Project Description

Design of a new pedestrian bridge across the Yarra River adjacent to the Melbourne Convention Centre gave rise to concerns that footfall disturbance at or close to the natural frequency of the structure could result in high amplitude oscillation on the bridge.

To mitigate against this possibility, the designers commissioned Embelton to design and manufacture a tuned mass damper capable of countering this oscillation.

Embelton designed, manufactured and delivered onsite the tuned mass damper configured to offset a theoretically calculated natural frequency of 7hertz. After the bridge’s opening, it was found the actual natural frequency was different to the calculated frequency, requiring Embelton to re-tune the damper to meet the actual oscillating frequency of the bridge.
