Influence Of Shear Key Performance On The Fatigue Life Of Adjacent Beam Bridges, Sara Roberts

All Theses

Adjacent beam bridges, such as box beams and hollow core bridges have been one of the most popular forms of precast prestressed bridges in the past. Recently, an awareness of major durability problems has led owners to make improvements to the old standards or move away from the system completely. These issues usually stem from the breakdown of the shear key which provides continuity between adjacent members. This research focuses on determining the best improvements that will reduce durability issues and increase the bridge's service life.
A review of previous research performed on adjacent beam bridges is performed, focusing on …
