Abstract

This paper deals with the climate loading of tensile surface structures. The approaches for the snow load calculation were summarized and a new usage for tensile surface structures based on established procedures has been proposed. The snow load distribution and accumulation were presented in the form of an algorithm implemented in finite element software. The results of the algorithm for snow load accumulation were verified on simple examples with vertical, inclined, and curved surfaces.
