A case-study (the saint nicolo cathedral) for dynamic characterization of soil from in situ and laboratory tests

摘要

The Saint Nicolo Cathedral of Noto was damaged by a post-seismic structural collapse on March 13th 1996 and is now under repair and restoration. The city of Noto is located near siracusa on the east coast of Sicitly and acttually is object of a seismic microzonation (level II) study. Assessment of the seismic risk of saint Nicolo Cathedral by means of analytical computation is also under way. To this end, in situ and laboratory investigations have been carried out in order to determine the soil profile with special attention being padi to the variation of shear modulus and damping ratio with dpeth. This paper is aimed at provding information about the Saint Nicolo Cathedral site characterisation for seismic analysis.
