Abstract:

This abstract documents and presents a research study/implementation project of structural health monitoring (SHM) systems on the Galana Creek Bridge, supported by the Nevada Department of Transportation under Project Agreement No: P743-18-803. Full-scale SHM systems, in combination with smart monitoring software, were designed and implemented on the northbound structure of the bridge to monitor the response and behavior of the bridge to various loadings in real time. Two SHM systems, which are a primary seismic monitoring system and a secondary exploratory system, were installed to measure the structural response to seismic activity as well as to routine traffic, thermal expansion and contraction, and wind events. The seismic system consisted of 33 accelerometers and a triaxial seismograph, while the exploratory system included an array of temperature, wind, displacement, and tilt sensors. The software implemented generates a comprehensive report on each predefined triggered event and sends real-time notifications to proper authorities within NDOT on the condition of the bridge following the trigger event. Ultimately, this project serves as an SHM testbed for NDOT and contributes to the advancement of SHM as a bridge safety and management tool.
