The article covers the influence of the snow cover on the behaviour of translucent roofs acting as envelope structures. The authors note that the influence of the snow cover accumulated on the surfaces of translucent roofs is the least favourable influence produced on these structures, as any cover deprives translucent structures of their principal function; that is, admitting the sunlight and providing the natural illumination of the under-roof space. One of the actions aimed at prevention of the snow accumulation on the surfaces of translucent roofs represents the right choice of glazing, mode of heating and the roofing inclination angle, so that the snow could melt away within hours after a snowfall. However, this method requires a thorough research of the snow melting process typical for translucent roofs.
The authors provide the field data and describe the experiments involving the accumulation and melting of the snow on the surface of the roof glazing, given different angles of inclination. On the basis of the above, the authors propose a snow melting model that is based on the dynamic behaviour of the snow cover in the course of melting. This model may be used to resolve a wide range of problems that consist in the identification of the time period while the snow cover may rest on translucent roofs of different inclination angles, as well as the identification of the maximal amount of snow accumulated on translucent roofs without melting.
Numerical methods were applied to identify the time periods in the course of which the snow cover retained on the glass roofs that had different inclination angles. The snow melting model developed by the authors was used for the above purpose.
