In this paper we describe an experimental study of materials properties on snow accreting. The experimental samples of the materials which are used usually for the outdoor are high polymer plate, polymer coated metal plate, metal plate and glass. Snow accreting property of various materials dominated delamination state and adfreezing strength of snow and ice to the materials. As a result of the experiment, it becomes clear that three factors such as heat capacity, contact angle and the surface roughness exert a significant influence on the snow accreting properties.

The present paper has shown the elastic buckling of a single layer latticed cylindrical roof under snow loading using a fully nonlinear finite element solution procedure and simple reduced stiffness analyses. The rigidly-jointed latticed roof consists of 212 straight members. Two types of boundary support system and four types of snow loading system have been adopted. The distributions of displacements and internal axial forces change due to the boundary conditions and the loading ones. It has been observed that nonlinear numerical experiments are very sensitive to geometric imperfections. A correlation between the scattered nonlinear buckling responses and the reduced stiffness lower bound load spectra, has been discussed.
