Abstract:

Maria Q. Feng

Elaborate infrastructure systems lie at the heart of the U.S economy and are an essential part of the lives of all of us.   The vast majority of these systems are over 40 years old.   Many are approaching one hundred.  They are not only deteriorating from age, but are also increasingly vulnerable to natural or man-made threats.  In the context of ongoing budgetary conflict and crises, a new paradigm is required to meet the challenges of intelligent infrastructure maintenance.

This talk explores the emerging applications of sensor-based technology to monitor such systems.   By monitoring structural integrity and providing objective, quantitative data, sensor technology has the potential to identify and prioritize those systems most in need of repair.  Limited resources can then be most effectively directed.   The major challenges that limit wider use of structural health monitoring will be discussed, along with recent efforts to address these challenges by developing innovative sensors meeting unique demands and advanced tools for reliable structural health diagnosis.
