Sažetak
The problem of vibrations on pedestrian bridges is a topic that has been intensively explored over the past 20 years. Although an incredibly large amount of research has emerged on the topic [1], the problem of vibrations is very poorly represented in European standards. Annex B to Eurocode EN 1995-2:2013: Design of timber structures [2] gives expressions to determine the vertical acceleration of the timber bridges with simply supported beams or truss systems, depending on the natural frequency of the bridge, the number of pedestrians crossing the bridge and the way they move across the bridge (walking or running). UK National Annex to Eurocode EN 1991-2:2003: Actions on structures [3] gives models of pedestrian loads, using which is possible to calculate the vertical acceleration of the bridge, also depending on its natural frequency, the number of pedestrians and the way they move across the bridge. In this paper, the calculations of maximum vertical acceleration on two fictional pedestrian bridges will be made according to these two different European standards. The results of the calculations will be presented and compared.
