NU girders are prestressed concrete girders that can be either pretensioned or post-tensioned developed by the Nebraska Department of Roads in the early 1990s. NU girders are characterized by their wide bottom flange, which enhances the compressive strength in negative moment regions for continuous span designs, and to allow placement of a large number of strands in the bottom flange for simple span designs. This is particularly helpful when high strength concrete is used.
NU Girders are available in a range of sizes with an upper flange width of 49.5” (126 cm), lower flange width of 42” (102 cm), and depths between 47.25”-110.25” (120-280 cm). NU Girders are available in typical lengths between 65’-210’ (20-64 m).
