F. Zareian I. Iervolino R.W. Graves C. Galasso 2012 The study presented in this paper is among the first in a series of studies toward the engineering validation of the hybrid broadband ground‐motion simulation methodology by Graves and Pitarka (2010). This paper provides a statistical comparison between seismic demands of single degree of freedom (SDoF) systems subjected to past events using simulations and actual recordings. A number of SDoF systems are selected considering the following: (1) 16 oscillation periods between 0.1 and 6 s; (2) elastic case and four nonlinearity levels, from mildly inelastic to severely inelastic systems; and (3) two hysteretic behaviors, in particular, nondegrading–nonevolutionary and degrading–evolutionary. Demand spectra are derived in terms of peak and cyclic response, as well as their statistics for four historical earthquakes: 1979 <i>M_w</i> 6.5 Imperial Valley, 1989 <i>M_w</i> 6.8 Loma Prieta, 1992 <i>M_w</i> 7.2 Landers, and 1994 <i>M_w</i> 6.7 Northridge. application/pdf 10.1785/0120120018 en Seismological Society of America Validation of ground-motion simulations for historical events using SDoF systems article
