Checking the limit state of vibrations on two pedestrians’ bridges in Rijeka

Since large number of scientific papers have been written in the last twenty years on the topic of vibrations on pedestrian bridges, there have been certain changes in the way of checking the limit state of vibrations in European standards and design guides [1]. Since this issue is very common in everyday life when people crossing pedestrian bridges, there is a need for checking the limit state of vibrations on pedestrian bridges which were built before the adoption of applicable standards, and which are still in use today. In this paper, the calculations of limit state of vibrations will be made on two pedestrian bridges over the Rijeka bypass, which were built in the 1980s and have remained in operation to this day. The calculations will be made according to two valid European standards for checking the limit state of vibrations: Annex B to Eurocode EN 1995-2:2013: Design of timber structures [2] and UK National Annex to Eurocode EN 1991-2:2003: Actions on structures [3] using Lusas Bridge 18.0 software for calculation. The results will be explained, and the calculation will show whether these bridges meet the criteria by today’s European standards.
