Vibration Analysis and Human Comfort Evaluation of Steel-Concrete Composite Footbridges Based on the Modelling of the Pedestrian-Structure Dynamic Interaction Effect

摘要

This work aims the development of an analysis methodology to investigate the dynamic behaviour of steel-concrete composite footbridges. The composite footbridge dynamic response is analysed based on two different strategies. Firstly, the traditional simulation of human walking, without consideration of the pedestrian-footbridge dynamic interaction effect is considered. On the other hand, the effect of the dynamics of the pedestrians while crossing footbridges in crowd situations is analysed and the pedestrian-footbridge dynamic interaction, based on the use of biodynamic models is investigated using a second strategy.
