AB - Empirical ground-motion prediction equations (GMPEs) require adjustmentto make them appropriate for site-specific scenarios. However, the process ofmaking such adjustments remains a challenge. This article presents a holistic frameworkfor the development of a response spectral GMPE that is easily adjustable todifferent seismological conditions and does not suffer from the practical problemsassociated with adjustments in the response spectral domain. The approach for developinga response spectral GMPE is unique, because it combines the predictions ofempirical models for the two model components that characterize the spectral andtemporal behavior of the ground motion. Essentially, as described in its initial formby Bora et al. (2014), the approach consists of an empirical model for the Fourieramplitude spectrum (FAS) and a model for the ground-motion duration. These twocomponents are combined within the random vibration theory framework to obtainpredictions of response spectral ordinates. In addition, FAS corresponding to individualacceleration records are extrapolated beyond the useable frequencies using thestochastic FAS model, obtained by inversion as described in Edwards and Fäh (2013a).To that end, a (oscillator) frequency-dependent duration model, consistent with theempirical FAS model, is also derived. This makes it possible to generate a responsespectral model that is easily adjustable to different sets of seismological parameters,such as the stress parameter Δσ, quality factor Q, and kappa κ0. The dataset used inBora et al. (2014), a subset of the RESORCE-2012 database, is considered for thepresent analysis. Based upon the range of the predictor variables in the selected dataset,the present response spectral GMPE should be considered applicable over the magnituderange of 4 ≤ Mw ≤ 7:6 at distances ≤200 km.
