A METHODOLOGY TO ANALYZE THE AMBIENT VIBRATIONS IN THE COLOSSEUM

For the dynamic soil Colosseum interaction, subjected to ambient vibrations, we propose a methodology which collects three models used with success in the disciplines Geophysics, Structural and Transportation Engineering. The trains’ transit produces the vibrations in our global model. Firstly, we use such vibrations to identify the map of elastic modules, in elevation by the modal analysis, in the foundations and soil by the diagrams H/V. Finally, this methodology solves the unique problem of the linear elastic behaviour of the monument subjected to different dynamic actions.
