​The Dublin Spire was commissioned in July 2003. The 120-meter-high spire is only 3 meters wide at its base, making it the world’s tallest sculpture. This extremely slender design meant that stability during certain wind events could be a concern. A multi-modal approach to damping was required.
Motioneering was retained to design, fabricate, and install two tuned mass dampers of 1250 kg and 800 kg, which increased the damping to ensure the aerodynamic stability of the Spire is maintained.
