THE INFLUENCE OF RECORD SELECTION IN ASSESSING UNCERTAINTY OF FAILURE RATES

A growing attention is developing on the analysis of seismic reliability of structures. Usually the assessment is performed via non-linear dynamic analyses carried out on computer models and aimed at assessing failure rates associated with a set of possible performance levels. The present work aims to highlight how the process of record selection can significantly influence the final results, being a source of relevant uncertainty. A case study application is presented and results are critically discussed.
