“… six pedestrian bridges on metal beams, composite steel-concrete beams, composite beams with holes in the steel webs, beams with corrugated webs and truss footbridge, all of these having the span of 24.00 m and the width between parapets of approximately 3.00 m. The structures listed above are presented detailed from the point of view of the dynamic behaviour in the papers [3], [5], [6], [7] and in the handbook [1];…”

In this paper several aspects regarding the dynamic behaviour of the steel footbridge structures under the action of the loads generated by the pedestrians’ displacement, correlated with the traffic comfort of the pedestrians crossing the structure are presented. The crossing pedestrians’ comfort criterion requires the values of vibration frequencies and accelerations of the structures in certain limits so that the vibration amplification or resonance is avoided. The paper takes under investigation eight footbridges on steel, composite steel-concrete girders and a cable stayed structure from the viewpoint of frequencies in vibration Mode 1 in a vertical plane, generated by their own weight - natural frequency, or from a partial pedestrian loading, as well as the resulting resonance risk and the traffic comfort.

Pedestrian bridges are constructions that are part of the category Bridges, having the particularity that due to much lower loading as compared to that of road or railway bridges, their decks are much slenderer, and can be included in the category of light structures. In this paper several aspects regarding the dynamic behavior of the footbridge structures under the traffic actions correlated with the pedestrians’ comfort are presented. The comfort criteria depend of the frequencies and accelerations of the structure and have to be situated between certain limits. If the frequencies and accelerations of the structure are in the critical domains, measures to modify them have to be taken, some of them being presented in this paper as they are the most usually used.
