Ground motion prediction equations based on shallow crustal earthquakes in Georgia and the surrounding Caucasus

Earthquake Science, 2022
Strong ground motions caused by earthquakes with magnitudes ranging from 3.5 to 6.9 and hypocentral distances of up to 300 km were recorded by local broadband stations and three-component accelerograms within Georgia’s enhanced digital seismic network ...

Use of Fourier phase characteristics and effective stress analyses for post-earthquake ground motion estimation: application to ESG6 blind prediction steps 2&3 dataset and JMA accelerometric data

Earth, Planets and Space, 2023
After the occurrence of a large earthquake, engineering seismologists are often requested to estimate strong ground motions at a site where strong motion data were not obtained.

Shaking Table Test of a Base-Isolated Frame Structure under Near-Fault Ground Motions

Buildings, 2022
A five-story moment frame structural model with a base isolation system was tested on a shaking table. The isolation system comprised both linear natural rubber bearing (LNR) and nonlinear viscous dampers (NLVDs).

Equations for the estimation of strong ground motions from shallow crustal earthquakes using data from Europe and the Middle East : vertical peak ground acceleration and spectral acceleration [PDF]

, 2005
This article presents equations for the estimation of vertical strong ground motions caused by shallow crustal earthquakes with magnitudes M w 5 and distance to the surface projection of the fault less than 100km. These equations were derived by weighted

Strong Ground Motion Estimation [PDF]

, 2012
This progressive sequence of ground motion surprises suggests that the current state ofknowledge in strong motion seismology is probably not adequate to make unequivocal strong ground motion predictions. However, with these caveats in mind, strong ground motion estimation provides substantial value by reducing risks associated with earthquakes and ...

Comparison of wind turbine tower failure modes under seismic and wind loads [PDF]

, 2019
This paper studies the structural responses and failure modes of a 1.5-MW horizontal-axis wind turbine under strong ground motions and wind loading. Ground motions were selected and scaled to match the two design response spectra given by the seismic ...

Analysis of strong ground motions to evaluate regional attenuation relationships

Annals of Geophysics, 2002
Italian attenuation relationships at regional scale have been refined using a data set of 322 horizontal components of strong ground motions recorded mainly during the 1997-1998 Umbria-Marche, Central Italy, earthquake sequence.

Seismic reliability assessment of classical columns subjected to near-fault ground motions [PDF]

, 2013
A methodology for the performance-based seismic risk assessment of classical columns is presented. Despite their apparent instability, classical columns are, in general, earthquake resistant, as proven from the fact that many classical monuments have ...

A robust sagittal plane hexapedal running model with serial elastic actuation and simple periodic feedforward control [PDF]

, 2013
In this article we present a sagittal plane, sprawled posture hexapedal running model with distributed body inertia, massless legs and serial elastic actuation at the hips as well as along the telescoping legs.
