Abstract

The study suggests a method for determining the characteristic and desired values of corrosion resistance indicators to estimate the reliability parameters of systems of anticorrosive protection of structures (SAPS). The approach is based on developing robust (resistant to external influences) systems for designing measures of primary and secondary protection of metal structures against corrosion. Technological methods of diagnostics and maintenance are substantiated to improve the ways of using the constructions at all stages of their life cycle. Stronger corrosion resistance, that is, resistance to aggressive operating environments, is provided by effective methods of primary and secondary protection of metal structures from corrosion. The design is aimed at developing the provisions of the current standards of EN 1990 on the SAPS. It is established that the proposed requirements are aimed at ensuring the quality of metal structures and are achieved through calculations by the method of limit state design (LSD) using reliability coefficients (EN 1991). Robustness and durability are ensured in accordance with the provisions of EN 1993. The characteristic values of the quality indicators of protective coatings (EN ISO 12944, EN 1461) and structural material (EN 1993-1-4) are used. However, the procedures mean that such operating conditions are limited as for estimating the durability.

The proposed technique will improve the measures for anticorrosive protection of structures based on the robust design. The implementation of the method justifies the design and technological preparation of work to extend the durability of the structures. Effective procedures of primary and secondary protection have been introduced, and the requirements of the ISO 9001 international standards have been implemented
