WebJan 19, 2024 · The stability is also related to dynamic response and vibration. It is not the main issue for a majority of short and medium-span road bridges, but it is an important factor in the design of footbridges. If the structure has a low natural frequency, it might lead to unstable lateral response and loss of stability. 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 …
