The issues of ensuring long-term reliable operation of building structures and creating conditions for environmental safety with the exclusion or minimization of negative impact on the environment due to failures are considered. Measures to overhaul the station for neutralization of acidic and alkaline industrial liquids ‒ an object of increased environmental hazard, taking into account the existing defects and damage are presented. The calculation of the bearing capacity of the most damaged reinforced concrete members of the structural system is performed using the extreme properties of concrete strains and the variational method in the theory of plasticity. The stain diagram of compressed concrete, which is limited by the point of maximum strain energy, is given. The dependences for determining the parameters of the dangerous normal cross-section of structures during bending on the characteristics of the compressive strength of concrete, which is established by the results of non-destructive testing are obtained. The dependences specified in the theory of plasticity of dependence for strength definition of reinforced concrete elements in an inclined section are resulted. When developing measures to protect structures, aggressive influences are taken into account. For protection against moisture and action on reinforced concrete designs of the aggressive environment waterproofing of penetrating action and elastic water-resistant two-component and chemically resistant polymers are applied.
