ABSTRACT. With the aim to contribute to the discussion on the validation of European and Italian design building code spectra, this paper describes and discusses the results obtained by means of equivalent linear analyses performed in a number of well documented test sites located alongside the Adriatic coast, in the town of Senigallia, Central Italy. Given the medium intensity shaking expected in the area (peak ground acceleration of 0.20g at ‘rock-like’ formation with a return period of 475 years) and the likely strain levels that can be induced on soils, and also given the geomorphologic characteristics of the site (mainly consisting of a Plio-Pleistocene clayey-marly bedrock underlying Quaternary plain deposits and alluvial terraces where 2-D effects appear to be not influent) a 1-D linear equivalent model was employed for seismic site response evaluation. The seismic response analyses were performed on eight different soil profiles where dynamic soil properties were accurately measured. In order to reduce the input seismic ground motions uncertainties Both real selected acceleration time histories and simulated accelerograms obtained by a seismic wave propagation model were assumed in the analyses,. The obtained results are synthesised in this paper and the elastic response spectra obtained at ground surface are compared with those provided by Eurocode 8 for the corresponding ground types. The practical significance, implications and applications of the spectra obtained with respect to the relevant prescriptions of the recently established Italian building codes for seismic areas are also discussed.

ABSTRACT. With the aim to contribute to the discussion on the validation of European and Italian design building code spectra, this paper describes and discusses the results obtained by means of equivalent linear analyses performed in a number of well documented test sites located alongside the Adriatic coast, in the town of Senigallia, Central Italy. Given the medium intensity shaking expected in the area (peak ground acceleration of 0.20g at ‘rock-like’ formation with a return period of 475 years) and the likely strain levels that can be induced on soils, and also given the geomorphologic characteristics of the site (mainly consisting of a Plio-Pleistocene clayey-marly bedrock underlying Quaternary plain deposits and alluvial terraces where 2-D effects appear to be not influent) a 1-D linear equivalent model was employed for seismic site response evaluation. The seismic response analyses were performed on eight different soil profiles where dynamic soil properties were accurately measured. In order to reduce the input seismic ground motions uncertainties Both real selected acceleration time histories and simulated accelerograms obtained by a seismic wave propagation model were assumed in the analyses,. The obtained results are synthesised in this paper and the elastic response spectra obtained at ground surface are compared with those provided by Eurocode 8 for the corresponding ground types.
