Tolstyakov R. Normalization of building steel structures corrosion resistance indices on the basis of expert systems

The problems of description of working environments corrosion attacks as structure additional fictitious loads and account of them in designing for corrosion resistance according to limit states has been examined. The mathematical model of reliability factor for normalization of construction steels corrosion resistance indices taking into account the nature of corrosion failure has been proposed. The obtained results of numerical simulation enabled to substantiate the variation of the limits of ranges of severity of corrosion attacks on building metal structures. The principles of construction of the expert system and its structure has been formulated. The results have been introduced into the normative documentation and in the processes of certification and diagnostics.
