How Does A Tilt Bridge Work?

As the arch tilts lower, the pathway rises, each counterbalancing the other so that a minimum of energy is needed. The resultant appearance in motion leads to it sometimes being called the “eyelid bridge”, since its shape is akin to the blinking of an eye if seen from along the river.

How did they stop the Millennium Bridge from wobbling?

They concluded that making the bridge stiffer, to move its resonant frequency out of the excitation range, was not feasible as it would greatly change its appearance. Instead, the resonance was controlled by retrofitting 37 viscous fluid dampers to dissipate energy.

Does the Millennium Bridge still wobble?

Engineers fixed the Millennium Bridge’s swaying issues by retrofitting the structure with 37 energy dissipating dampers to control the horizontal movement, and another 52 inertial dampers to control the vertical movement.
