Abstract: The objective of this research is to monitor the real-time structural health of an urban bridge 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 assess 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, 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.
