摘要：	The goal of this research is to implement the continuity detail, which has been developed in bridges in Nebraska. Based on internal meetings of the Nebraska Department of Roads (NDOR) bridge engineers and University of Nebraska Lincoln (UNL) researchers NDOR agreed to implement the new detail for making the girders continuous for a bridge deck weight. This detail is expected to increase the span-to-depth ratio of the NU-Girders and it will be workable regardless the type of diaphragm used over pier locations (a continuous concrete diaphragm or steel diaphragm). This project is also intended to present the investigation of the implementation bridges. The ultimate goal is that the system totally replaces the current inferior system of continuity in the deck for superimposed loads only. It is expected to be the standard system for precast concrete girder construction for Nebraska and the nation as well.
