CEE Seminar: Instrumentation Design for Bridge Structural Health Monitoring
San Ramon, CA
Abstract: There are more than 600,000 bridges in the U.S., and more than 15 percent are considered structurally obsolete or deficient. The majority of bridges are only inspected annually. Adoption of modern structural health monitoring (SHM) has been very slow. From newspaper articles it seems such SHM systems could cost upwards of $200,000. In this seminar, the speakers will share their experience developing real-time, continuous SHM for bridges. In addition, key engineering issues and decisions will be discussed. The lecture will present and contrast approaches based on micro-electro-mechanical systems (MEMS) and fiberoptic sensors.
