Integrated System for Continuous Dynamic Monitoring: "Ponte Nuovo Del Popolo" Bridge

Abstract : The Italian territory is characterized by a high seismic risk and the presence of several existing structures and infrastructures leads to the definition of accurate procedures and methodologies to evaluate their safety conditions and the life-cycle performance. In this framework Structural Health Monitoring (SHM) is currently more and more considered as a key activity to increase the knowledge on the structural behavior of existing bridges. The paper reports the on-site diagnostic investigations and the installation activities of a SHM system of the ÒPonte Nuovo del Popoloî bridge, located in the city center of Verona. The results of the first 1.5 year of monitoring are presented, analysing the operational conditions of the structure subjected to both static and dynamic loads. Specific algorithms and processing software were developed and implemented to perform the continuous real time treatment and analysis of static data and the automated extraction of modal parameters based on the measurement of the bridgeÕs response to ambient vibrations. The bridge is subjected to widespread damaging phenomena, mainly concentrated on the external longitudinal beams. The SHM system is composed by six uniaxial accelerometers and 16 linear displacement transducers and its acquired data are constantly related to the environmental parameters (temperature and relative humidity).
