Basic concepts

An arch is a soft compression form. It can span a large area by resolving forces into compressive stresses and, in turn eliminating tensile stresses. This is sometimes referred to as arch action.BOOK, Vaidyanathan, R, Structural Analysis, Volume 2, 2004, Laxmi Publications, US, 978-81-7008-584-3, 127,weblink Google Books, As the forces in the arch are carried to the ground, the arch will push outward at the base, called thrust. As the rise, or height of the arch decreases, the outward thrust increases.BOOK, Ambrose, James, Building Structures, 2012, John Wiley & Sons, Inc., Hoboken, NJ, 30, In order to maintain arch action and prevent the arch from collapsing, the thrust needs to be restrained, either with internal ties or external bracing, such as abutments.BOOK, Ambrose, James, Building Structures, 2012, John Wiley & Sons, Inc., Hoboken, NJ, 978-0-470-54260-6, 31,

Fixed vs hinged arch

File:Rossgrabenbruecke 01 09.jpg|thumbnail|Rossgraben bridge (Rüeggisberg) near Bern, Switzerland, showing the hinge at mid-span of this three-hinged arch.]]The most common true arch configurations are the fixed arch, the two-hinged arch, and the three-hinged arch.The fixed arch is most often used in reinforced concrete bridge and tunnel construction, where the spans are short. Because it is subject to additional internal stress caused by thermal expansion and contraction, this type of arch is considered to be statically indeterminate.The two-hinged arch is most often used to bridge long spans. This type of arch has pinned connections at the base. Unlike the fixed arch, the pinned base is able to rotate,WEB, Luebkeman, Chris H., Support and Connection Types,weblink Architectonics: The Science of Architecture,, 3 February 2013, no,weblink" title="">weblink 28 October 2012, allowing the structure to move freely and compensate for the thermal expansion and contraction caused by changes in outdoor temperature. However, this can result in additional stresses, so the two-hinged arch is also statically indeterminate, although not to the degree of the fixed arch.The three-hinged arch is not only hinged at its base, like the two-hinged arch, but at the mid-span as well. The additional connection at the mid-span allows the three-hinged arch to move in two opposite directions and compensate for any expansion and contraction. This type of arch is thus not subject to additional stress caused by thermal change. The three-hinged arch is therefore said to be statically determinate.BOOK, Reynolds, Charles E, Reynolds's Reinforced Concrete Designer's Handbook, 2008, Psychology Press, New York, 978-0-419-25820-9, 41,weblink Google Books, It is most often used for medium-span structures, such as large building roofs.Another advantage of the three-hinged arch is that the pinned bases are more easily developed than fixed ones, allowing for shallow, bearing-type foundations in medium-span structures. In the three-hinged arch, "thermal expansion and contraction of the arch will cause vertical movements at the peak pin joint but will have no appreciable effect on the bases," further simplifying the foundation design.

