Influence of Roof Shape on Snow Accumulation

[摘要] The paper describes the snow accumulation issues on the buildings and structures covers. The main factors influencing the nature of the snow load formation on random shape coverings are revealed. The holding capacity dependence of incoherent snow on the coating configuration and the snow friction coefficient on the roof surface is established. The individual factors influence degree on the snow accumulation nature is revealed. An analytical dependence of the snow capacity to be retained on the coating surface from the roof outline and the snow adhesion forces on the coating material surface is proposed. Recommendations for taking into account the coating structures outline in the buildings and structures design allowing to clarify the snow accumulation features that are characteristic of this roof shape are given. The dependence in the parametric shape of the cover inclination critical angle from the magnitude of the snow friction coefficient on the roof surface is established. The obtained results allow clarifying the snow load for incoherent snow depending on the friction coefficient magnitude.
