A model of pedestrian-induced bridge vibration based on full-scale measurement

Engineering Structures, 2012
Abstract 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 ...

Factors that influence pedestrian‐induced vibration: A sensitivity analysis of GSA’s footfall package [PDF]

IntroductionAs we become more able to provide stronger structures with less material, a reduction in thickness to seemingly create a more optimal design for the strength limit state can lead to problems in other areas; namely the serviceability limit state for vibration. Structural vibration as a phenomenon has been studied for decades.

Generalized Inverted Pendulum Model for Pedestrian-Induced Lateral Vibration of Footbridge

International Journal of Structural Stability and Dynamics
Since the occurrence of pedestrian-induced large lateral vibration of the London Millennium Bridge in 2000, scholars have realized the complexity of pedestrian-induced lateral vibrations. Despite extensive research spanning over two decades, the underlying mechanisms between pedestrians and footbridges remain incompletely understood.

Pedestrian Induced Lateral Vibrations with Emphasis on Modal Energy Transfer

Already on the opening day of the Lardal Bridge in 2001 were large lateral vibrations observed. These excessive vibrations were seen as relatively dense and continuous flow of people was crossing the bridge. This type of observation has later been made for several other bridges, old as well as new.
