Galena Creek Bridge Health Monitoring Instrumentation (NDOT 743-18-803)
Near the end of construction of the Galena Creek Bridge, Nevada DOT and the University of Nevada, Reno, collaborated to install instrumentation to provide dynamic monitoring of the main arch, which spans 689 feet over Galena Creek. The instrumentation was intended to be a permanent structural health monitoring (SHM) system, but after initial testing and monitoring, the system was not maintained. Though the system has continued collecting data, it must be replaced for renewed monitoring efforts. The Research Team has identified a unique approach for the Galena Creek Bridge SHM system. A proven SHM system for buildings will be adapted for this bridge application. Similar hardware components to those used by the U.S. Geological Survey (USGS), including a recorded, a Linux-based computer system, and accelerometers, have proven to be accurate and reliable, and will be used on this project. Methodology will include Literature Review, Identification of parameters of interest and notification strategies, developing an instrumentation plan and deployment strategy, producing benchtop testing at University of Nevada, Las Vegas (UNLV), field deployment, and finally field calibration. After final field calibration and long-term field testing, the final report and implementation plan will be produced. The research proposes to implement a SHM system over the Galena Creek Bridge for continuous monitoring. Structural response will be measured for various loading conditions, and notifications will alert appropriate authorities after an extreme event, allowing immediate emergency response, as needed and as appropriate.
