Title: Comparision of Loads Around the World for Design of Highway Bridges

Abstract:Design live loads for major bridges in eighteen countries are compared by studying their effects on simple spans of 30 to 140 ft. (9 to 42 meters nominal). A very wide diversity in the design load effects such as maximum bending moments and shear forces is noted--the heaviest effect being about two and one-half times that of the lightest. This wide diversity cannot be easilty justified by the normal volumes of traffic loads in these countries. It is hoped a more uniform design load, if specified, will result in economy in some countries and perhaps greater safety in others.
