Abstract:

A typical span of the Little River overflow bridge located in McCurtain County, Oklahoma, a shear-critical prestressed concrete bridge identified by the Oklahoma Department of Transportation (ODOT) Bridge Division, is studied using a multidisciplinary approach. Field measurements are collected in terms of accelerations. They are processed in both time-domain and frequency-domain analyses. The results are validated and interpreted using the principles in structural engineering to reveal the insights about the bridge span; new findings are discovered and reported to the ODOT Bridge Division. These findings and our developed systematic approach will be widely disseminated in the ASCE structural health monitoring community given the inherent challenge in processing and understanding dynamic measurements of real-world structures. These data processing and result analysis efforts are the focus of this report, while snapshots of our other work, including finite element modeling of the bridge span, nonlinear system identification and model updating, are provided.
