This paper illustrates the results of site investigations carried out in the center of Macerata, a town of about 40,000 inhabitants located in the vast region struck by the 2016-2017 Central Italy seismic sequence. The site investigations were planned as part of a study for the assessment of the seismic vulnerability of two ancient buildings, property of the University of Macerata. The investigation program comprised boreholes to 40-100 m depth, Vs measurements by seismic dilatometer in backfilled boreholes to 40-100 m, down-hole tests to 40 m, surface wave tests and seismic noise measurements. Laboratory tests, including cyclic/dynamic tests, were carried out on undisturbed samples. The site characterization based on in-situ investigations and laboratory test results is described in the paper. The investigation data permitted to define the input geotechnical subsoil model and related parameters for a site response analysis aimed at evaluating the seismic action on the existing buildings.

Abstract

This paper illustrates the results of site investigations carried out in the center of Macerata, a town of about 40,000 inhabitants located in the vast region struck by the 2016-2017 Central Italy seismic sequence. The site investigations were planned as part of a study for the assessment of the seismic vulnerability of two ancient buildings, property of the University of Macerata. The investigation program comprised boreholes to 40-100 m depth, Vs measurements by seismic dilatometer in backfilled boreholes to 40-100 m, down-hole tests to 40 m, surface wave tests and seismic noise measurements. Laboratory tests, including cyclic/dynamic tests, were carried out on undisturbed samples. The site characterization based on in-situ investigations and laboratory test results is described in the paper. The investigation data permitted to define the input geotechnical subsoil model and related parameters for a site response analysis aimed at evaluating the seismic action on the existing buildings.
