Laboratory Testing Of Precast Bridge Deck Panel Transverse Connections For Use In Accelerated Bridge Construction, Scott D. Porter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Precast concrete bridge deck panels have been used for decades to accelerate bridge construction. Cracking of the transverse connection between panels is a common problem that can damage deck overlays and cause connection leaking leading to corrosion of lower bridge elements.

To better understand the behavior of bridge deck transverse female-to-female connections, shear and moment lab testing were performed at Utah State University for the Utah Department of Transportation. Two existing UDOT connections were tested, a welded stud connection and a post tensioned connection. A variation of the welded connection using rebar was also tested. In addition, two new curved …
