Probabilistic and Semi-probabilistic Analyses of Bridge Structures - Multi-level Modelling Based Assessment of Existing Structures
Performance and lifetime assessment of new and existing structures is a complex multidisciplinary topic that has been developed and intensively discussed for many years. Performance assessment requires a reference model as it can be provided by an analytical model or a numerical model like the finite element models. Such numerical models also allow the determination of the existing safety or reliability as well as the critical analysis of safety formats.
However, it should also be noted that there are different levels of modelling, from linear to non-linear, from system to detailed model formation. Based on a linear finite element model assessment, the aim of this paper is to determine the reliability level (reliability index) and the global safety factors using existing safety formats, like the ECOV format and the GSF format for non-linear finite element analyses. In addition, the effects of different system limits of NFLEMs on the reliability and safety are discussed.
