description: The subject of the graduate qualification work is Â«Calculation of a large-span structure with a cable net roof coating of double curvatureÂ». This work is devoted to the exploration of the stress and strain state of the double curvature roof coating along an orthogonal cable net and its supporting structures. During this work, a review of calculating theories for the effect of symmetrical and asymmetric loads on rigid and pliable supports was made for both individual flexible threads and threads as part of spatial structures. As a result of work, an analysis of the stress-strain state of the bearing structures of the coating, the support ring and spacer columns was performed. An empirical iterative method for determining the value of the pre-tension of non-shallow threads in the PC "Lira Soft" was suggested. Recommendations for the construction of finite element and information models of buildings and structures with hanging cable roof coatings have been developed. A comparative analysis of the obtained internal forces and deflections of a flexible thread, obtained as part of the calculation scheme of a spatial structure in the PC "Lira Soft" and by the analytical method in a flat formulation of the task, was carried out. Examples of constructing and calculating the main nodes of load-bearing structures in IDEA STATICA were implemented.
