The term "skyscraper" was first applied to buildings of steel-framed construction of at least 10 storeys in the late 19th century, a result of public amazement at the tall buildings being built in major American cities like Chicago, New York City, Philadelphia, Detroit, and St. īy some measures, what came to be known as a "skyscraper" first appeared in Chicago with the 1885 completion of the world's first largely steel-frame structure, the Home Insurance Building. To appear more slender, allow less wind exposure and transmit more daylight to the ground, many skyscrapers have a design with setbacks, which in some cases is also structurally required.Īs of February 2022, fourteen cities in the world have more than 100 skyscrapers that are 150 m (492 ft) or taller: Hong Kong with 518 skyscrapers Shenzhen, China with 343 skyscrapers New York City, USA with 300 skyscrapers Dubai, UAE with 237 skyscrapers Mumbai, India with 208 skyscrapers Shanghai, China with 180 skyscrapers Tokyo, Japan with 165 skyscrapers Guangzhou, China with 152 skyscrapers Kuala Lumpur, Malaysia with 148 skyscrapers Chongqing, China with 135 skyscrapers Chicago, United States with 135 skyscrapers Wuhan, China with 109 skyscrapers Bangkok, Thailand with 108 skyscrapers and Jakarta, Indonesia with 108 skyscrapers.
Modern skyscrapers often have a tubular structure, and are designed to act like a hollow cylinder to resist wind, seismic, and other lateral loads. However, skyscrapers can have curtain walls that mimic conventional walls with a small surface area of windows.
#SKYSCRAPER CAST WINDOWS#
Modern skyscrapers' walls are not load-bearing, and most skyscrapers are characterised by large surface areas of windows made possible by steel frames and curtain walls. Some early skyscrapers have a steel frame that enables the construction of load-bearing walls taller than of those made of reinforced concrete. These curtain walls either bear on the framework below or are suspended from the framework above, rather than resting on load-bearing walls of conventional construction. One common feature of skyscrapers is having a steel frame that supports curtain walls. Skyscrapers may host offices, hotels, residential spaces, and retail spaces. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers are very tall high-rise buildings. Modern sources currently define skyscrapers as being at least 100 metres (330 ft) or 150 metres (490 ft) in height, though there is no universally accepted definition. The setbacks at various heights are a typical skyscraper feature.Ī skyscraper is a tall continuously habitable building having multiple floors. Completed in 2009, the Burj Khalifa, in Dubai, United Arab Emirates, is currently the tallest building in the world, with a height of 829.8 metres (2,722 ft).
