Structural Health Monitoring (SHM) is emerging as an important element for sustainable management of public works infrastructure systems such as bridges, tunnels, buildings, and dams. Our research focuses on bridge structural health monitoring, in particular the implementation of bridge condition assessment using static and dynamic non-destructive tests. Finite element models are calibrated with measured data for load rating and SHM. Currently we are performing SHM on the Powder Mill Bridge (Vernon Avenue Bridge), Tobin Memorial Bridge (Charlestown, MA), and the Dowling Hall Footbridge (Medford, MA).
