ABSTRACT
For the last 10-15 years the changes of climatic conditions in the territory of Europe have been watching. The climatic changes have also tested at the territory of Ukraine. So the nature of operating snow load changes; precipitation becomes shortlived, but intensive. The increase of the snow load for short period in a number of cases results to failures of building structures. At the present time it is important to evaluate the reliability of existing buildings and to find out potentially dangerous groups of structures for their precise calculation. Hence it is necessary to get a model of a snow load with provision for all particularities of its stochastic nature. It is necessary also to develop the general strategy of evaluation of structure reliability under the action of a snow load. This work continues the snow probabilistic investigations which were exposed during the 4-th International Conference on SNOW ENGINEERING, Trondheim, Norway, June 19-22, 2000 (Pichugin 2000).
