The paper summarizes some results of the investigation performed since 2009 on the San Michele bridge (1889), one of the most important monuments of XIX century iron heritage. The diagnostic campaign aimed at the assessing the structural state of preservation includes preliminary dynamic testing, monitoring and FE model development and calibration. Within the ongoing Structural Health Monitoring of the bridge, the dependence of the dynamic characteristics (i.e. natural frequencies and mode shapes) on several parameters such as temperature and amplitude of the excitation, is addressed and discussed in the paper.

Abstract
The paper summarizes some results of the investigation performed since 2009 on the San Michele bridge (1889), one of the most important monuments of XIX century iron heritage. The diagnostic campaign aimed at the assessing the structural state of preservation includes preliminary dynamic testing, monitoring and FE model development and calibration. Within the ongoing Structural Health Monitoring of the bridge, the dependence of the dynamic characteristics (i.e. natural frequencies and mode shapes) on several parameters such as temperature and amplitude of the excitation, is addressed and discussed in the paper.File in questo prodotto:
