Abstract. The developed design of the mesh shell has the ability to fold by decreasing its dimensions in one direction and increasing in the other. The fundamental difference of this design is the feasibility of folding the dome exactly wholly without the need for a complete separation of the shell into separate elements. The presented step-by-step description of actions in the general method of constructing the shell surface makes it possible to model the skeleton of a folded mesh dome. Recommendations for calculating the design include a description of the methods used to perform calculations manually, the derivation of arguments in favor of computer calculation, the instructions for creating a model, the definition of rigidity and types of finite elements, as well as accounting for nonlinearity in the design of the dome in the software LIRA-CAD. The specification of the calculation scheme and the calculation itself are carried out using the general theory of shells. The area of practical implementation of the folding mesh dome is quite wide: it is the construction industry, defense production, agricultural sector, and the industry as a whole.
Key words: folding dome, mesh shell, surface construction, dome calculation, software complex. - REFERENCES
