Vibration analysis and dynamic characterization of the Colosseum

Extensive measurements of the dynamic response of the Colosseum induced by road traffic were performed. The vibration level was evaluated in accordance with international standards to investigate the potential for structural damage. Using only the response, the natural frequencies and mode shapes of the monument were determined and compared with numerical ones, which were obtained by a finite element model. The mechanical properties of the model were updated in order to adapt the analytical response to the experimental one. Details of the test methods, measurements and analysis procedures and the major findings of the investigation are presented. Copyright © 2008 John Wiley & Sons, Ltd.
