In the study of the “behavior” of the bearing elements of mobile systems of various types in the process of their operation at the facilities of the FIFA World Cup 2018 in Kazan, a number of imperfections were identified that have a significant impact on their bearing capacity and deformability, namely, the influence of gaps in the flooring on the redistribution of efforts in the flooring and in the structure as a whole. The article deals with the influence of imperfections in the fastening of combined plywood-metal flooring as a horizontal disk of stiffness on the stress–strain state. The problem is solved in a geometrically and physical nonlinear formulation. A simple method of accounting for imperfections of flooring fastening is proposed. By considering different values of gaps between the flooring and the frame, their influence on the stress–strain state of the flooring and on the redistribution of stresses in the frame of the structure is estimated. To determine the redistribution of forces in the rods, the calculation was performed by the finite element method in the PC “Lira-SAPR.”
