摘要：	The report presents finite element models for a two-span jointless HPC bridge built in Dickson County, TN. The model accounts for prestress in the girders, reinforcing bars in girders, deck slab, and substructure. It also allows for material nonlinearities in concrete, abutment backfill materials, and the supporting piles. The results of a series of simulation are presented accounting for truck loading, as well as temperature, creep and shrinkage effects. A series of parametric studies are also undertaken to determine the effects of angle of skew on distribution factors. All computer simulation results are compared with actual test data accumulated over a period of four years from live load tests as well as continuous monitoring temperature, deflection, and strain variations resulting from environmental actions. Important conclusions are drawn at the end.
