This is a sequel to my piece no longer wobbly about the Millennium Bridge in London. The design engineers have produced this website to explain their diagnosis of the problem—synchronous lateral excitation, a sideways sway caused by walkers’ footfalls. Dampers to stop the bridge getting excited were the solution.
The website is neatly written, with excellent pictures and video footage. I’d be game to walk across the bridge.
