Structural Design

-Reinforced Concrete structure with high performance concrete core.

-Building is in a general Y shape.  Each leg steps down in a spiral stepping pattern to avoid built-up of wind vortices.

- Structural system includes a hexagonal hub at center that is enhanced with high performance concrete core and perimeter columns at each wing.

- The structure is extreme stiff laterally and torsionally.
