Three levels of assessment of indicators of structural strength, reliability and durability of welded metal structures are considered for the construction of a system for managing the integrity of welded metal structures. Level 1 uses the criteria of the limit state of welded metal structures based on safety margin factors and is implemented by us using a failure assessment diagram. Level 2 of probabilistic analysis of safety and reliability involves the formulation and evaluation of the values of probabilistic indicators used to assess the structural strength, reliability and durability of welded metal structures in the presence of uncertainty and lack of completeness of input data. For level 3 of the risk analysis of the operation of welded metal structures, an algorithm for its implementation is proposed and an implementation option in the form of an integrity management system is prescribed. The failure assessment diagram of damage assessment is the basis of the implementation of all three levels. 14 Ref., 6 Fig. [ABSTRACT FROM AUTHOR]
