NONSTATIONARY MODELS OF SEISMIC GROUND ACCELERATION by Mircea Grigoriu1, Sonia E. Ruiz 2and Emilio Rosenblueth.3 J Technical Report NCEER. An extension of the Thomson's spectrum estimation method is used to adaptively estimate the evolutionary power spectral density (PSD) function of the target ground acceleration record.

Current estimates of seismic structural fragilities are commonly made on the basis of finite collections of actual or virtual ground-acceleration records that are scaled to have the same.
