1 Introduction
-
Definition of a performance objective that describes a level of performance which is associated with a specific seismic hazard
-
Estimation of seismic demands on the system and its components through detailed structural analysis (preferably nonlinear)
-
Evaluation of the performance (at the system and component level) to verify that the performance objective has been met.
