On service life quantification and service life management
(2024) 2nd FABRE Conference on Existing Bridges, Viaducts and Tunnels: Research, Innovation and Applications, FABRE 2024 In Procedia Structural Integrity 62. p.259-267- Abstract
The service life of infrastructures is of high relevance for the provision of societal and industrial functionality and sustainability. Despite this high relevance, the service life is not explicitly considered of the design and operation procedures. Towards an efficient and sustainable service life management, this paper contains a description of approaches for service life limit quantification and service life management. The service life limit quantification is based on scenario modelling for identifying technical and economical service life limits. The technical service life limit is determined with a system reliability analysis and the comparison with target reliabilities accounting for human safety requirements. The service life... (More)
The service life of infrastructures is of high relevance for the provision of societal and industrial functionality and sustainability. Despite this high relevance, the service life is not explicitly considered of the design and operation procedures. Towards an efficient and sustainable service life management, this paper contains a description of approaches for service life limit quantification and service life management. The service life limit quantification is based on scenario modelling for identifying technical and economical service life limits. The technical service life limit is determined with a system reliability analysis and the comparison with target reliabilities accounting for human safety requirements. The service life management approach builds upon the service life limit quantification and further includes the probabilities, benefits, cost and consequences associated to the system states throughout the service life. In this way, technical, economic and life safety models and boundaries can be jointly analysed and optimised based on decision theory. Both the technical service life quantification and the service life management approaches are exemplified through the documentation of case studies. Furthermore, the principles and key outcomes pertaining to service life quantification are summarized.
