Experiments are detailed and results are given of stresses and deflections under prestress, wheel loading, and H sub 20 S sub 16 T sub 16 for an elastic single-cell simply supported box girder model of realistic section shape. The model was tested under three different conditons of internal diaphragms. Theoretical anlayses from six different analytic methods (three-dimensional finite- element, folded-plate, finite-strip, 2-dimensional finite element plus grid, beam-on-elastic foundation analogy, and equivalent grillage methods of analysis) were assessed on the basis of their ability to predict experimental behavior. A three-dimensional finite-element method gave best results. Conclusions based on the theoretical results and on the experimental results are presented and compared.
