Overview
Walter P Moore provided structural engineering for Alina at 1072 West Peachtree, a 61-story mixed-use tower in Midtown Atlanta. The project combines residential, office, parking, and amenity spaces within a highly efficient structural system that responds to significant wind demands and differing program requirements. Strategic use of sloped columns eliminated the need for a costly transfer level while supporting long-span office and parking spaces below.

About the project
The tower includes 40 stories of apartments over a 12-story office block over an 8-story parking podium. Amenities are located at the top of the parking block and office block.
One major feature of the tower structure is the use of sloped columns. Sloped columns are used to transition the column grid from the residential portion of the tower to a long-span column grid within the office and parking blocks. This strategy eliminated the need for a multi-million dollar transfer level within the tower.
Towers of this height must resist extremely high wind loads in order to reduce sway, and a core wall system by itself is insufficient. Various lateral system options were studied, based on two key criteria: which structural system has both the least cost and the small structural member sizes. Ultimately the optimal structural system selected was a dual-system which includes the central concrete core plus concrete outrigger walls in the East/West direction. The outrigger walls are located mid-height up the residential portion of the tower.
