Nga-West2 Ground Motion Model for V/H Response Spectra
Abstract eng: A ground motion model (GMM) was developed for the vertical-to-horizontal (V/H) ratio of 5%-damped elastic response spectra at periods ranging from 0.01 to 10 sec. The V/H GMM includes equations for the median V/H ratio and for the aleatory within-event, between-event, and total standard deviations. The V/H model is based on the GMMs that we have developed for the vertical and “average” horizontal components of ground motion using a mathematical formation that accounts for the correlation between these two components. We validated the V/H model against the NGA-West2 empirical database. We consider our V/H model to be valid for worldwide shallow crustal earthquakes in active tectonic regions for moment magnitudes ranging from 3.3 to 8.5, depending on the style of faulting, and for site-to-source fault rupture distances ranging from 0 to 300 km. The V/H ratios predicted from the model show a strong dependence on spectral period and site response.
