Abstract
In bridges built with T-shaped concrete beams, longitudinal joints are used to connect each T-beam to the beams next to it. These joints often experience strength and durability issues that require frequent maintenance and repair. Newer, technologically advanced materials show promise at not only improving the performance of these joints but also increasing the service life of the entire bridge. Researchers developed and tested a short-span bridge design that incorporates two such materials: ultra-high-performance concrete (UHPC) and reinforcing bars made of corrosion-resistant, high-strength steel.
