tallest buildings in the world

tallest buildings in the world, the highest-standing buildings on the globe, as determined by the Council on Tall Buildings and Urban Habitat (CTBUH), an international nonprofit organization headquartered in Chicago. The CTBUH recognizes a tall building as having 14 or more stories and standing more than 50 meters (165 feet) tall.

The development of tall buildings in the late 18th century came as a result of the coincidence of several technological and social developments. These developments included the installation of the first safe passenger elevator (in the Haughwout Department Store, New York City) in 1857, the use of a cast-iron and wrought-iron framework to support the weight of upper floors, and the refinement of the Bessemer process, first used in the United States in the 1860s, which allowed for the major advance in skyscraper construction. As steel is stronger and lighter than iron, the use of a steel frame made possible the construction of truly tall buildings. Further refinements in the late 20th and early 21st centuries in engineering, materials, and other technologies allowed for even greater construction heights, resulting in buildings that far surpass 14 stories or more. The engineers of the Burj Khalifa, Dubai, for example, used a buttressed core, a kind of concrete spine that runs through an entire structure, to build the tallest building in the world. The list below offers an introduction to a few of the other tallest buildings in the world, many of which have been built in the 21st century in Asia and the Middle East, where construction costs tend to be lower than in other parts of the globe.
