- Synchronisation of pedestrians to lateral structural motion has been widely considered the driving mechanism of excessive lateral vibrations, e.g. those of the London Millennium Footbridge. Tests were conducted on a custom-build state-of-the-art experimental setup incorporating laterally-oscillating instrumented treadmill, virtual reality and automatic speed control. Synchronisation was rebutted as the mechanism leading to structural instability, but a new “phase-pulling” mechanism was discovered. This work led to the award of £3.25M EPSRC grant EP/P020690/1 – the biggest ever investment by the UKRI (then RCUK) in research on vibration serviceability.
