Development of ground motion models compatible with ground motion prediction equations
2014One 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

Synthesis of Stochastic Representations of Ground Motions
Bell System Technical Journal, 1970In 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-

In Sect. 1.1, basic concepts and terms in “ground motion seismology” are defined. In Sect. 1.2, the fundamentals of “elastodynamics” are explained since “seismology” is built on a foundation of elastodynamics. The “equation of motion” and “wave equation” are then obtained for ground motion, and their nature as seismic waves with attenuation are ...

The availability of empirical strong ground motion data will always be less that what would be needed to meet the needs of a variety of ever demanding engineering problems. A set of strong ground motions, either recorded or theoretically simulated, is the necessary database for the civil engineering design, regarding both new construction and ...

The main objectives of this study are: (1) to choose the vertical ground motion models (GMMs) that are consistent with the magnitude, distance, depth, and site amplification scaling of the updated Turkish ground motion database, and (2) to combine the vertical GMMs with the V/H ratio models selected in the accompanying paper (Alipour et al.

Tuning of stochastic ground motion models for compatibility with ground motion prediction equations
Earthquake Engineering & Structural Dynamics, 2015SummaryStochastic ground motion models can facilitate a versatile description of earthquake acceleration time‐histories by modulating a white‐noise sequence through functions that address spectral and temporal properties of the excitation. This is established by relating the parameters of these functions to earthquake and site characteristics through ...

Ground Motion Induced by Train Passage
Journal of Engineering Mechanics, 2006Two methods are illustrated to effectively calculate the ground motion induced by constant speed moving loads. On the one hand, the dynamic Betti-Rayleigh reciprocity theorem allows one to take full advantage of the availability of Green's functions for a homogeneous or a horizontally layered half-space.

The Motion of the Ground in Earthquakes
Scientific American, 1977The slippage along a fault that produces an earthquake radiates seismic waves; the manner in which these waves shake the ground bears on the design of buildings and other structures in the earthquake zones. Since seismic waves span such a broad spectrum of period and amplitude, many different kinds of instruments and experimental techniques are needed ...
