Seismic site classification from the horizontal-to-vertical response spectral ratios: use of the Spanish strong-motion database [PDF]

, 2019
Normally, the average of the horizontal-to-vertical (H/V) ratios of the 5% damped response spectra of ground motions is used to classify the site of strong-motion stations. In these cases, only the three-orthogonal as-recorded acceleration components are
