Abstract
Three levels of assessment of indices of structural strength, reliability and durability of welded metal structures are considered for the construction of the integrity management system (IMS) 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 indices 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 realization is proposed and an implementation option in the form of an IMS is prescribed. The two-criteria failure assessment diagram is the basis of the implementation of all three levels.
Keywords: risk, failure probability, consequences, two-criteria approach, failure assessment diagram, probabilistic safety analysis, risk matrix, integrity management system
