Abstract: A Permanent Wireless Dynamic Monitoring System for the Colosseum in Rome

Return to previous page

By Giorgio Monti, Sapienza University of Rome, Italy

A key point for cultural heritage protection in many modern cities is to prevent damaging of historical monuments from urbanization disturbances, such as road and subway traffic vibrations. A typical dilemma is whether to focus on the effects of short-term vibrations due to construction activities or on the consequences of long-term traffic-induced vibrations. Both cases present practical difficulties in both monitoring and data analysis procedures. Besides, specific standards do not provide indications neither on how to extract meaningful features from data, nor on how to identify proper strategic decisions for an effective maintenance of monuments.

In this paper, an example of state-of-the-art monitoring system is presented with its application to the continuous trigger-free dynamic monitoring of the Flavian Amphitheater, widely known as the Colosseum, in Rome, Italy. The installation of the monitoring system, composed of wireless accelerometers located on the top portion of the North façade of the Monument, has allowed to study all the features of recorded vibrations, beyond the usually considered peaks. The system architecture, the wireless protocol and the processing of the data are described in detail in this paper. A discussion on the data collected during a full year of monitoring is presented, with focus on statistical representations of the dynamic response, such as fractiles of the peak accelerations, which are meaningful and synthetic indicators of the effects induced on the Monument by external actions of both natural and man-made nature.

Author Bio

Giorgio Monti was born in Roma, Italy, in 1961. He has graduated in Civil Engineering in 1986 at the University of Roma La Sapienza, then he has obtained a Master of Science at the University of California at Berkeley in 1993, and a PhD at the University of Roma La Sapienza in 1994 in Structural Engineering.

Since 2001 he has been Full Professor at the Sapienza University of Roma and visiting professor at the University of California at Davis, USA, and at the Hunan University and the Technical University of Nanjing, China. At Sapienza University he is the Director of the Master Course on “Advanced Structural Design according to Eurocodes”.

He is currently Associate Editor of the ASCE Journal of Structural Engineering.

He is Expert Member of the Ministry of Infrastructures and Transportations of Italy and serves in several EU pre-normative Committees. Since 2005 he has been National Coordinator of a Civil Protection program in Italy on “Assessment and Risk Reduction of Reinforced Concrete Buildings”.

His scientific activity addresses the topics of: modeling and analysis of reinforced concrete structures under seismic excitation, risk assessment of existing structures in reinforced concrete and masonry, reliability analysis of structures and infrastructures in seismic zones and code calibration, use of sustainable materials and dry prefabrication in constructions, strategies for seismic protection of buildings, including base isolation, strategies for the preservation of cultural heritage, advanced solutions and techniques for structural strengthening.

In these fields, he has so far produced more than 320 publications, of which more than 70 in peer-reviewed international journals, and 6 books.
