A cantilever skyscraper is a building with upper floors that project horizontally beyond the footprint of the lower floors. This is achieved by using cantilevers, which are beams that extend horizontally from a vertical support and are only supported on one end. Cantilever skyscrapers are often used to create more space on lower floors, as the upper floors do not need to be directly above the lower floors.
Cantilever skyscrapers offer several benefits. They can create more open space on lower floors, which can be used for public spaces, retail, or other purposes. They can also provide better views from upper floors, as the upper floors are not obstructed by lower floors. Cantilever skyscrapers can also be more structurally efficient than traditional skyscrapers, as the cantilevers can help to distribute the weight of the building more evenly.
The first cantilever skyscraper was built in 1891 in Chicago, Illinois. Since then, cantilever skyscrapers have been built all over the world, including the Empire State Building in New York City, the Willis Tower in Chicago, and the Burj Khalifa in Dubai. Cantilever skyscrapers are a popular choice for architects and engineers because they offer a unique and efficient way to create tall buildings.
