Nubian Vaults
In architecture, a Nubian vault is a type of curved surface forming a Vault (architecture), vaulted structure. The mudbrick structure was revived by Egyptian architect Hassan Fathy after re-discovering the technique in the Nubian village of Abu al-Riche. The technology is advocated by environmentalists as environmentally friendly and sustainable since it makes use of pure earth without the need of timber.Swan, Simon''Elegant Solutions'' Saudi Aramco World, July/August 1999, Volume 50, Number 4. The technology is of Nubians, Nubian origin. One of the key advantages of the Nubian vault is that it can be built without any support or shuttering. The earth bricks are laid leaning at a slight slope against the gable walls in a length-wise vault, as in this photo of a building from the ruins of Ayn Asil in Egypt. The same principle can be used to build domes, as in the example below from Cameroon. The age-old Nubian vault technique was notably revived by the Egyptian architect Hassan Fa ...

Arches And Vaults
An arch is a curved vertical structure span (engineering), spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century Anno Domini, BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of Vault (architecture), vaults, with the barrel vault in particular being a continuous arch. Extensive use of arches and vaults characterizes an arcuated construction, as opposed to the trabeated system, where, like in the architectures of ancient Greece, China, and Japan (as well as the modern steel-framed technique), Post and lintel, posts and beams dominate. Arches had several advantages over the lintel, especially in the masonr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taq Kasra
Tāq Kasrā (), also transcribed as ''Taq-i Kisra'' or ''Taq-e Kesra'' (, romanized: ''tâğe kasrâ'') or Ayvān-e Kesrā (, meaning Iwan of Khosrow) are the remains of a Sasanian-era Persian monument, dated to c. the 3rd to 6th centuries, which is sometimes called the Arch of Ctesiphon. It is located near the modern town of Salman Pak, Iraq. It was the facade of the main palace in Ctesiphon, and is the only visible remaining structure of the ancient capital city. The archway is considered a landmark in the history of architecture, and is the second largest single-span vault of unreinforced brickwork in the world after the Gavmishan Bridge in Iran. History The exact time of the structure's construction is not known with certainty. Some historians believe it was constructed under Shapur I who ruled Sassanian Persia from 242 to 272 AD and some other believe that construction possibly began during the reign of Anushiruwan the Just (Khosrow I) after a campaign against the B ...

Catenary
In physics and geometry, a catenary ( , ) is the curve that an idealized hanging chain or wire rope, cable assumes under its own weight when supported only at its ends in a uniform gravitational field. The catenary curve has a U-like shape, superficially similar in appearance to a parabola, which it is not. The curve appears in the design of certain types of Catenary arch, arches and as a cross section of the catenoid—the shape assumed by a soap film bounded by two parallel circular rings. The catenary is also called the alysoid, chainette,#MathWorld, MathWorld or, particularly in the materials sciences, an example of a funicular curve, funicular. Rope statics describes catenaries in a classic statics problem involving a hanging rope. Mathematically, the catenary curve is the Graph of a function, graph of the hyperbolic cosine function. The surface of revolution of the catenary curve, the catenoid, is a minimal surface, specifically a minimal surface of revolution. A ha ...

Catenary Arch
A catenary arch is a type of architectural arch that follows an inverted catenary curve. The catenary curve has been employed in buildings since ancient times. It forms an underlying principle to the overall system of vaults and buttresses in stone vaulted Gothic cathedrals and in Renaissance domes. It is not a parabolic arch, although the non- circumferential curves used in arch designs (parabola, catenary, and weighted catenary) look similar, and match at shallow profiles, so a catenary is often misclassified as a parabola (per Galileo, "the angingchain fits its parabola almost perfectly"). In history The 17th-century scientist Robert Hooke wrote: "''Ut pendet continuum flexile, sic stabit contiguum rigidum inversum''", or, "As hangs a flexible cable so, inverted, stand the touching pieces of an arch." A note written by Thomas Jefferson in 1788 reads, "I have lately received from Italy a treatise on the equilibrium of arches, by the Abbé Mascheroni. It appears to b ...

List Of Architectural Vaults
The following is a list of arched structures known in architecture as Vault (architecture), vaults. * Annular vault – A Barrel vault springing from two concentric walls. * Barrel vault – An architecture tunnel vault or barrel vault is a semicircular arch extended in depth: a continuous series of arches, one behind the other. The simplest form of an architecture vault, consisting of a continuous surface of semicircular or pointed sections. It resembles a barrel or tunnel which has been cut in half lengthwise and is known as tunnel vault or wagon vault. A longitudinal barrel vault is a barrel (or tunnel) vault which follows the main longitudinal direction of the nave. Usually when a vault is referred to simply as a barrel (or tunnel) vault, it may be assumed to be a longitudinal barrel vault. * Baroque vault – term from Church of Our Lady in front of Týn.

Nubian Architecture
Nubian architecture is diverse and ancient. Temporary or seasonal settlements have been found in Nubia dating from circa 6000 BC. These villages were roughly contemporary with the walled town of Jericho in Palestine. Early Period The earliest Nubian architecture used perishable materials, wattle and daub, mudbricks, animal hide, and other light and supple materials. Early Nubian architecture consisted of speos, structures derived from the carving of rock, an innovation of the A-Group culture (c. 3800-3100 BCE), as seen in the Sofala Cave Rock-cut architecture, rock-cut temple. Much later rock-cut tombs include the burial chambers of the Kushite monarchs at El Kurru, dating from 860-650 BC. Other later examples of rock cut architecture in Nubia include the temples of Beit Wali, Gerf Hussein, Temple of Derr, Temple of Mut and temple of Amada built during the New Kingdom of Egypt, New Kingdom when Nubia was ruled by Egypt. Two types of A-Group graves exist. One was oval in shape de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kurna
Kurna (also Gourna, Gurna, Qurna, Qurnah or Qurneh; ) is a group of three closely related villages (New Qurna, Qurna and Sheikh Abd el-Qurna) located on the West Bank of the River Nile opposite the modern city of Luxor in Egypt near the Theban Hills. New Qurna was designed and built in the late 1940s and early 1950s by Egyptian architect Hassan Fathy to house people living in Qurna which is now uninhabited. New Qurna was added to the 2010 World Monuments Watch List of Most Endangered Sites to bring attention to the site's importance to modern town planning and vernacular architecture due to the loss of much of the original form of the village since it was built. Historical use of the name Qurna The name Kurna signifies "a promontory" or "a point of a mountain". Émile Amélineau identifies it with ancient Pekolol (). The name Gourna is first mentioned by Protais and Charles François d'Orléans, two Order of Friars Minor Capuchin, Capuchin missionary brothers travelling in Upper ...

Architecture
Architecture is the art and technique of designing and building, as distinguished from the skills associated with construction. It is both the process and the product of sketching, conceiving, planning, designing, and construction, constructing buildings or other Structure#Load-bearing, structures. The term comes ; ; . Architectural works, in the material form of buildings, are often perceived as cultural symbols and as work of art, works of art. Historical civilizations are often identified with their surviving architectural achievements. The practice, which began in the Prehistory, prehistoric era, has been used as a way of expressing culture by civilizations on all seven continents. For this reason, architecture is considered to be a form of art. Texts on architecture have been written since ancient times.
