Disaster Strikes on the Wobbly Bridge | The London Millennium Bridge #22

Hard Tech Podcast · 1 Sept 2024 · 8m

What this episode covers

The host discusses the London Millennium Bridge, designed by Norman Foster and Arup, which suffered from synchronous lateral excitation on its opening day in 2000 due to pedestrian footfall matching the bridge's natural frequency. The incident was resolved by installing 91 dampers, including 52 tuned mass dampers and 37 viscous dampers, to absorb kinetic energy and stabilize the structure. The episode highlights the engineering lesson regarding the interaction between human behavior and flexible structural design.
