In this paper the probabilistic model of the snow accumulation on the roofs with height discontinuity was worked out, the decreasing coefficient for the snow load weight was received and the ways of their application in the designing were elaborated. The probabilistic model for impulse stochastic process of snowfall sequence was developed. Data from meteorological stations in Ukraine allow determination of statistical characteristics: average annual snowfall amount and exponential distribution of values of one snowfall. The law of intensity distribution of snow melting has been determined experimentally. The territorial zoning map of Ukraine by characteristic values of the snow load on the roofs that emanate heat was developed.
W pracy opracowano probablilistyczny model akumulacji śniegu przy zmianie wysokości dachu, otrzymano współczynnik zmniejszający dla obciążenia śniegiem oraz wypracowano sposoby jego wykorzystania w projektowaniu. Rozwinięto model probablistyczny dla impulsowego procesu stochastycznego dotyczącego opadu śniegu. Dane ze stacji meteorologicznych na Ukrainie pozwoliły określić charakterystyki statystyczne: średni roczny opad śniegu i wykładniczy rozkład wielkości w pojedynczym opadzie śniegu. Prawo rozkładu intensywności topnienia śniegu zostało określone eksperymentalnie. Rozwinięto mapę stref terytorialnych Ukrainy za pomocą charakterystycznych wielkości obciążenia śniegiem dachów wydzielających ciepło.
