The Burj Khalifa [a] (known as the Burj Dubai prior to its inauguration) is a skyscraper in Dubai, United Arab Emirates and the world's tallest structure.With a total height of 829.8 m (2,722 ft, or just over half a mile) and a roof height (excluding antenna, but including a 242.6 m spire) [2] of 828 m (2,717 ft), the Burj Khalifa has been the tallest structure and building in the world since ...
The tallest structure in the world is the Burj Khalifa skyscraper at 828 m (2,717 ft). Listed are guyed masts (such as telecommunication masts), self-supporting towers (such as the CN Tower), skyscrapers (such as the Willis Tower), oil platforms, electricity transmission towers, and bridge support towers. This list is organized by absolute height.
The strong influence of tube structure design is also evident in the construction of the current tallest skyscraper, the Burj Khalifa, [49] which uses a Buttressed core. [70] Trussed tube and X-bracing: Changes of structure with height; the tubular systems are fundamental for supertall buildings.
The world's tallest human-made structure is the 828-metre-tall (2,717 ft) Burj Khalifa in Dubai, United Arab Emirates.The building gained the official title of "tallest building in the world" and the tallest self-supported structure at its opening on January 9, 2010.
For example, the depth of the pit that holds the substructure has to reach all the way to bedrock. If bedrock lies close to the surface, the soil on top of the bedrock is removed, and enough of the bedrock surface is removed to form a smooth platform on which to construct the building's foundation.

However, the Burj Khalifa surpassed Taipei 101 in 2010. [11] The construction of Taipei 101 was a joint venture led by Kumagai Gumi, a Japanese construction company, in cooperation with Samsung C&T of South Korea. Upon completion, it became the world's first skyscraper to exceed a height of half a kilometer (about 0.3 miles).
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 ...
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.
