Damping modification factors for acceleration response spectra
Geodesy and Geodynamics, 2017 DMF (Damping modification factors) are used to modify elastic response spectral values corresponding to damping ratio 5% to other damping levels. The influence of seismological parameters (magnitude, epicentral distances and site conditions) on DMF for acceleration spectra was analysed.
