Abstract

The Colle Isarco Viaduct is one of the most important structures on the Italian Brenner motorway. It was designed and built between 1968 and 1971. The bridge has been subject to maintenance work on several occasions in view of increasing traffic loads, and is now being strengthened with the addition of an external post-tensioning system. The effectiveness of this work is to be measured by a system that: (1) observes bridge deflection at two topographic stations; (2) monitors strain and temperature with fiber optic sensors and thermocouples; (3) records the tension in the new post-tensioning cables. In this paper, we illustrate the work in progress and discuss the criteria used to design the monitoring system. We also describe in details how bridge behavior is interpreted using a finite element model and how the bridge state is expected to be identified based on monitoring observations.
