Numerical Treatment of Seismic Accelerograms and of Inelastic Seismic Structural Responses Using Harmonic Wavelets
The harmonic wavelet transform is employed to analyze various kinds of nonstationary signals common in aseismic design. The effectiveness of the harmonic wavelets for capturing the temporal evolution of the frequency content of strong ground motions is demonstrated. In this regard, a detailed study of important earthquake accelerograms is undertaken and smooth joint time-frequency spectra are p...
متن کاملsource parameters of the 26 april 2007 bam earthquake obtained by the near field accelerograms data
on 26 december 2003 at 05:26lt (01:26gmt), a catastrophic earthquake mw 6.6, seismic moment (6 – 9 ×10 nm) struck the city of bam in the kerman province of southeast iran. the intense shaking in the city caused the complete collapse of nearly every building in the central parts of the city including many of the newer buildings, killing about 40000 people officially. the city lies to the east of...
متن کاملGeneration of spectrum - compatible accelerograms using information theory
The research addressed here is devoted to the generation of seismic accelerograms compatible with a given response spectrum and other associated properties. The time sampling of the stochastic accelerogram yields a time series represented by a random vector in high stochastic dimension. The probability density function (pdf) of this random vector is constructed using the Maximum Entropy (MaxEnt...
