The dependence of DMF<inf>V</inf> on seismological parameters (magnitude, epicentral distance and soil type) is studied and is shown to be weak and insignificant for practical purposes. Simplified relation for computing DMF<inf>V</inf> as a function of the period is proposed irrespective of any seismological parameters.falseDamping modification factor | Vertical earthquake shakingConference Paper23662565655-66720232cpBook Series0
