Parabolic Arch
A parabolic arch is an arch in the shape of a parabola.Article about parabolic arch by The Free DictionaryParabolic arch , Article about parabolic arch by The Free Dictionary accessdate: March 2, 2017 In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms. Description The mathematics While a parabolic arch may resemble a catenary arch, a parabola is a quadratic function while a catenary is the hyperbolic cosine, , a sum of two exponential functions. One parabola is , and hyperbolic cosine is . The curves are unrelated. The line of thrust Unlike a catenary arch, the parabolic arch employs the principle that when weight is uniformly applied above, the internal compression (see line of thrust) resulting from that weight will follow a parabolic curve. Of all arch types, the parabolic arch produces the most thrust at the base. Also, it can span the widest area. It is commonly used in bridge desig ...

Taq Kasra
Tāq Kasrā ( ar, طاق كسرى, translit=ṭāq kisrā), also transcribed as ''Taq-i Kisra'' or ''Taq-e Kesra'' ( fa, طاق کسری, romanized: ''tâğe kasrâ'') or Ayvān-e Kesrā ( fa, ایوان خسرو, translit=Eivâne Xosrow, links=, meaning Iwan of Chosroes) are the remains of a Sasanian-era Persian monument, dated to c. the 3rd to 6th-century, which is sometimes called the Arch of Ctesiphon. It is located near the modern town of Salman Pak, Iraq. It is the only visible remaining structure of the ancient city of Ctesiphon. 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 Gavmishan Bridge. History The exact time of construction is not known with certainty. Some historians believe the founder is Shapur I who ruled Iran from 242 to 272 AD and some other believe that construction possibly began during the reign of Anushiruwan the Just (Khosrow I) after a c ...

Palau Güell
The Palau Güell (, en, Güell Palace) is a mansion designed by the architect Antoni Gaudí for the industrial tycoon Eusebi Güell, and was built between 1886 and 1888. It is situated on the Carrer Nou de la Rambla, in the El Raval neighborhood of Barcelona in Catalonia, Spain. It is part of the UNESCO World Heritage Site "Works of Antoni Gaudí". The home is centered around the main room for entertaining high society guests. Guests entered the home in horse-drawn carriages through the front iron gates, which featured a parabolic arch and intricate patterns of forged ironwork resembling seaweed and in some parts a horsewhip. Animals could be taken down a ramp and kept in the livery stable in the basement where the servants resided, while the guests went up the stairs to the receiving room. The ornate walls and ceilings of the receiving room disguised small viewing windows high on the walls where the owners of the home could view their guests from the upper floor and get a " ...

Oscar Niemeyer
Oscar Ribeiro de Almeida Niemeyer Soares Filho (15 December 1907 – 5 December 2012), known as Oscar Niemeyer (), was a Brazilian architect considered to be one of the key figures in the development of modern architecture. Niemeyer was best known for his design of civic buildings for Brasília, a planned city that became Brazil's capital in 1960, as well as his collaboration with other architects on the headquarters of the United Nations in New York. His exploration of the aesthetic possibilities of reinforced concrete was highly influential in the late 20th and early 21st centuries. Both lauded and criticized for being a "sculptor of monuments", Niemeyer was hailed as a great artist and one of the greatest architects of his generation by his supporters. He said his architecture was strongly influenced by Le Corbusier, but in an interview, assured that this "didn't prevent isarchitecture from going in a different direction".Salvaing, Matthieu (2002) ''Oscar Niemeye ...

Félix Candela
Félix Candela Outeriño (; January 27, 1910 – December 7, 1997) was a Spanish and Mexican architect who was born in Madrid and at the age of 26, emigrated to Mexico, acquiring double nationality. He is known for his significant role in the development of Mexican architecture and structural engineering. Candela's major contribution to architecture was the development of thin shells made out of reinforced concrete, popularly known as ''cascarones''. He was Santiago Calatrava's icon who has had a great influence on his works. Early life Felix Candela was born in Madrid, Spain in 1910. In 1927 Candela enrolled in La Escuela Superior de Arquitectura (Madrid Superior Technical School of Architecture), graduating in 1935; at which time Candela traveled to Germany to further study architecture. Early after he started classes, he developed a very keen sense of geometry and started teaching other students in private lessons. In his junior year, his visual intelligence and h ...

