The article defines the prerequisites and criteria for constructing rational shapes of cylindrical mesh shells. The correlations of geometric parameters, taking into account the overall dimensions in the arc direction, are revealed. The required number of nodal connections is installed at the attachment points along the contour and in the middle zone. The main provisions on the creation of geometric schemes for the formation of structures are formed and possible options for assigning dimensions are considered. The expediency of using identical cells in the framework of constructing a regular mesh surface structure is substantiated. The sequence of calculation of the parameters determining the shape of the structure has been developed.

In the article, as part of the study of the stability of circular spatial structures, the parameters of the critical state of cylindrical mesh shells are determined. The features of using a solid analog are analyzed and a dependence is obtained to determine the magnitude of the critical load. The influence of geometric parameters on the degree of vulnerability and the danger of curvature of the mesh surface has been established. A rational span value is found for a fixed length and a given radius of curvature. A computer simulation using square cells was carried out and possible forms of loss of stability of the shells were determined. An acceptable similarity has been obtained between the calculation results of solid and mesh surfaces.
