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 ...

Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008
The current state-of-the-art ground motion models for application to the United States is summarized. The recent NGA ground motion models for shallow crustal earthquakes are in much more advanced than the currently available models for subduction earthquakes and for stable continental regions.

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 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 ...

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 ...

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.

Amplification of Earthquake Ground Motions by Surface Ground
2019This chapter introduces the amplification of seismic ground motion by surface ground. A calculation method for the amplification magnification of the acceleration due to surface grounds \( G_{s} \) is presented and a concrete calculation example is shown.
