Saddle Roof
A saddle roof is a roof form which follows a convex curve about one axis and a concave curve about the other. The hyperbolic paraboloid form has been used for roofs at various times since it is easily constructed from straight sections of lumber, steel, or other conventional materials. The term is used because the form resembles the shape of a saddle. Sometimes referred to as a hypar, the saddle roof may also be formed as a tensegrity structure. Mathematically, a saddle shape contains at least one saddle point. The historical meaning is a synonym for a gable roof particularly a ''dual-pitched'' roof on a tower, also called a ''pack-saddle roof''.Passmore, Augustine C.. "Saddle Roof".

Warszawa Ochota Railway Station
Warsaw Ochota ( pl, Warszawa Ochota) is a railway station in Warsaw, Poland, located in the district of Ochota at Plac Zawiszy on the corner of Aleje Jerozolimskie and Towarowa Street. The station lies in a cutting. It has two island platforms, one on the suburban tracks of the Warsaw Cross-City Line for the regional trains run by Koleje Mazowieckie and Szybka Kolej Miejska and one for the Warszawska Kolej Dojazdowa light railway. The station building, at the street level, was constructed in 1963: it has a saddle roof in a distinct shape of a hyperbolic paraboloid. It was including escalator then.Średnicowa 1946–1976. "AR/PS.

List Of Hyperboloid Structures
This page is a list of hyperboloid structures. These were first applied in architecture by Russian engineer Vladimir Shukhov (1853–1939). Shukhov built his first example as a water tower (hyperbolic shell) for the 1896 All-Russian Exposition. Subsequently, more have been designed by other architects, including Le Corbusier, Antoni Gaudí, Eduardo Torroja, Oscar Niemeyer and Ieoh Ming Pei. The shapes are doubly ruled surfaces, which can be classed as: * Hyperbolic paraboloids, such as saddle roofs * Hyperboloid of one sheet, such as cooling towers Image:Ruled hyperboloid.jpg, A hyperboloid of one sheet is a doubly ruled surface, and it may be generated by either of two families of straight lines.

Hyperboloid Structure
Hyperboloid structures are architectural structures designed using a hyperboloid in one sheet. Often these are tall structures, such as towers, where the hyperboloid geometry's structural strength is used to support an object high above the ground. Hyperboloid geometry is often used for decorative effect as well as structural economy. The first hyperboloid structures were built by Russian engineer Vladimir Shukhov (1853–1939), including the Shukhov Tower in Polibino, Dankovsky District, Lipetsk Oblast, Russia. Properties Hyperbolic structures have a negative Gaussian curvature, meaning they curve inward rather than curving outward or being straight. As doubly ruled surfaces, they can be made with a lattice of straight beams, hence are easier to build than curved surfaces that do not have a ruling and must instead be built with curved beams. Hyperboloid structures are superior in stability against outside forces compared with "straight" buildings, but have shapes often crea ...

Cathedral Of Saint Mary Of The Assumption (San Francisco, California)
The Cathedral of Saint Mary of the Assumption, also known locally as Saint Mary's Cathedral, is the principal church of the Roman Catholic Archdiocese of San Francisco in San Francisco, California. It is the mother church of the Catholic faithful in the California counties of Marin, San Francisco and San Mateo and is the metropolitan cathedral for the Ecclesiastical province of San Francisco. The cathedral is located in the Cathedral Hill neighborhood of San Francisco. The present cathedral replaced one (1891–1962) of the same name. The original Cathedral of Saint Mary of the Immaculate Conception was built in 1853–1854 and still stands today. It is now known as Old Saint Mary's Cathedral. Second cathedral In 1883, Archbishop Patrick W. Riordan purchased the northwest corner of Van Ness Avenue and O'Farrell Street in Western Addition. Riordan broke ground in December 1885. On May 1, 1887, the archbishop placed the cornerstone. Archbishop Riordan dedicated the edifice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Wales
Wales ( cy, Cymru ) is a country that is part of the United Kingdom. It is bordered by England to the east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of .

The country lies within the north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The conquest of Wales by Edward I of England was completed by 1283, though Owain Glyndŵr led the Welsh Revolt against English rule in the early 15th century, and briefly re-establis ...
