Calculations of strength and stability are performed by the finite element method in the spatial formulation of the problem (volumetric calculation scheme) using the Compas 3d software. When carrying out our calculations, we are guided by the regulatory framework in the sphere of construction and architecture in Russia. All calculations are made in accordance with SNiP 2.01.07-85 -load and impact. We have also accumulated experience in the use of European normative documents on design.
