Abstract
Colle Isarco Viaduct is one of the most important infrastructures on the Italian Brenner freeway. It was designed and built between 1968 and 1971. The bridge was subject to maintenance work on several occasions to improve the performance against increasing traffic loads, and is now being strengthened with the construction of an external post-tensioning system. The effectiveness of this work is to be measured by a system observing the deck deflections from two topographic total stations, monitoring strain and temperature with fiber optic sensors and thermocouples, and recording the tension in the new post-tensioning cables. In this paper, we illustrate the ongoing work, describe in detail how the bridge behavior is interpreted using a finite element model and how the bridge condition is expected to be determined based on monitoring observations. Finally, we also discuss the criteria applied to design the monitoring system itself.
