This geographical transition is accompanied by a change in approach to skyscraper design. However, the geographical domination ended when Petronas Twin Towers (Kuala Lumpur, Malaysia) were built in 1998 as world tallest buildings, marking the beginning of Asia reign in world tallest (next tallest was then Taipei 101 and finally current world tallest, Burj Khalifa, Dubai). The skyscraper, in name and social function, is a modern expression of the age-old symbol of the world center or axis mundi: a pillar that connects earth to heaven and the four compass directions to one another.Ĭompetition for taller buildings, and even race for the tallest began on the West, from cities of skyscrapers’ birth (Chicago and New York City) as early as from 1900s till 1990s for almost a century. The word skyscraper often carries a connotation of pride and achievement. Note that this criterion fits not only high rises but some other tall structures, such as towers. The Emporis Standards Committee defines a high-rise building as “a multi-story structure between 35-100 meters tall, or a building of unknown height from 12-39 floors” and a skyscraper as “a multi-story building whose architectural height is at least 100 meters.” Some structural engineers define a highrise as any vertical construction for which wind is a more significant load factor than earthquake or weight. The somewhat arbitrary term skyscraper should not be confused with the also ill-defined term high-rise. Shorter buildings are still sometimes referred to as skyscrapers if they appear to dominate their surroundings. A skyscraper taller than 300 meters (~1000 ft) may be referred to as supertall. Today, however, many of the tallest skyscrapers are built almost entirely with reinforced concrete.Ī loose convention in the United States and Europe now draws the lower limit of a skyscraper at 150 meters (~500 ft). The steel frame developed in stages of increasing self-sufficiency, with several buildings in Chicago and New York advancing the technology that allowed the steel frame to carry a building on its own. This definition was based on the steel skeleton-as opposed to constructions of load-bearing masonry, which passed their practical limit in 1891 with Chicago’s Monadnock Building. The structural definition of the word skyscraper was refined later by architectural historians, based on engineering developments of the 1880s that had enabled construction of tall multi-storey buildings. More recent arguments point to New York’s seven floor Equitable Life Assurance Building built in 1870 and it was arguably the first office building built using a kind of skeletal frame but it depends on what factors are chosen and even the scholars making the argument find it academic. The first skyscraper was for many years thought to be the Home Insurance Building built in Chicago, Illinois in 1885. The term was first applied to buildings in the late 19th century as a result of public amazement at the tall buildings being built in Chicago and New York City. The word “skyscraper” originally was a nautical term referring to a small triangular sail set above the skysail on a sailing ship. Hence, even a building of only 80 metres tall can be considered a skyscraper if it protrudes above the existing built environment and changes the overall skyline. Most cities define the term ‘skyscraper’ empirically. Everyone will refer it to as structure that is tall (but how tall it should be to be classified as skyscraper?) Arguments and debates came here, which involved many parties and corporations like Council on Tall Buildings and Urban Habitat (CTBUH – responsible mainly in listing official world tallest buildings list), Emporis Standards Committee, etc.
There is actually no clear or exact definition of ‘skyscraper’. Hence, it’s time to get back a little bit to skyscraper on this blog once again. Recently, it seems that I had abandoned my habit of loving skyscrapers due to busy days with typical architecture of modern houses and public buildings of multi-purpose. Everyone who is no stranger to me definitely knows that I’m quite a big fan of skyscraper, not mainly because it is tall, but its presence that dominates the surrounding built environment and symbolises a vision of reaching up to the sky.
