Effect of surface layer stochasticity on seismic ground motion coherence and strain estimates
The significance of stochasticity in the characteristics of the surface layers of a site to the resulting spatial variation of seismic ground motions and the seismic ground strains is investigated. For this purpose, an analytical site-specific model is developed. The model approximates the site topography by a horizontally extended layer with random characteristics overlying a half-space (bedro...
متن کاملEstimation of signal characteristics in seismic ground motions
In this study it is investigated whether signal processing techniques and leastsquare minimization methods applied to seismic data can identify the deterministic signal components that contribute significantly to the motions. The identification of these deterministic components would then allow the treatment of the remaining part of the time histories as random and result in better descriptions...
متن کاملInfluence of Ground Motion Duration on the Structural Response at Multiple Seismic Intensity Levels
This paper aims to investigate the effects of motion duration on the structural seismic demands, seeking potential correlations between motion durations and structural responses at several seismic intensity levels. Three seismic intensity levels with 100years, 475years, and 2475years earthquake return periods (RPs) are first considered for correlation computations. Spectrally matched ground mot...
متن کاملProbabilistic Seismic Hazard Deaggregation of Ground Motion Prediction Models
Probabilistic seismic hazard analysis (PSHA) combines the probabilities of all earthquake scenarios with different magnitudes and distances with predictions of resulting ground motion intensity, in order to compute seismic hazard at a site. PSHA also incorporates uncertainties in ground motion predictions, by considering multiple Ground Motion Prediction ("attenuation") Models (GMPMs). Current ...
متن کاملEffect of Scarp Topography on Seismic Ground Motion
Abstract—Local irregular topography has a great impact on earthquake ground motion. For scarp topography, using numerical simulation method, the influence extent and scope of the scarp terrain on scarp's upside and downside ground motion are discussed in case of different vertical incident SV waves. The results show that: (1) The amplification factor of scarp's upside region is greater than tha...
