The dynamic analysis of a fifty-meter-long arch footbridge built in Poland is presented in the paper. The investigation focused on the comparison of dynamic responses to different types of dynamic loading, specifically pedestrian movement, traffic loads, mining tremors and seismic shocks. The FE model was created in the ABAQUS software. It transpired that the vibration level exceeded the thresholds ‘slightly felt’ in case of both, pedestrian and traffic loadings. The results also suggest that the safety of the structure is not threatened by this level of mining and seismic vibrations.
