Regional Ground-Motion Simulation Using Recorded Ground Motions

Bulletin of the Seismological Society of America, 2021
ABSTRACT Regional ground-motion simulation is important for postearthquake seismic damage assessment. Herein, a ground-motion simulation method using recorded ground motions is proposed. Inverse-distance-weighted interpolation of the response spectra is performed to obtain the response spectrum at the target location.

Ground Motion Characterization for Vertical Ground Motions in Turkey—Part 1: V/H Ratio Ground Motion Models

Pure and Applied Geophysics, 2019
Two approaches are used to develop the vertical design spectra in probabilistic seismic hazard assessment (PSHA): (i) performing PSHA for the vertical component using vertical ground motion models (GMMs), and (ii) utilizing the V/H ratio GMMs to scale the horizontal spectrum during or after the hazard calculations for the horizontal component.

Earthquake Ground Motions

Annual Review of Earth and Planetary Sciences, 1988
In this review, we discuss some of the many phenomena that can determine the nature of strong ground motion. Some of these phenomena have been inferred from the study of existing ground-motion records, and others are inferred from theoretical models of earthquake sources and wave propagation.

Synthesis of Stochastic Representations of Ground Motions

Bell System Technical Journal, 1970
In this paper, we study a number of stochastic models including stationary, nonstationary, and linear processes for the purpose of simulating earthquake- or explosion-induced ground motions. The important statistical characteristics of each model and their effects on structural systems are investigated in some detail. We obtain expressions for the mean-

Development of ground motion models compatible with ground motion prediction equations

2014
One of the most important aspects of seismic risk assessment is the characterization of the earthquake hazard through appropriate models that adequately address its variability for different seismicity levels. For applications involving dynamic analysis, especially in the context of performance based earthquake engineering, this requires description of