Arches can also be configured to produce vaults and arcades.Arches with a circular form, also referred to as rounded arches, were commonly employed by the builders of ancient, heavy masonry arches.BOOK, Ambrose, James, Building Structures, 2012, John Wiley & Sons, Inc., Hoboken, NJ, 978-0-470-54260-6, 32, Ancient Roman builders relied heavily on the rounded arch to span large, open areas. Several rounded arches placed in-line, end-to-end, form an arcade, such as the Roman aqueduct.BOOK, Oleson, John, The Oxford Handbook of Engineering and Technology in the Classical World, 2008, Oxford University Press, US, 978-0-19-518731-1, 299, Pointed arches were most often used by builders of Gothic-style architecture.BOOK, Crossley, Paul, Gothic Architecture, 2000, Yale University Press, New Haven, CT, 978-0-300-08799-4, 58,weblink Google Books, The advantage to using a pointed arch, rather than a circular one, is that the arch action produces less thrust at the base. This innovation allowed for taller and more closely spaced openings, typical of Gothic architecture.BOOK, Hadrovic, Ahmet, Structural Systems in Architecture, 2009, On Demand Publishing, 978-1-4392-5944-3, 289, WEB, MHHE, Structural Systems in Architecture,weblink, 3 February 2013, yes,weblink" title="">weblink 13 March 2013, File:Notre-dame-de-paris-vue-interieure-salle-nord.jpg|thumbnail|Interior vaulted ceiling of Notre Dame de Paris, showing the ribs at the intersection of several arches]]Vaults are essentially "adjacent arches [that] are assembled side by side." If vaults intersect, complex forms are produced with the intersections. The forms, along with the "strongly expressed ribs at the vault intersections, were dominant architectural features of Gothic cathedrals."The parabolic arch employs the principle that when weight is uniformly applied to an arch, the internal compression resulting from that weight will follow a parabolic profile. Of all arch types, the parabolic arch produces the most thrust at the base, but can span the largest areas. It is commonly used in bridge design, where long spans are needed.File:Tyne Bridge - Newcastle Upon Tyne - England - 2004-08-14.jpg|thumbnail|Tyne Bridge in Newcastle upon Tyne, (England]]: a parabolic arch used in bridge design)The catenary arch has a shape different from the parabolic curve. The shape of the curve traced by a loose span of chain or rope, the catenary is the structurally ideal shape for a freestanding arch of constant thickness.{{clear left}}Types of arches displayed chronologically, roughly in the order in which they were developed:File:Triangular arch.svg|Triangular archFile:Rundbåge.png|Round arch, or semi-circular archFile:Segmentbåge.png|Segmental arch is less than a semicircleFile:Stigande båge.png|Unequal round arch, or round archFile:Lansettbåge.png|Lancet archFile:Spetsbåge.png|Equilateral pointed archFile:Skulderbåge.png|Shouldered flat arch (see also: jack arch)File:Trepassbåge.png|Trefoil arch, or three-foiled cusped archFile:Hästskobåge.png|Horseshoe archFile:Korgbåge.png|Three-centered archFile:Ellipsbåge.png|Elliptical archFile:Draperibåge.png|Inflexed archFile:Ogee-shaped arch.svg|Ogee archFile:Karnisbåge.png|Reverse ogee archFile:Tudorbåge.png|Tudor archFile:Parabelbåge.png|Parabolic arch


True arches, as opposed to corbel arches, were known by a number of civilizations in the ancient Near East and the Levant, but their use was infrequent and mostly confined to underground structures, such as drains where the problem of lateral thrust is greatly diminished.{{harvnb|Rasch|1985|p=117}}An example of the latter would be the Nippur Arch.John P.

They also introduced the triumphal arch as a military monument. Vaults began to be used for roofing large interior spaces such as halls and temples, a function that was also assumed by domed structures from the 1st century BC onwards.The segmental arch was first built by the Romans who realized that an arch in a bridge did not have to be a semicircle,{{harvnb|Galliazzo|1995|pp=429–437}}{{harvnb|O'Connor|1993|p=171}} such as in Alconétar Bridge or Ponte San Lorenzo. They were also routinely used in house construction, as in Ostia Antica (see picture).In ancient China, most architecture was wooden, including the few known arch bridges from literature and one artistic depiction in stone-carved relief.Needham, Joseph (1986), Science and Civilization in China: Volume 4, Physics and Physical Technology, Part 3, Civil Engineering and Nautics, Taipei: Caves Books, pp. 161–188, {{ISBN|0-521-07060-0}}.Needham, Joseph (1986), Science and Civilisation in China: Volume 4, Physics and Physical Technology; Part 2, Mechanical Engineering, Taipei: Caves Books, pp. 171–172 {{ISBN|0-521-05803-1}}.Liu, Xujie (2002), "The Qin and Han dynasties", in Steinhardt, Nancy S., Chinese Architecture, New Haven: Yale University Press, p. 56, {{ISBN|0-300-09559-7}}.

