What structural engineering principles are employed in the construction of Burj Khalifa?
The Burj Khalifa used several structural engineering techniques to support its record-setting height. Firstly, the robust buttressed core structural system. The tower has a hexagonal central reinforced concrete core that provides stability. This core is bolstered by three wings with their concrete cores and perimeter columns. As the building height increases, the wings are set back in a spiraling pattern. This allows the building shape to change at each tier, reducing wind forces. Secondly, setting back the branches enabled the construction of one of the world’s tallest reinforced concrete buildings. The spiral design showcases the modernity of Burj Khalifa’s form.
Lastly, high-performance concrete was explicitly developed for Burj Khalifa, allowing quicker construction. As concrete cures, it releases heat, which can cause cracking, so cooling pipes are embedded in the concrete mix. The central core emerges at the top and transitions into a structural spire. The spire uses a diagonally braced lateral system and reinforced concrete main shaft. The spire was assembled inside the building and jacked to its full height of over 700 feet (213 meters) using a hydraulic pump system.
Who designed the Burj Khalifa?
The Burj Khalifa was designed by the architectural firm Skidmore, Owings, and Merrill LLP (SOM), which has pioneered the world’s tallest buildings. The specific architects were Adrian Smith, the chief architect who handled the overall building design, and George Efstathiou, the project designer. The structural engineering partner was William F. Baker. The initial conceptual design was by Adrian Smith based on the client’s request for a record-setting tall structure. Smith had previously worked on many supertall buildings at SOM. His experience enabled the creation of the tri-lobed Y-shaped plan, which resists wind forces.
Smith moved to his firm during construction and was replaced as chief architect by George Efstathiou in 2006. So, while Adrian Smith’s conceptual designs were crucial, Efstathiou oversaw the tower’s later technical development and completion. Structural engineer Bill Baker helped realize the buttressed core structural scheme enabling the tower’s height.
