摘要: A versatile, nonstationary stochastic ground-motion model accounting for the time variation of both intensity and frequency content typical real earthquake ground motions is formulated validated. An extension Thomson's spectrum estimation method used to adaptively estimate evolutionary power spectral density (PSD) function target acceleration record. The parameters this continuous-time, analytical, are determined by least-square fitting analytical PSD estimated. As application examples, proposed applied two actual records. In each case, validation obtained comparing second-order statistics several traditional probabilistic linear-elastic response spectra simulated using with their deterministic counterparts characterizing
