МЕТОДИЧЕСКИЙ ПОДХОД К ОБЕСПЕЧЕНИЮ РАБОТОСПОСОБНОСТИ МЕТАЛЛОКОНСТРУКЦИЙ В УСЛОВИЯХ КОРРОЗИОННОЙ ОПАСНОСТИ

Abstract

The process has been analyzed of monitoring of structure and installation process safety under corrosion hazard of building facilities. A high level of wear and service limits of structures of buildings and installations are the real threat, which increases probability of a loss. The principles are analyzed of assurance of process safety of structures and installations as an integral structural component of the enterprise safety. It is shown that the development of measures of the reliability assurance program comprises the qualimetric monitoring and risk diagnostics of the determining parameters of structural corrosion state. As used here, a methodology is proposed for assessing serviceability of corrosive structures taking into account the requirements of the process approach to quality and safety management based on the principles of DMAIC (Define, Measure, Analyze, Improve and Control). Classified are the signs of serviceability based on the safety class of systems of structure corrosion protection to justify efficiency of measures for structure maintenance based on their actual state. Methods are theoretically and experimentally justified of redundancy of means of primary and secondary corrosion protection of structural steel. A practical example is presented of setting and solving the direct and inverse problems of the design calculation of structure survivability under corrosion hazard.
