Energy based procedures mainly consist of the prediction of earthquake input energy imposed on a structural system during an earthquake, and energy dissipation performance of the structure. The presented study focusses on the prediction of earthquake input energy. A large number of strong-ground motions have been collected from the NGA database, and parametric studies have been conducted for considering the effects of soil type, epicentral distance, moment magnitude and the fault type on input energy. Then prediction equations for input energy spectra, which are expressed in terms of the equivalent velocity (V eq ) spectra, are derived in terms of these parameters. Moreover, a scaling operation has been developed based on consistent relations between pseudo velocity (PS V ) and input energy spectra. When acceleration and accordingly velocity spectrum is available for a site from probabilistic seismic hazard analysis, it is possible to estimate the input energy spectrum by applying velocity scaling. Both of these approaches are found successful in predicting the V eq spectrum at a site, either from attenuation relations for the considered earthquake source, or from the results of probabilistic seismic hazard analysis conducted for the site.
