STUDY OF TRUCK WEIGHTS AND THE CORRESPONDING INDUCED BRIDGE GIRDER STRESSES

EXAMINATION OF THE FIELD DATA, INDUCED GIRDER STRAINS, AND CORRESPONDING VEHICLE TYPE AND GROSS WEIGHT FROM FIVE SIMPLY SUPPORTED GIRDER SLAB BRIDGES HAS YIELDED A SERIES OF EMPIRICAL EQUATIONS RELATING INDUCED STRESSES AND VEHICLE GROSS WEIGHTS. THESE EQUATIONS ARE USED IN CONJUNCTION WITH LINEAR DAMAGE THEORY AND ESTIMATED VEHICLE WEIGHT AND VOLUME DATA TO PREDICT THE FATIGUE LIFE OF THE FIVE SPANS TESTED. A WIDE VARIATION IN PROBABLE FATIGUE LIFE RESULTED FROM THIS ANALYSIS. /AUTHOR/
