Macalloy Tie Bars in Washington Office Building
Year of Completion 2009
Macalloy tie bars have been used throughout this glass atrium. The tie rods are used as structural support for the glass façade, to suspend skybridges, to support a sculpture and as general bracing support.
The use of Macalloy tension bars allowed for a consistent look, utilizing the same fork, or clevis end, fitting throughout the building.
Springs were used within the façade to help control potential movement in the building.
