The footbridge dynamic analysis under the action of human walking involves many variables that
influence the structure. With this in mind, this article analyzes the dynamic responses of composite material
footbridge with different spans submitted to the action of human walking in order to measure the increase of
damping ratio on footbridge caused by the human-structure interaction. Two models used to represent the action
of human walking: the moving biodynamic model (MBM) and the moving force model (MFM). Analyzing the
difference between the results obtained from each of the models it is possible to find the increase of the damping
ratio of the structure in the presence of pedestrians.
