ABSTRACT
Incremental dynamic analysis (IDA) (Vamvatsikos & Cornell 2002) has been a well-established methodology in earthquake engineering for assessing the performance of structural systems under a suite of ground motion records, each scaled to several levels of seismic intensity. Nevertheless, the need for performing nonlinear dynamic analyses both for various excitation magnitudes and for a large number of seismic records renders the IDA methodology a computationally highly demanding task potentially (Vamvatsikos 2013).
