PREDICTION OF BRIDGE GIRDER STRESS HISTOGRAMS FROM TRUCK TYPE DISTRIBUTION

Stress history studies are conducted so that bridge girder stresses due to various types of truck loadings can be predicted. Being able to predict these stresses obviates having to measure them for every bridge. This paper presents a seven-step procedure for using stress history data to predict stress in bridge girders. Stress data for 3,120 trucks identified by type and lane location and weight data from 3,865 trucks identified by type were obtained. A comparison between the stresses and weights showed that there were notable similarities in the shapes of the two distributions. The ability to simulate or predict stresses based on truck type, lane location, and weight distribution will eliminate the need for complicated and costly field measurement of stresses.
