• Abstract:
  The high-performance concrete (HPC) 120th Street and Giles Road bridge in Sarpy County, Nebraska consists of three equal 22.9-m (75-ft) spans and is 25.8 m (84.7 ft) wide. The HPC bridge used seven NU1100 (1100-mm-high) simple-span girders made continuous for live load using negative-moment reinforcement in the deck. The NU girder series is metric. These Bulb-Tee girders were developed in a girder optimization program conducted by the University of Nebraska at Omaha. Girder spacing is 3.8 m (12.4 ft) on center and the deck thickness is 191 mm (7.5 in.). The benefits are apparent as fewer girders were required in the HPC superstructure. A nearby bridge constructed without HPC provides a direct comparison of the durability aspects of HPC.
