Arrow Fully Precast Bridge Bents for Use in Seismic Regions

Fully Precast Bridge Bents for Use in Seismic Regions. (Berger/Abam Engineers) Prefabricated bridges bents, also known as piers, have not been used in seismic regions because accepted methods of making connections that are both structurally robust and quick to assemble were not known and were not addressed in design specifications. This project will demonstrate a totally precast concrete bridge bent system that can be used in seismic regions. This new technology, to be used on a bridge in Washington State, allows the main elements of bridge bents to be prefabricated off site. Then the segments are moved into place and assembled to form the bents, greatly reducing construction time and traffic delays. Award amount of $400,397.
