DOI: 10.1007/s00024-019-02153-z
Abstract: We present an objective technique for assessing the fundamental resonance frequency ($${\text{f}}_{0}$$f0) of a given site through horizontal-to-vertical (H/V) spectral ratio. H/V spectral ratios have been determined from 5%-damped spectral acceleration derived from strong-motion time… read more here.
