Elastoplastic and time-dependent analysis of seismic structures has become a major analysis technique in popularly accepted performance-based seismic design. However the primary difficulty in using this technique is the lack of a unified criterion in the selection of various intensity indices of ground motions. Various earthquake factors influencing the elastoplastic response of seismic structures are highly sophisticating. Hence it is vitally important to choose an appropriate and comprehensive earthquake intensity index to correlate well to a structural performance. In this study, a total of 30 earthquake intensity indices published in the literature are reviewed and are evaluated through correlation analysis based on 60 ground motion records. Examined herein is the correlation between existing earthquake intensity indices and the seismic responses of elastoplastic SDOF and MDOF systems. The characteristics and applicability of such indices are also discussed in some details, based on which appropriate earthquake intensity indices are recommended.
