Comparisons between induced girder stresses and corresponding vehicle weights. Paper presented at the 51st Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1972.

The partical results of 4 loading history field tests on 4 simple-span, cover-plated bridges in Maryland are reported. The resulting stress-range data are compared to the stiffness of a typical girder and the corresponding vehicle gross weights.
