Abstract

This article introduces two engineering approaches to guide the simultaneous scaling of both amplitude and time of natural accelerograms. This with the objective of providing alternative tools to complement current data sets of earthquake records to be scaled and used for nonlinear time-history analysis. The first approach proposed for dual scaling relies on the explicit application of a ground motion prediction equation (GMPE) for spectral acceleration. The second approach makes use of a pair of GMPEs to estimate ground motion parameters (GMPs) defined in frequency/period and time domains. To characterize the intensity of the earthquake ground motion, the GMPs selected in this study are Arias Intensity and Housner Intensity.
