Overview of 40 Bridge Structural Health Monitoring Projects

摘要

In the last 15 years, fiber optic sensing has become a useful and increasingly widely used tool for structural health monitoring of bridges and other civil structures. We have been fortunate to participate to their development and introduction to real field applications. This paper is an overview of 40 bridge monitoring projects carried out over the last 15 years in 13 different countries. 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. Finally, as an example of a Structural Health Monitoring project, we will briefly present the Monitoring system of the new I35W St. Anthony Falls Bridge in Minneapolis.
