This paper quantifies the underestimation of bending moment that results from exclusively considering the midspansection of bridges when calculating vehicle-bridge dynamic interaction. A numerical model of a simply supported Euler-Bernoulli beam, traversed by a 1-DOF vehicle, is used to evaluate the differences. The simplicity of the model is justified by theadditional insight that the results provide on the complex vehicle-bridge interaction problem. The results are presented usingthree dimensionless parameters that uniquely define the solution, taking into account the coupled system (vehicle and beam)frequencies and masses as well as the velocity of the passing vehicle. The results show that the overall maximum load effectoccurs in the vicinity of the mid-span section and can be of significantly higher magnitude when compared to the maximum atmid-span.
