WebFeb 18, 2024 · Excessive lateral vibrations of footbridges induced by pedestrians have been investigated from many perspectives. Nakamura’s model is a famous model … WebIn specifying the magnitude of the dynamic load to be used in design rules it was decided that the more sensitive existing footbridges should be considered just acceptable. This led to a dynamic load equivalent to one pedestrian. Abnormal loading by a group of vandals deliberately exciting a footbridge at its natural frequency was considered.
WebMay 22, 2024 · Footbridge Vibration Design presents new approaches, numerical tools and experimental tools for assessing and controlling pedestrian effects. Moreover, it includes a number of reference cases dealing with design and control. Focussed on the translation of these findings into practical recommendations, guidelines, codes and design tools for … WebSome recently constructed footbridges have been criticised by the public for their susceptibility to vibration. A limit to the allowable acceleration of a footbridge deck, vibrating under pedestrian loading, is proposed, based on experimental studies of human tolerance. A formula is derived for calculating the maximum vertical acceleration of a footbridge due …
