Thirty-six (36) Tuned Mass Dampers (TMDs) were installed in the roof structure of a Dubai racecourse stadium for wind vibration control. The stadium has one of the longest cantilevered roof trusses in the world. This paper discusses the scope of the project, including the vibration analysis that was performed to generate artificial wind pressure time history, the SAP2000 analysis, a practice engineering TMD analysis, design and shop drawings, fabrication, installation and commissioning. The wind pressure time history analysis shows that the TMD systems efficiently reduce both vertical and horizontal vibrations of the roof when subject to a 100 year wind event. The frequency, damping factor and mass of fabricated TMD system matched the design requirement. These vertical TMD systems are the largest TMD system for a building to control wind vertical vibration in the world.
