In Situ and Laboratory Tests for Site Response Analysis in the Ancient City of Noto (Italy)

The city of Noto belongs to a seismic area located on the eastern zone of Sicily (Italy). The following in situ investigations were carried out in order to determine the soil geotechnical characteristics: Down Hole (DH) tests, Dilatometer tests (DMT), Multichannel Analysis of Surface Waves (MASW) and geotechnical borings. Moreover the following investigations in the laboratory were carried out on undisturbed samples: Resonant Column, monotonic compression loading Triaxial tests and Direct shear tests. Finally synthetic seismograms have been drawn at the bedrock with the aim to perform the ground response analysis at the surface, in terms of time history and response spectra, by a linear-equivalent model.
