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 of the Clifton Suspension Bridge, UK
Proceedings of the Institution of Civil Engineers - Bridge Engineering, 2008Detailed vibration measurements were taken on the Clifton Suspension Bridge in Bristol, England to define its basic dynamic characteristics in normal conditions and then to assess its dynamic response to crowd loading; 27 vibration modes were identified with natural frequencies below 3 Hz.

Lateral Pedestrian-Induced Vibrations of Footbridges: Characteristics of Walking Forces
Journal of Bridge Engineering, 2014The forces a walker exerts to an oscillating floor differ significantly from those exerted to a fixed floor. This is because of a natural and unconscious gait modification, deriving from the necessity of minimizing energy consumption while maintaining balance. Among other factors, these forces depend on the frequency and amplitude of oscillation of the

Stability analysis of pedestrian-induced large lateral vibration on a footbridge
Structure and Infrastructure Engineering, 2020Stability analysis for pedestrian-induced vibration on footbridges is a complicated and multidisciplinary problem, which includes a series of complex mechanics, such as pedestrian–bridge interactio...

Prediction and Control of Pedestrian-Induced Vibration in Footbridges
Journal of the Structural Division, 1982Footbridges vibrate because the forces imparted by the user are applied with the frequency of the pace and movement, however small, is therefore a forced vibration. In instances where the pace coincides with a structure resonant frequency dynamic movement can be quite large and the user may be disturbed or even alarmed.

A Theory Treatment of Pedestrian-Induced Lateral Vibration of Structure
Journal of Dynamic Systems, Measurement, and Control, 2017The lateral excessive sway motion caused by pedestrian traffic has attracted great public attention in the past decades years. However, the theories about exploring the effect of pedestrian on the lateral dynamic properties of structure are scarce. The new contribution of this paper is that a new pedestrian-structure system is proposed for exploring ...

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 ...

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.

This paper is based on field measurements that were undertaken in a facility housing ultra-low level vibration sensitive equipment. The aim of these tests was to better understand the vibration transmission from an overhead pedestrian footbridge to a pile supported experimental floor and the supported vibration sensitive equipment.