However, the ancient Romans had virtually all of these components beforehand; for example, Trajan's Bridge had open spandrels built in wood on stone pillars.This title strictly applies only to the sum of attributes given (O’Connor, Colin: Roman Bridges, Cambridge University Press 1993, {{ISBN|0-521-39326-4}}, p. 171): Various Roman stone pillar bridges featured wooden open-spandrel segmental arches as early as the 2nd century CE, among them Trajan's bridge, the longest bridge of the world to have been built for over a thousand years. Also, a dozen or more Roman close-spandrel stone segmental arch bridges are known from the 1st century BC onwards, such as the Ponte San Lorenzo (Padua), Alconétar Bridge and the Makestos Bridge (Turkey), the last having half-open spandrels. The 27 segmental arches of the Bridge at Limyra (300 ce) feature span to rise ratios between 5.3 and 6.5 to 1, making it an earlier example of a stone quarter circle segmental arch bridge. This leaves the Anji bridge the title of "the oldest open-spandrel stone quarter circle segmental arch bridge in the world".File:Porte Caracalla - Tébessa باب كركلا - تبسة 3.jpg|thumb|Arch of Caracalla at ThevesteThevesteThe first example of an early Gothic arch in Europe is in Sicily in the Greek fortifications of Gela. The semicircular arch was followed in Europe by the pointed Gothic arch or ogive, whose centreline more closely follows the forces of compression and which is therefore stronger. The semicircular arch can be flattened to make an elliptical arch, as in the Ponte Santa Trinita. Parabolic arches were introduced in construction by the Spanish architect Antoni Gaudí, who admired the structural system of the Gothic style, but for the buttresses, which he termed "architectural crutches". The first examples of the pointed arch in the European architecture are in Sicily and date back to the Arab-Norman period.The horseshoe arch is based on the semicircular arch, but its lower ends are extended further round the circle until they start to converge. The first known built horseshoe arches are from the Kingdom of Aksum in modern-day Ethiopia and Eritrea, dating from ca. 3rd–4th century. This is around the same time as the earliest contemporary examples in Roman Syria, suggesting either an Aksumite or Syrian origin for the type.Stuart Munro-Hay, Aksum: A Civilization of Late Antiquity.

File:Pont d'arcades de Móra d'Ebre (Ribera d'Ebre, Catalonia).jpg|thumbnail|A series of parabolic arches on the Móra d'Ebre bridge, CataloniaCataloniaSince it is a pure compression form, the arch is useful because many building materials, including stone and unreinforced concrete, can resist compression, but are weak when tensile stress is applied to them.BOOK, Reid, Esmond, Understanding Buildings: A Multidisciplinary Approach, 1984, MIT Press, Cambridge, MA, 978-0-262-68054-7, 12,weblink no,weblink 2 June 2016, An arch is held in place by the weight of all of its members, making construction problematic. One answer is to build a frame (historically, of wood) which exactly follows the form of the underside of the arch. This is known as a centre or centring. Voussoirs are laid on it until the arch is complete and self-supporting. For an arch higher than head height, scaffolding would be required, so it could be combined with the arch support. Arches may fall when the frame is removed if design or construction has been faulty. The first attempt at the A85 bridge at Dalmally, Scotland suffered this fate, in the 1940s.{{Citation needed|date=February 2011}} The interior and lower line or curve of an arch is known as the intrados.Old arches sometimes need reinforcement due to decay of the keystones, forming what is known as bald arch.In reinforced concrete construction, the principle of the arch is used so as to benefit from the concrete's strength in resisting compressive stress. Where any other form of stress is raised, such as tensile or torsional stress, it has to be resisted by carefully placed reinforcement rods or fibres.BOOK, Allen, Edward, Fundamentals of Building Construction, 2009, John Wiley & Sons, Hoboken, NJ, 978-0-470-07468-8, 529,
