The goal of the work at the given stage is to study the carrying capacity of members of antenna and feeder devices, oil reservoirs, tower industrial constructions, having various operation failures and technological defects. The research analytical and numerical methods are used. The results obtained: stressed-stained states and the carrying capacity of structural members for oil storage using the earlier developed TANK and RESERVOIR software are calculated; efficient strain diagrams for thin-wall circular structural members of antenna and feeder devices are built considering residual stresses by using the earlier developed RING software; a mathematical model of strain of a curve-linear rod is built considering geometrically nonlinear effects and defects of geometrical characteristics considering the effects of a real load history; the calculation efficiency of a project-iteration version of the finite-element method for calculating plate members of thin-wall structures is studied, and the accuracy of the obtained results is verified; the effects of defect parameters and the defect locations on the carrying capacity of a reinforced concrete plate are numerically analyzed.
