Summary
:
This study presents a framework for successively improved structural analysis and verification. For structural analysis the initial level comprises beam, frame, handbook or simple FE models combined with local resistance models. The most enhanced level is a full non-linear FE-analysis reflecting all possible failure modes. The verification format is divided into partial safety factor format, global resistance safety factor format and full probabilistic analysis. To include bridge specific information is also treated. For the case study bride, the difference in permitted axel load was ten times higher for the most enhanced analysis compared with the initial one.
