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

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.

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.

A Model of Pedestrian-Induced Bridge Vibration Based on Full-Scale Measurement
Engineering Structures, 2012Abstract It is now well-known that, under pedestrian excitation, flexible footbridges can exhibit large-amplitude vibrations that impact their serviceability. In particular, some footbridges of suspended spans have exhibited significant lateral oscillation due to pedestrian–bridge interaction.

A spectral approach for the analysis of pedestrian-induced vibrations of footbridges
, 2009 Modern footbridges are very slender structures, often characterized by natural frequencies within the range of the dominant walking harmonics; thus, they can be very sensitive to walking-induced vibrations. In the present paper, real pedestrian traffic conditions are modeled probabilistically, considering several sources of randomness among which ...

Measurement and prediction of the pedestrian-induced vibrations of a footbridge
Noise Notes, 2009Vibration serviceability has become an important issue in the design of modern slender footbridges with large spans. This paper presents the measurements and the numerical predictions of the footfall-induced vibrations of a pedestrian bridge. A series of experiments were carried out with different-sized groups crossing the bridge, varying in number ...

Pedestrian-induced vibrations on footbridges: advanced response analysis
Bridge Structures, 2007Pedestrian-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 ...

On the Dynamics of Pedestrians-Induced Lateral Vibrations of Footbridges
2012This chapter is concerned with the problem of the large horizontal oscillations induced on slender footbridges by the motion of pedestrians, a phenomenon which involves the synchronization between the motion of walkers and that of the bridge deck. We initially review the extensive technical and scientific literature, and then we focus on two models to ...
