He is best known as the engineer of Burj Khalifa (Dubai, 2009), the world's tallest man-made structure. To support the tower's record heights, he developed the "buttressed core" [2] structural system, consisting of a hexagonal core reinforced by three buttresses that form a Y shape. This innovative system allows the structure to support itself ...

For example, the Burj Khalifa, the world's tallest building as well as the world's tallest structure, uses specially treated and mixed reinforced concrete. Over 45,000 cubic metres (59,000 cu yd) of concrete, weighing more than 110,000 t (120,000 short tons) were used to construct the concrete and steel foundation, which features 192 piles ...
Fazlur Khan and J. Rankine defined the framed tube structure as "a three dimensional space structure composed of three, four, or possibly more frames, braced frames, or shear walls, joined at or near their edges to form a vertical tube-like structural system capable of resisting lateral forces in any direction by cantilevering from the foundation."
This system has been adapted and is still used today for some of the world's most recent tallest buildings, including the 828-meter-tall Burj Khalifa, designed by SOM and completed in 2010. In the 1960s and 1970s, SOM was an early leader in computer-aided design, developing in-house digital tools that preceded the CAD systems used widely today.
