This 101-story skyscraper was the tallest building in the world for six years. Motioneering designed the 660-tonne tuned mass damper that is the tower’s main supplementary damping system. In addition to supporting the building’s performance and the comfort of its occupants, the damper’s elegant single pendulum has become a noted tourist attraction.
 

This cantilever bridge features a 6cm thick glass walkway and extends 721m over the Grand Canyon. Our team created three tuned mass dampers to mitigate the potential for uncomfortable motion on this unique structure, which is sensitive to both wind and pedestrian movement. The system is fitted inside the structure’s support beams and designed to avoid obstructing visitors’ views to the canyon below.

Soaring 426m above Manhattan, this tall, slender tower became an instant icon. Due to its 15:1 height-to-width ratio the tower is susceptible to oscillating movements as well as swaying. The Motioneering team designed the two 660-tonne tuned mass dampers that mitigate the building’s wind-induced motion.
