Performance Of Post-Tensioned Curved-Strand Connections In Transverse Joints Of Precast Bridge Decks, Zane B. Wells

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In order to minimize traffic delays on the nation’s bridges, precast concrete bridge decks have been utilized to quickly and efficiently construct bridges. These precast concrete decks are cast off site and transported to the bridge after they have cured. The decks are then placed onto the bridge and grouted into place. These precast panels have an inherent weakness in that the joints between adjacent panels tend to leak. In order to mitigate leaking of the joints, two adjacent panels are typically post-tensioned together. A variation on the standard post-tensioning in use by some DOT’s was designed and investigated in …
