A megastructure is a very large manmade object, though the limits of precisely how large this is vary considerably. Some apply the term to any especially large or tall building. Some sources define a megastructure as an enormous self-supporting artificial construct. Other criteria such as rigidity or contiguousness are sometimes also applied, so large clusters of associated smaller structures may or may not qualify. The products of megascale engineering or astroengineering are megastructures.

  • Se le llama megaestructura a cualquier construcción artificial de proporciones gigantescas, propia de la ingeniería de megaescala. Este tipo de estructuras son descritas con medidas de cientos de kilómetros, en al menos una dimensión, y no es inhabitual que sean estructuras espaciales de algún tipo. (es)
  • A megastructure is a very large manmade object, though the limits of precisely how large this is vary considerably. Some apply the term to any especially large or tall building. Some sources define a megastructure as an enormous self-supporting artificial construct. Other criteria such as rigidity or contiguousness are sometimes also applied, so large clusters of associated smaller structures may or may not qualify. The products of megascale engineering or astroengineering are megastructures. Most megastructure designs could not be constructed with today's level of industrial technology. This makes their design examples of speculative (or exploratory) engineering. Those that could be constructed easily qualify as megaprojects. Megastructures are also an architectural concept popularized in the 1960s where a city could be encased in a single building, or a relatively small number of buildings interconnected. Such arcology concepts are popular in science fiction. Megastructures often play a part in the plot or setting of science fiction movies and books, such as Rendezvous with Rama by Arthur C. Clarke. In 1968, Ralph Wilcoxon defined a megastructure as any structural framework into which rooms, houses, or other small buildings can later be installed, uninstalled, and replaced; and which is capable of "unlimited" extension.Many architects have designed such megastructures. Some of the more notable such architects and architectural groups include the Metabolist Movement, Archigram, Cedric Price, Frei Otto, Constant Nieuwenhuys, Yona Friedman, and Buckminster Fuller.This type of framework allows the structure to adapt to the individual wishes of its residents, even as those wishes change with time. Other sources define a megastructure as "any development in which residential densities are able to support services and facilities essential for the development to become a self-contained community".

  • En science-fiction et ingénierie spéculative (ou exploratoire), une mégastructure est une énorme construction artificielle autosuffisante. La définition est plutôt informelle et varie selon les sources, mais exige généralement au moins que les dimensions soient dans les centaines de kilomètres. D'autres critères tels que la rigidité ou la contiguïté sont également parfois appliqués, et des ensembles de plus petites structures associées peuvent ou non être qualifiés. Les produits de l’ingénierie mégascalaire ou de l’astro-ingénierie sont des mégastructures. Les mégastructures sont également un concept architectural popularisé dans les années 1960 où une ville pouvait être contenue dans un bâtiment simple, ou un nombre relativement petits de bâtiments reliés ensemble. Techniquement parlant, une œcumenopole se rapporte a une mégastructure par son universalité et son auto-suffisance. Les mégastructures jouent souvent un rôle dans les scénarios des films et les livres de science-fiction. (fr)
  • Una megastruttura è una costruzione artificiale di enormi dimensioni; in particolare è stata descritta come un vasto complesso che integra varie funzioni tipiche di una città in un contesto solitamente ad alta densità abitativa. Il concetto è inizialmente divenuto popolare nell'ambito della fantascienza: in molte opere fantascientifiche, infatti, vengono rappresentate strutture di dimensioni di centinaia di chilometri in almeno una direzione; spesso si tratta di un qualche genere di oggetti spaziali abitati. Il termine, usato soprattutto dalla fine degli anni sessanta, ha finito per indicare qualsiasi struttura di grandi dimensioni, molte delle quali effettivamente costruite in tutto il mondo, in particolare grattacieli alti alcune centinaia di metri e ponti lunghi diversi chilometri. Non mancano tuttavia strutture ingegneristiche come alcuni degli ottovolanti, anche detti Montagne Russe, più grandi del mondo e le grandi centrali ad energia solare che si sviluppano per diverse decine di chilometri quadrati nei deserti americani. Un enorme edificio sufficiente a mantenere un'ecologia interna e una densità abitativa estremamente alta è detto più specificamente arcologia. (it)
