Domain, occupied by structure, is divided into two subdomains (Fig. 3). The left subdomain is approximated by finite elements and the right subdomain is approximated by discrete-continual finite elements. Modulus of elasticity of material of structure is equal to 3000  E kN/cm 2 . Poisson ’s ratio of material of structure is equal to 0.16   . Some results of structural analysis are presented at Fig. 4-6. Acknowledgements The Reported study was funded by Government Program of the Russian Federation “Development of science and technology” (2013 -2020) within Program of Fundamental Researches of Ministry of Construction, Housing and Utilities of the Russian Federation and Russian Academy of Architecture and Construction Sciences, the Research Projects 7.1.1 and 7.1.2”.
