EXPERIMENTAL STUDY OF SNOW LOAD DISTRIBUTION ON A SHELL OF THE GRAND SPORTS ARENA OF LUZHNIKI OLYMPIC COMPLEX

Introduction. The mechanism of the formation snow deposits on shell Luzhniki GSA and their redistribution in winter were established basis data obtained during monitoring load for over 20 years. Aim. In this article, distribution determined, along with numerical values form factor μ characterizing transition from ground to shell. Materials methods. measurements density carried out 1998 2019. results compared parallel (GSL) Luzhniki. addition, load, as well statistical analysis maximum annual GSL, analyzed using hydrometeorological decadic surveys Moscow, performed by V.A. Mikhelson Meteorological Observatory following dates field measurements. graphs repeatability wind directions month preceding observation plotted. Results. each section obtained. areas characterized increased deposition various periods accumulation andthe dependence speeds revealed. Graphs depicting surface years It was that loads period generally lay within design values, except local zones near internal contour installation canopy. Conclusion. shown formation, accumulation, comprise a complex uneven process, varying winter. When selecting analytical models calculating unique load-bearing structures, it is necessary account most unfavorable flow directions, at which an pattern occurs, physical properties observations.
