The article is devoted to the development of a nodal joint for assessing the level of rigidity of a cylindrical mesh shell. Practical recommendations on the assembly of the tightening unit are proposed and the design of the screw coupling for the adjustable tension process is presented. The rational locations of the nodal joints on the lower belts of the support faces are determined. Numerical studies of possible schemes were carried out and the regularity of changes in the vertical movements of nodes from the end to the center was established. The positive contribution of reinforcing elements was revealed and the rigidity of the shell was determined. It is shown that the introduction of puffs with a developed node increases the level of resistance to operational loads and significantly reduces deformations in characteristic zones.
