weight, the value of which is kgf/m2 numerically equal to water stock in millimeters
The snow load on the roof is formed under the influence of a number of additional factors, the mutual relationship and the calculated load of the snow cover during the design of various objects is calculated from the normative by multiplying the normative load by the coefficient (μ) transition from the weight of the ground snow cover to the snow load on the cover, which changes in accordance with the application B Code of Specification 20.13330.2016
Standard value of the snow cover weight Sg on 1 m2 horizontal earth surface is taken depending on the snow region for the territory of the Russian Federation
Summary
The snow load on buildings and structures is created by the snow cover weight, the value of which is kgf/m2 numerically equal to water stock in millimeters. Standard value of the snow cover weight Sg on 1 m2 horizontal earth surface is taken depending on the snow region for the territory of the Russian Federation. The values obtained in this case are in many cases significantly overestimated, and underestimated in poorly studied areas. These territories include the All-Russian all-season tourist and recreational complex «Elbrus», created on the southern slope of Elbrus.
