Design of Footbridges against Pedestrian-Induced Vibrations

Journal of Bridge Engineering, 2016
AbstractIn 1999 and 2000, the two vibration incidents at the Paris Passerelle Solferino Bridge and the London Millennium Bridge triggered a major revision of existing knowledge concerning footbridge response to pedestrian-induced actions. In the last 15 years, an incredibly large amount of research has emerged on the topic.

Pedestrian-induced torsional vibrations of suspended footbridges: Proposal and evaluation of vibration countermeasures

Engineering Structures, 2012
Abstract The aim of the paper is to propose and evaluate different design arrangements addressed to mitigate the in-service pedestrian-induced torsional vibrations of lightweight suspended footbridges. All the proposed structural countermeasures are characterised by the addition of few elements to the original structure, i.e.

Pedestrian-induced lateral vibrations of footbridges: A literature review

Engineering Structures, 2012
Abstract The earliest scientific descriptions of excessive pedestrian-induced lateral vibrations are dated back to the 1970s, but it was not until the beginning of the new millennium that bridge engineers fully comprehended the potential negative effect of pedestrian crowds on long-span footbridges. Following the unexpected serviceability failures of

Mitigation of Pedestrian-induced Vibrations in Suspension Footbridges via Multiple Tuned Mass Dampers

Journal of Vibration and Control, 2010
The dynamic response of suspension footbridges to pedestrian-induced excitations and its passive mitigation, via multiple tuned mass dampers (TMDs), are investigated. First, the nonlinear equations of motion are obtained assuming finite planar motions of the suspension bridge. A suitable approximate version of the equations of motion is shown to be in

London Millennium Bridge: Pedestrian-Induced Lateral Vibration

Journal of Bridge Engineering, 2001
The London Millennium Footbridge is located across the Thames River in Central London. At its opening on June 10, 2000, the bridge experienced pedestrian-induced lateral vibration. Observations on the day of opening and studies of video footage revealed up to 50 mm of lateral movement of the south span and 70 mm of the center span.

Pedestrian-induced vibrations on footbridges: advanced response analysis

Bridge Structures, 2007
Pedestrian-induced vibrations (PIV) on footbridges, overpasses, and floors are attracting more attention by designers and are becoming as important to dynamic excitation to consider as wind and earthquakes. A key reason for this trend is the public awareness and higher performance standards set on new projects where better comfort is sought and lively ...
