The use of structural glass elements increases the freedom of highly transparent glass architecture tremendously. Next to the use of jumbo-sized glasses, the connection methodology is the key design driver to achieve maximum transparency and seamless appearance.
The case study of the Levitation Ledges at the Summit of the One Vanderbilt Tower discusses design development, engineering, testing and installation of the structural glass structure with its minimalist connections: A novel mortise and tenon joint based on mechanical locking is combined with classic structural glazing and bolted connections.
The Levitation Ledges in 300m height above ground aim to create a pure perception of Manhattan’s skyline and a thrilling place to be. They are part of an observation deck providing a holistic interactive experience.
