The paper describes the conditions for ensuring quality performance and reliability of the corrosion protection methods on the basis of the developed method to determine the corrosion resistance control parameters. Settlement and experimental evaluation of performance durability of protective coatings is made on the basis of physical and chemical effects modeling in the process of accelerated tests of samples with coatings designed for long-term protection against corrosion. Permissible deflection of performance structural elements are taken into account by safety factors of corrosion protection, depending on the category of responsibility. There were defined the requirements for performance durability with specified service life of structures and the degree of aggressiveness of the environment impacts. Parameters of structural and technological measures of primary and secondary protection are characterized by complex refractive maintainability of the coefficient of readiness. Determination of design parameters of structure durability was made in accordance with the established procedure of accounting reliability and readiness factors of corrosion protection established by the results of experimental studies. The studies allow an assessment of methods conformity of corrosion protection on the basis of values defining the parameters of corrosion resistance. The prerequisites for constructive regulation corrosion protection of steel building structures was created, also the procedure for the scientific and technical support for the selection of parameters on the level of corrosion hazard was defined on the basis of the design specification of primary and secondary measures of protection against corrosion. The characteristics of corrosion resistance, durability, maintainability of structures and protective coatings. The practical implementation of methodological approach was implemented during monitoring of the building steel structure state of the mining and metallurgical complex on the basis of the corrosion danger. The list of examined buildings includes construction of conveyor galleries, bridges and overpasses technology, pipe supports, constructional, sheet steel.
