In this study, the live-load moment-distribution factors (LLMDFs) were evaluated for an adjacent precast prestressed concrete box beam bridge. The bridge used a new shear key configuration, which was grouted with ultrahigh performance concrete (UHPC) and contained noncontact lap-splice dowel bars.AASHTO LRFO provisions is given. A fully worked numerical design example is included to demonstrate the proposed design procedure. Precast, prestressed concrete box girders are widely used in short and medium span bridges in North America.
