Prefabricated bridge components are in increasing demand for accelerated bridge construction. Precasting eliminates the need for forming, casting, and curing concrete in work zones and makes bridge construction safer while improving quality and durability. Precast bridges consisting of pretensioned girders, posttensioned spliced girders, trapezoidal open box girders, and other types of superstructure members are often used for accelerated bridge construction; however, bridge engineers are concerned with the durability and performance of bridges made of precast members in areas of high or moderate seismicity. The applicability of the AASHTO load and resistance factor design specifications to precast prefabricated bridges in areas of high or moderate seismicity was examined. The different seismic design methodologies were reviewed and guidance in their application to precast bridges is provided. The Washington State Department of Transportation design criteria and recent research and bridge projects using the accelerated bridge construction technique in Washington State are reviewed.
