GNGTS 2018 S essione 2.2 401 on the basis of this work, NDSHA synthetic accelerograms seems to be a promising tool to estimate site specific seismic hazard and, consequently, to perform time history analysis with site specific input or for the selection of accelerograms compatible with any target response spectrum. Further testing are needed in order to generalize these results and take into account the cumulative non-linear structural demand.
