ADVANCED MONITORING SYSTEMS FOR LONG-SPAN BRIDGES: FE MODELING

In the United States, over 45% of the 575,000 highway bridges are now suspected of being either functionally obsolete or structurally deficient. Repair or replacement of these bridges will cost billions of U.S. dollars. Similar phenomena are occurring in other regions of the world. The serviceability of these bridges, and thus the highways, will affect the area's economic future, productivity, and ultimately the people's quality of life. Early detection of any material and structural damage will guarantee tremendous savings in repair cost and avoid unnecessary closing to traffic. A monitoring system is not only used to detect bridge damage but more importantly to determine when a critical state of the structure has been reached. In recent years, various monitoring and diagnostic hardware have been developed. In this paper, the finite element (FE) modeling technique of the long span bridge for the health diagnosis of the structural system is discussed. The FE model was verified using experimental data.
