Abstract
The footbridge in Radom is a suspended bridge of an interesting architectural form. The structure was de-signed for 4 kN/m2 of crowd loading. Dynamic calculations were not included in the design. The structure’s acceptance tests took place on the 14th of October 2016. The behaviour of the footbridge in static testing met the expectations. Unfortunately, as a result of dynamic tests, dangerous behaviour of the footbridge was revealed. A rhythmic jump test induced deck vibrations with an acceleration of 4.51 m/s2. For this reason, a newly built object has not been approved for use and the structure requires installation of additional damping devices. The article presents analyses of the load test design stage, describing performed tests and their re-sults, showing the comparison of theoretical and measured parameters and further indicating the improper dynamic behaviour which prevented the structure usage until the repair.
