Long-Term Static Structural Health Monitoring
In the last 15 years, Structural Health Monitoring has become a useful and increasingly widely used tool for the construction, management and lifetime extension of bridges and other civil structures. A lot of attention has been devoted to dynamic monitoring of structures in the aim of performing system identification and damage detections. The monitoring of static parameters such as strains, deformations, tilts and displacements is another useful and complementary tool to asses the long term performance and to identify changes in behavior that are often difficult to spot with dynamic monitoring. This paper is based on the experience gathered in monitoring more than 40 bridge monitoring projects carried out over the last 15 years using advanced sensing systems including fiber optics, GPS and corrosion sensing. In particular we concentrate on the analysis of the different types of bridges that were monitored, their situation (new construction, existing structure, refurbishment...) and the main purpose of the installed monitoring system. Two main categories emerge form this analysis: new bridges with innovative aspects or particular relevance and existing bridges with known deficiencies. A methodology to design an integrated monitoring system capable of monitoring the whole structure with a limited number of sensors, of the right type and placed at the right locations will be introduced. Finally, an application example of Structural Health Monitoring system design and implementations for the I35W will be briefly presented.
