SHM of Highway Bridges

Bridge Condition Monitoring and Assessment using Sensors in Low-Power RF Networks
Primary research effort is on the development and deployment of dense low-cost sensors interfaced with low-power RF communcations networking (wireless sensor networks) to obtain real-time vibration, strain, and temperature measurements from in-service highway bridges. From these case studies, condition assessment methodologies, in the form of structural identification, damage diagnostics routines, and experimental load ratings, are applied to derive information of value to bridge inspection and maintenance engineers.
