Seismic ground motion parameter relations

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1978
The relationships among spectral velocity for 0.5 hz and 1.0 hz frequencies, peak ground acceleration, and peak ground velocity of earthquake-induced ground motion are investigated using the horizontal components of motion from 70 California strong-motion records and accounting for event size, source-to-site distance, and geologic conditions at the ...

Strong ground motion of mine tremors: Some implications for near-source ground motion parameters

Bulletin of the Seismological Society of America, 1981
abstractGround acceleration was recorded at a depth of about 3 km in the East Rand Proprietary Mines, South Africa, for tremors with −1 ≦ ML ≦ 2.6 in the hypocentral distance range 50 m < R ≦ 1.6 km. The accelerograms typically had predominant frequencies of several hundred Hertz and peak accelerations, a, as high as 12 g. The peak accelerations

The Relation Between Ground Motion, Earthquake Source Parameters, and Attenuation: Implications for Source Parameter Inversion and Ground Motion Prediction Equations

Journal of Geophysical Research: Solid Earth, 2018
AbstractTheoretical equations relating the root‐mean‐square (rms) of the far‐field ground motions with earthquake source parameters and attenuation are derived for Brune's omega‐squared model that is subject to attenuation. This set of model‐based predictions paves the way for a completely new approach for earthquake source parameter inversion and ...

Parameters Observation of Spatial Variation Ground Motion

2009
The procedure of random vibration analysis of linear structure subjected to spatial variation ground motion was deduced. A linear continuous beam sub- jected to spatial variation ground motion was established; By using the Claugh- Penzien self power spectrum model and Harichandran-Vanmarcke coherence function model, the influences of distance between ...

A UNIFORM ESTIMATION OF SOME BASIC GROUND MOTION PARAMETERS

Journal of Earthquake Engineering, 1998
A dataset of 690 strong motion component records of horizontal accelerations are analysed to derive predictive relationships for Arias Intensity, duration and number of pulses as functions of acceleration level as well as their dependence on the magnitude and distance of the source. The relationships show that the records should follow the patterns set

Discussion on Ground Motion Parameters of JiYin Hydraulic Project

Applied Mechanics and Materials, 2013
JiYin hydraulic project is located at the branch of Keliya River, Yutian county of Xinjiang. During the stage of its planning and design, a magnitude 7.3 earthquake occurred 43km away from the southeast of the dam. As the earthquake was in the southeastern part of Altyn Tagh Fault which was recognized in the past as a low seismicity segment, the ...

Ground Motion Parameters Influences on Input Seismic Energy

Applied Mechanics and Materials, 2012
Based on the energy analysis of a multi-degree-of-freedom (MDOF) system, a mode decomposition method for the input seismic energy is proposed, which substitutes a MDOF system with equivalent single-degree-of-freedom (SDOF) systems. The input seismic energy is obtained, using the actual earthquake data.

Engineering Ground-Motion Parameters Attenuation Relationships for Greece

Bulletin of the Seismological Society of America, 2007
Engineering ground-motion parameters can be used to describe the dam- age potential of an earthquake. Some of them correlate well with several commonly used demand measures of structural performance, liquefaction, and seismic-slope stability. The importance of these parameters comes from the necessity of an alter- native measure to the earthquake ...

Ground motion prediction equations for higher order parameters

Soil Dynamics and Earthquake Engineering, 2019
Abstract Amplitude, duration and frequency content are the three key characteristics of a ground motion time history. Few ground motion parameters quantifies two and rarely three of these features. There are even fewer ground motion prediction equations (GMPEs) available for these ground motion parameters.
