Buttressed core


Buttressed core is a structural system for high buildings, consisting of a hexagonal core reinforced by three buttresses that form a Y shape.

Properties

The buttressed core supports itself both laterally and torsionally. It also eliminates the need for column transfers, and moves loads in a smooth path from the building's top into its foundations.

Origin

The buttressed core was invented by the Skidmore, Owings & Merrill engineer
Bill Baker.
It was first used in Tower Palace III in Seoul but its ability to support higher buildings than ever before was first demonstrated in Burj Khalifa in Dubai.
