Static calculation of the stability of the lenticular membrane-pneumatic coating of the structure

Abstract

The relevance of the topic developed by the authors of this article consists in the fact that lenticular pneumatic coatings of structures have shown high load-bearing capacity, but it manifests itself only when the coating, designed in accordance with the current norms of construction design of structures, does not lose stability from snow loads. The aim of the study is to develop a method for finding parameters and assigning a value of excess air pressure sufficient to ensure the stability of a nonlinear lenticular membrane- pneumatic coating of large spans under static loads. This article discusses a static calculation for the loss of stability of a lenticular membrane-pneumatic structure. The main works of other authors on this issue are presented, the research method used by the authors of the article is described in detail. The obtained research results are described in detail and their comparison with the results of other authors is given. In conclusion, the main conclusions based on the results of this study are given.
