Structural reliability in the continuous feedback process for model validation and regulations improvement

Abstract

The connections between structural reliability and system reliability are reviewed, emphasizing their intimate dependence. The problem of model validation is then outlined; the importance of data in this respect is analyzed. The role of structural reliability in the set-up of regulations and standards is shown to be the statistical analysis of the ‘safety margin’ provided by component design. Furthermore the importance is stressed of implementing a continuous feedback between analysis and operational data on individual structures in order to improve and update prior estimates and models.
