What architectural style is most prominent in Burj Khalifa?

The most prominent architectural style in Burj Khalifa is contemporary or modern architecture. It displays minimal ornamentation on the building’s surface and instead focuses on advanced structural engineering techniques and complex geometric forms. The building integrates modern architectural principles such as minimalism, efficiency, sustainability, and innovation in high-rise construction. It uses simple reflective glazing and lacks external projections, instead emphasizing the height and verticality of the structure. The smooth stainless steel spire at the building’s pinnacle is also a modern design feature. Burj Khalifa’s three-petal footprint draws inspiration from traditional Islamic architecture. 

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.
