Structural Monitoring of Steel-Member Bridges with Fatigue Life Prognosis due to Dynamic Vehicular Loads

This project will develop an integrated hardware and analytical framework that enables real-time bridge structural monitoring and remaining fatigue life estimation. PI Wang has over 20 years of experience in structural dynamics and wireless structural monitoring. His research group has co developed a modular wireless sensing device that can perform high-rate data acquisition. The Martlet smart wireless sensing system is particularly designed for civil structural applications. Building blocks of this system are individual wireless sensing units. With solar power, each wireless unit can collect data from various analog sensors, such as strain gages, string potentiometers, accelerometers, etc. Cost of the wireless system is only a fraction of conventional cabled sensing systems. The system is also capable of routing data through cellular network. This project will develop an integrated hardware and analytical framework that enables real time bridge structural monitoring and fatigue life prognosis.
