ACCELERATION RESPONSE SPECTRA
Acceleration response spectra are computed from the convolution of the site spectral amplification (obtained by GIT) with the seismic input. Procedure follows the 'indirizzi e criteri per la microzonazione sismica (Gruppo di Lavoro MS, 2008).
SMOOTHED RESPONSE SPECTRA
Smoothed acceleration response spectra are obtained from the previous by a standard procedure of smoothing.
Spectral amplification is computed from the ratio of the site acceleration response spectra with the average seismic input response spectra and can be compared with the NTC08 curves of different ground types
