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 ...

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 ...

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.

Design Ground Motion Library: An Interactive Tool for Selecting Earthquake Ground Motions [PDF]
Earthquake Spectra, 2015 The Design Ground Motion Library (DGML) is an interactive tool for selecting earthquake ground motion time histories based on contemporary knowledge and engineering practice. It was created from a ground motion database that consists of 3,182 records from shallow crustal earthquakes in active tectonic regions rotated to fault-normal and fault-parallel

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 ...

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.

Stochastic Ground Motion Simulation
2014Strong earthquake ground motion records are fundamental in engineering applications. Ground motion time series are used in ▶ response-history dynamic analysis of structural or geotechnical systems. In such analysis, the validity of predicted responses depends on the validity of the input excitations.
