Voussoirs
A voussoir () is a wedge-shaped element, typically a stone, which is used in building an arch or vault. Although each unit in an arch or vault is a voussoir, two units are of distinct functional importance: the keystone and the springer. The keystone is the centre stone or masonry unit at the apex of an arch. The springer is the lowest voussoir on each side, located where the curve of the arch springs from the vertical support or abutment of the wall or pier. The keystone is often decorated or enlarged. An enlarged and sometimes slightly dropped keystone is often found in Mannerist arches of the 16th century, beginning with the works of Giulio Romano, who also began the fashion for using voussoirs above rectangular openings, rather than a lintel (Palazzo Stati Maccarani, Rome, circa 1522). The word is a stonemason's term borrowed in Middle English from French verbs connoting a "turn" ('' OED''). Each wedge-shaped voussoir ''turns aside'' the thrust of the mass above, tr ...

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction.

Masonry
Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term ''masonry'' can also refer to the units themselves. The common materials of masonry construction are bricks, building stone such as marble, granite, and limestone, cast stone, concrete blocks, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction trades. Applications Masonry is commonly used for walls and buildings. Brick and concrete block are the most common types of masonry in use in industrialized nations and may be either load-bearing or non-load-bearing. Concrete blocks, especially those with hollow cores, offer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arches And Vaults
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Falsework
Falsework consists of temporary structures used in construction to support a permanent structure until its construction is sufficiently advanced to support itself. For arches, this is specifically called centering. Falsework includes temporary support structures for formwork used to mold concreteHardie G.M. (1995) Building Construction: Principles, Practices, and Materials. New Jersey: Prentice Hall. (Pg 116, paragraph 1) in the construction of buildings, bridges, and elevated roadways. The British Standards of practice for falsework, BS 5975:2008, defines falsework as "Any temporary structure used to support a permanent structure while it is not self-supporting." History Falsework has been employed in bridge and viaduct construction since ancient times. The Romans were renowned for its use, as at the Limyra Bridge in Turkey. Until the turn of the 20th century almost all falsework was constructed from timber. To compensate for timber shortages in different regions and to ra ...

Romanesque Architecture
Romanesque architecture is an architectural style of medieval Europe characterized by semi-circular arches. There is no consensus for the beginning date of the Romanesque style, with proposals ranging from the 6th to the 11th century, this later date being the most commonly held. In the 12th century it developed into the Gothic style, marked by pointed arches. Examples of Romanesque architecture can be found across the continent, making it the first pan-European architectural style since Imperial Roman architecture. The Romanesque style in England and Sicily is traditionally referred to as Norman architecture. Combining features of ancient Roman and Byzantine buildings and other local traditions, Romanesque architecture is known by its massive quality, thick walls, round arches, sturdy pillars, barrel vaults, large towers and decorative arcading. Each building has clearly defined forms, frequently of very regular, symmetrical plan; the overall appearance is one of simplic ...

Ablaq
Ablaq ( ar, أبلق; particolored; literally 'piebald') is an architectural technique involving alternating or fluctuating rows of light and dark stone. Records trace the beginnings of this type of masonry technique to the southern parts of Syria. It is associated as an Arabic term, especially as related to Arabic Islamic architectural decoration. The first recorded use of the term ''ablaq'' pertained to repairs of the Great Mosque of Damascus in 1109, but the technique itself was used much earlier. Technique This technique is a feature of Islamic architecture. The ablaq decorative technique is thought to maybe be a derivative from the ancient Byzantine Empire, whose architecture used alternate sequential runs of light colored ashlar stone and darker colored orange brick. The first known use of the term ablaq in building techniques is in masonry work in reconstruction improvements to the walls of the Umayyad Mosque of Damascus. According to records, these reconstruction m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moorish Architecture
Moorish architecture is a style within Islamic architecture which developed in the western Islamic world, including al-Andalus (on the Iberian peninsula) and what is now Morocco, Algeria, and Tunisia (part of the Maghreb). The term "Moorish" comes from the historical Western European designation of the Muslim inhabitants of these regions as "Moors". Scholarly references on Islamic architecture often refer to this architectural tradition by a more geographic designation, such as architecture of the Islamic West or architecture of the Western Islamic lands, and some references on Islamic art and architecture consider use of the term "Moorish" to be outdated or contested. This architectural style blended influences from Berber culture in North Africa, pre-Islamic Iberia (Roman, Byzantine, and Visigothic), and contemporary artistic currents in the Islamic Middle East to elaborate a unique style over centuries with recognizable features such as the horseshoe arch, '' riad'' gardens ( ...
