Artificial ground motion compatible with specified peak velocity and target spectrum
Acta Seismologica Sinica, 2006In this paper, a method, which synthesizes the artificial ground motion compatible with the specified peak velocity as well as the target acceleration response spectrum, was proposed. In this method, firstly, an initial acceleration time history a g (0) (t), which satisfies the ...

Peak Ground Velocity Sensitive Deformation Demands and a Rapid Damage Assessment Approach
, 2003 The effect of peak ground velocity (PCV) on the maximum inelastic deformation demand of simple, non-degrading structural systems is studied. Ground motion data sets are assembled for pre-defined ranges of PCV and they are used to conduct nonlinear response history analysis of single-degree-of-freedom (SDOF) systems.

Soil Dynamics and Earthquake Engineering, 2002
Abstract It is recognized that soil improvement techniques are not economically feasible for mitigation of liquefaction-induced lifeline damages because of the large areas served. Instead, it is more practical to execute an emergency action immediately after an earthquake in order to prevent or minimize possible lifeline failures caused by the soil ...

On the Calculation of Peak Ground Velocity for Seismic Performance Assessment
Earthquake Spectra, 2015Ratios of pseudo‐spectral velocity (averaged over the period range of 0.5–2 seconds and at a period of 1 second) to peak ground velocity (PGV) were computed for hundreds of ground motion records selected from the PEER NGA Strong Motion Database. Two‐stage regression analyses were performed to develop models for the ratios.

Conditional Ground-Motion Model for Peak Ground Velocity for Active Crustal Regions
PEER Reports, 2020Conditional models for the horizontal and vertical peak ground velocity (PGV), given the pseudospectral acceleration [PSA(T)] values, are developed for active crustal regions. The period of the PSA(T) used in the conditional model, TPGV , is magnitude dependent, which captures the effect of the magnitude dependence of the earthquake source corner ...

Relationship between Peak Ground Acceleration, Peak Ground Velocity, and Intensity in Taiwan
Bulletin of the Seismological Society of America, 2003Based on the strong-motion data set from the 1999 Chi-Chi, Taiwan, earthquake and a shaking damage statistics database, we investigated the correlations between strong ground motions and earthquake damage (fatalities and building collapses) through a regression analysis.

During a disastrous earthquake, the early assessment and timely reporting of the peak ground acceleration (PGA) and peak ground velocity (PGV) maps will be crucial in an effective emergency response operation. In this study, we first derive an empirical relationship between M L and M W.

A Naive Bayes Classifier for Intensities Using Peak Ground Velocity and Acceleration
Bulletin of the Seismological Society of America, 2010Abstract A naive Bayes classifier is determined to predict intensities from peak ground velocity and acceleration. It is trained on the same dataset that was used in the study of Faenza and Michelini (2010). The naive Bayes classifier directly estimates a discrete probability distribution for the ordinal intensities.
