The Burj Khalifa, the tallest structure in the world at 828 meters, exemplifies groundbreaking structural engineering. The building employs a buttressed core system, where a hexagonal central core is supported by three wings that act as buttresses. This innovative system ensures unparalleled stability against wind and seismic forces, critical for a structure of this height. High-strength concrete and steel were used strategically to reduce material usage while maintaining rigidity. The tapering form of the tower also minimizes wind forces, while its foundation is supported by reinforced concrete piles extending over 50 meters into the ground. The project demonstrates how engineering innovation and material efficiency can be combined to achieve record-breaking heights.
