Project Description

Milman & Associates investigated the nature of numerous cracks and an excessive level of vibration in the departure floor of Terminal 3 at Toronto’s Pearson airport. The team analyzed the complex, dynamic and static structural behaviour of the floor system with respect to strength, deflection and vibration, and conducted a dynamic test on the floor in order to determine its dynamic properties. To mitigate the overabundance of departure floor vibrations, our team, in collaboration with Swallow Acoustics, developed a system of tuned mass dampers (TMD) that have been installed under one section of structural frame of Terminal 3’s departure floor. The project for complete rehabilitation of a Departure floor structure is underway and will be complete in 2016.
