What is Dynamic Analysis of Morava Footbridge about?

Dynamic analysis was performed on the Morava footbridge to evaluate vibrations from pedestrian loading. Eigenvalue analysis found the first vertical natural frequency was below 5 Hz, requiring further evaluation. Loads from walking pedestrians were modeled as harmonic forces between 1-3 Hz vertically and 0.5-1.5 Hz horizontally based on Eurocodes. Time history analysis was used to evaluate vibrations from a crowded scenario, modeled as periodic loads over 20 increments of the loading period.
