Feasibility of Vibration-Based Long-Term Bridge Monitoring Using I-35W St. Anthony Falls Bridge

Status:  Complete
Report Date:  02/06/2017

Summary:

Researchers developed a method of analyzing accelerometer data from the I-35W St. Anthony Falls Bridge to establish how the bridge naturally vibrates in response to traffic, wind and other environmental conditions. With this fingerprint of the bridge's vibration, engineers have a baseline against which to measure anomalies in bridge monitoring data that might indicate structural damage.
