Structural Health Monitoring of Bridges Using Wireless Sensor Network

Abstract:

The objective of this research is to monitor the structural health of an urban bridge real-time in the City of Youngstown, OH, by applying new technologies involving acceleration sensors, wireless networks, internet web services, Java SunSPOTs and embedded systems. The research was aimed to assessing the current structural health and future performance of the bridge with any immediate repair or replacement needs. A total of 8 wireless accelerometer Java SunSPOT Sensors, developed by Sun Microsystems (now part of Oracle), were customized and deployed at structurally critical locations on the bridge. Acceleration data were collected via real-time wireless sensor network. Later the acceleration data were analyzed to assess the structural condition of the bridge.
