Prestress Losses and Development of Short-term Data Acquisition System for Bridge Monitoring (Jun 2019, MPC-19-387)
Justin Pace, Paul Barr, and Phillip Powelson

When a vehicle drives over a bridge, each bridge girder carries a portion of the vehicle's weight. This load causes strain in the bottom of the bridge girders. However, depending on where the vehicle is located on the bridge, some bridge girders carry a higher percentage of the vehicle's load. This study...

 
Long-Term Behavior of Precast Concrete Bridges (Jul 2018, MPC-18-352)
Phillip Powelson, Paul J. Barr, and Marv W. Halling

For this research, sensors were used to investigate the differences in prestress losses and temperature gradients in a concrete deck bulb tee girder bridge. The Millville Bridge was built as an access point to the Ridgeline High School in Millville, Utah. The bridge was built in 2016 and presently supports...

 
Behavior and Analysis of an Integral Abutment Bridge (Sep 2013, MPC-13-256)
Paul J. Barr, Marv W. Halling, Conner Huffaker, and Hugh Boyle

As part of a study to develop design guidelines for integral abutment bridges, a study was undertaken in which the bridge movement of the 400 South Street Bridge was surveyed for one year to quantify changes in bridge movement due to temperature variations. These quantitative bridge movements were compared...
