Resulting experimental data, from testing two bridge structures, is compared to results from finite difference plate theory. Two bridge structures tested are: (1) 200-ft span through truss; and (2) 80-ft span composite slab-steel girder bridge. Strain data were obtained during the truss bridge tests, and both strains and deflections were obtained during the steel girder bridge tests. Results from the comparison of experimental and analytical data give excellent agreement. The analytical technique is computer oriented, requiring minor calculations in order to obtain the resulting data.
