- A novel experimental setup was developed to investigate the wobbly behaviour of London Millennium Footbridge under crowd loading. The novelty relies on the incorporation of automatic treadmill-speed control mechanism and immersive and interactive virtual-reality environment into a laterally-driven custom-built instrumented treadmill. This ensured adaptive pedestrian gait and visual conditions representative of real-world experience. The setup enabled asymmetric pedestrian stepping behaviour and, for the first time, all self-excited force components to be identified, responsible for bridge instability. The setup was showcased in a news piece “Bridge Collapse” published by The Verge Science, attracting over 450k views in the first 5 days.
