Civil engineers for being sometimes aware of the problems caused by excessive vibration caused by the resonance phenomenon on the footbridges. The sources that cause this phenomenon are several and have different origins, for example, pedestrians practicing some ways of walking, exceptional agglomerations of pedestrians, strong winds, rain, etc. The objective of this paper is to present a literature review that allows understanding of the types of dynamic loads that are introduced in the structures due to pedestrian movements. The study was developed from the theoretical analysis of several authors about the movement of pedestrians in structures. The various modeling proposals allow the use of up to five pedestrian action harmonics or only those that consider the greatest resonance effect. It was verified that the proposed models are differentiated, mainly, by the number of harmonics considered during the action of pedestrians.
