Vibration serviceability of footbridges under human induced dynamic loading attracted a lot of attention of the research community in the last several years. Most often, crowd loading scenario and human‐human and human‐structure interaction are analysed. However, between the crowd loading scenario and the single pedestrian that most often features in the current design guidelines, there are at least two other loading scenarios that could be relevant for footbridge design: groups of people walking together and the normal pedestrian traffic, which is usually related to the situation where the people’s movement is not spatially restricted. On top of this the vandal loading should be considered as well. This paper presents a combined numerical and experimental study of a box girder footbridge that is lively in the vertical direction. An attempt is made to analyse most relevant loading scenarios for this bridge residing in the city centre of the capital of Montenegro. The loading scenarios are presented in form of a risk matrix. Experimental data for some loading scenarios are collected and compared with numerical simulations (based either on the current guidelines or on some uncodified procedures). It could be concluded that the existing design guidelines should be used with caution, and that the alternative methods of vibration serviceability evaluation might often be preferable.
