Finite element modeling, calculation and analysis of metal cylindrical mesh shells are carried out. The choice of the surface topology is justified and the recommended ratios of overall dimensions are adopted. The criteria for determining the stability of the grid are given. The limits of permissible curvature and the main geometric parameters are obtained. The effect of increasing the rigidity and height of the structure on the work of the mesh surface is analyzed. Patterns of changes in nodal deviations and internal force factors of vulnerable areas of the shell are revealed. The results of changes in the shape and features of the critical deformation of the system are presented.
