Regional Ground-Motion Simulation Using Recorded Ground Motions
Bulletin of the Seismological Society of America, 2021ABSTRACT 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.

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.

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.

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 ...

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.

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 ...

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
