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 the additional insight that the results provide on the complex vehicle-bridge interaction problem. The results are presented using three 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 effect occurs in the vicinity of the mid-span section and can be of significantly higher magnitude when compared to the maximum at mid-span.||Funding Details:||European Commission - Seventh Framework Programme (FP7)||Type of material:||Conference Publication||Publisher:||European Association for Structural Dynamics||Start page:||1169||End page:||1174||Keywords:||Vehicle-Bridge Interaction; VBI; DAF; Dynamics; Bridge; Truck||Other versions:||http://paginas.fe.up.pt/~eurodyn2014/||Language:||en||Status of Item:||Peer reviewed||Is part of:||A Cunha, E.
