A monitoring system has been installed on the David by Michelangelo at the Galleria dell’Accademia in Florence, in order to monitor the possible evolution of the cracking pattern present in the tree trunk lying flat to the right leg and in the left ankle of the famous statue. Other parameters as vibrations and inclinations are monitored too. The system is based on a innovative device and on minimally invasive sensors as fiber optic Bragg gratings. The monitoring activity is ongoing. The first results, even in the absence of seismic events, have shown high sensitivity to vibrations and temperature variations.

Abstract
A monitoring system has been installed on the David by Michelangelo at the Galleria dell’Accademia in Florence, in order to monitor the possible evolution of the cracking pattern present in the tree trunk lying flat to the right leg and in the left ankle of the famous statue. Other parameters as vibrations and inclinations are monitored too. The system is based on a innovative device and on minimally invasive sensors as fiber optic Bragg gratings. The monitoring activity is ongoing. The first results, even in the absence of seismic events, have shown high sensitivity to vibrations and temperature variations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
