DISTRIBUTION OF WHEEL LOADS ON HIGHWAY BRIDGES

STUDY WAS CONDUCTED ON SHORT-AND MEDIUM-SPAN BRIDGES OF THE BEAM-AND-SLAB, MULTI-BEAM, AND BOX GIRDER TYPES TO DEVELOP CRITERIA FOR DISTRIBUTION OF WHEEL LOADS ON HIGHWAY BRIDGES. THE ORTHOTROPIC PLATE THEORY WAS JUDGED TO BE MOST ACCURATE FOR BEAM-AND-SLAB BRIDGES. FOR MULTI-BEAM BRIDGES THE ARTICULATED PLATE THEORY GAVE THE MOST ACCURATE RESULTS. FOR CONCRETE BOX GIRDER BRIDGES, THE FOLDED PLATE THEORY APPEARS TO BE MOST APPLICABLE. A REPLACEMENT IS RECOMMENDED FOR ARTICLE 1.3.1(B) OF AASHO SPECIFICATIONS FOR HIGHWAY BRIDGES.