Hyperbolic Paraboloid
In geometry, a paraboloid is a quadric surface that has exactly one axis of symmetry and no center of symmetry. The term "paraboloid" is derived from parabola, which refers to a conic section that has a similar property of symmetry. Every plane section of a paraboloid by a plane parallel to the axis of symmetry is a parabola. The paraboloid is hyperbolic if every other plane section is either a hyperbola, or two crossing lines (in the case of a section by a tangent plane). The paraboloid is elliptic if every other nonempty plane section is either an ellipse, or a single point (in the case of a section by a tangent plane). A paraboloid is either elliptic or hyperbolic. Equivalently, a paraboloid may be defined as a quadric surface that is not a cylinder, and has an implicit equation whose part of degree two may be factored over the complex numbers into two different linear factors. The paraboloid is hyperbolic if the factors are real; elliptic if the factors are complex conju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sagrada Família
The Basílica i Temple Expiatori de la Sagrada Família, shortened as the Sagrada Família, is an unfinished church in the Eixample district of Barcelona, Catalonia, Spain. It is the largest unfinished Catholic church in the world. Designed by the Catalan architect Antoni Gaudí (1852–1926), his work on Sagrada Família is part of a UNESCO World Heritage Site. On 7 November 2010, Pope Benedict XVI consecrated the church and proclaimed it a minor basilica. On 19 March 1882, construction of the Sagrada Família began under architect Francisco de Paula del Villar. In 1883, when Villar resigned, Gaudí took over as chief architect, transforming the project with his architectural and engineering style, combining Gothic and curvilinear Art Nouveau forms. Gaudí devoted the remainder of his life to the project, and he is buried in the church's crypt. At the time of his death in 1926, less than a quarter of the project was complete. Relying solely on private donations, the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catenary Arches
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. 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 be a very scientific work. I have not yet had time to engage in it; but I find that the conclusions of his demonstrations are, that every part of the catenary is in perfect equilibrium". Structural properties Architecturally, a catenary arch has the ability to withstand the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antoni Gaudí
Antoni Gaudí i Cornet (; ; 25 June 1852 – 10 June 1926) was a Catalan architect from Spain known as the greatest exponent of Catalan Modernism. Gaudí's works have a highly individualized, ''sui generis'' style. Most are located in Barcelona, including his main work, the church of the Sagrada Família. Gaudí's work was influenced by his passions in life: architecture, nature, and religion. He considered every detail of his creations and integrated into his architecture such crafts as ceramics, stained glass, wrought ironwork forging and carpentry. He also introduced new techniques in the treatment of materials, such as '' trencadís'' which used waste ceramic pieces. Under the influence of neo-Gothic art and Oriental techniques, Gaudí became part of the ''Modernista'' movement which was reaching its peak in the late 19th and early 20th centuries. His work transcended mainstream ''Modernisme'', culminating in an organic style inspired by natural forms. Gaudí rarely dr ...

Clochán
A clochán (plural clocháin) or beehive hut is a dry-stone hut with a corbelled roof, commonly associated with the south-western Irish seaboard. The precise construction date of most of these structures is unknown with the buildings belonging to a long-established Celtic tradition, though there is at present no direct evidence to date the surviving examples before . Some associated with religious sites may be pre-Romanesque, some consider that the most fully intact structures date after the 12th century or later. It is where monks lived. Form They are most commonly round beehive huts, but rectangular plans are known as well. It has been suggested that the rectangular footprints date to a later era. Some clochán are not completely built of stone and may have possessed a thatched roof. The walls are very thick, up to . Sometimes several clochans are joined together by their walls. Locations Clochán are mainly found in the Southwest of Ireland, for example at Skellig Michae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
