FINITE-ELEMENT LOAD DISTRIBUTION FACTORS FOR MULTI-T-BEAM BRIDGES

In this paper the determination of the lateral distribution of wheel loads on multi-T-beam bridges using the finite-element method is presented. The results are compared with existing applicable AASHTO specifications and other methods found in the literature. The evaluation of lateral wheel load distribution is of importance because of the significance of the localized effects of wheel loads on stresses and deflections of individual T-beams and must be determined with sufficient accuracy. It is found that significant differences exist in wheel load distributions determined using applicable specifications and other methods compared with distributions determined using the finite-element method of structural analysis.
