Jettied
Jettying (jetty, jutty, from Old French ''getee, jette'') is a building technique used in medieval timber framing, timber-frame buildings in which an upper floor projects beyond the dimensions of the floor below. This has the advantage of increasing the available space in the building without obstructing the street. Jettied floors are also termed ''jetties''. In the U.S., the most common surviving colonial version of this is the garrison house. Most jetties are external, but some early medieval houses were built with internal jetties. Structure A jetty is an upper floor that depends on a cantilever system in which a horizontal beam, the jetty bressummer, supports the wall above and projects forward beyond the floor below (a technique also called ''oversailing''). The bressummer (or breastsummer) itself rests on the ends of a row of jetty beams or joists which are supported by jetty plates. Jetty joists in their turn were slotted sideways into the diagonal dragon beams at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timber Framing
Timber framing () and "post-and-beam" construction are traditional methods of building with heavy Beam (structure), timbers, creating structures using squared-off and carefully fitted and Woodworking joints, joined timbers with joints secured by large wooden pegs. If the Structural system, structural frame of Load-bearing wall, load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered, and in many cases the infill between timbers will be used for decorative effect. The country most known for this kind of architecture is Germany, where timber-framed houses are spread all over the country. The method comes from working directly from logs and trees rather than pre-cut Lumber#Dimensional lumber, dimensional lumber. Artisans or framers would gradually assemble a building by hewing logs or trees with broadaxes, adzes, and draw knife, draw knives and by using woodworking tools, such as hand-powered Brace (tool), braces and Auger (dril ...

Cantilever
A cantilever is a rigid structural element that extends horizontally and is unsupported at one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the sou ...

Pennsylvania Barn
A Pennsylvania barn is a type of bank barn built in the United States from about 1790 to 1900. The style's most distinguishing feature is an overshoot or forebay, an area where one or more walls overshoot its foundation. These barns were banked and set into a hillside to ensure easy access to the basement and the level above. Almost all Pennsylvania barns also have gable roofs. Barn scholar Robert Ensminger classified the Pennsylvania barn into three types: Standard Pennsylvania, Sweitzer, and Extended Pennsylvania barns.Ensminger, Robert F. ''The Pennsylvania barn: its origin, evolution, and distribution in North America''. 2nd ed. Baltimore: Johns Hopkins University Press, 2003. The Pennsylvania-style barns were also built in the Shenandoah Valley, as well as west of Pennsylvania and in Canada. Standard Pennsylvania barn "The Standard Pennsylvania barn is the most numerous and widely distributed class of the Pennsylvania barns." These were built between 1790 and 1890. The key c ...

Corbel
In architecture, a corbel is a structural piece of stone, wood or metal keyed into and projecting from a wall to carry a wikt:superincumbent, bearing weight, a type of bracket (architecture), bracket. A corbel is a solid piece of material in the wall, whereas a console is a piece applied to the structure. A piece of timber projecting in the same way was called a "tassel" or a "bragger" in England. The technique of corbelling, where rows of corbels deeply keyed inside a wall support a projecting wall or parapet, has been used since Neolithic (New Stone Age) times. It is common in medieval architecture and in the Scottish baronial style as well as in the vocabulary of classical architecture, such as the modillions of a Corinthian order, Corinthian cornice. The corbel arch and corbel vault use the technique systematically to make openings in walls and to form ceilings. These are found in the early architecture of most cultures, from Eurasia to Pre-Columbian architecture. A conso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhang (architecture)
In architecture, an overhang is a protruding structure that may provide protection for lower levels. Overhangs on two sides of Pennsylvania Dutch barns protect doors, windows, and other lower-level structures. Overhangs on all four sides of barns and larger, older farmhouses are common in Swiss architecture. An overhanging eave is the edge of a roof, protruding outwards from the side of the building, generally to provide weather protection. History Overhangs are also common in medieval Indian architecture—especially Mughal architecture of the 16th–18th century, where they are called '' chhajja'', often supported by ornate corbels and also seen in Hindu temple architecture. Later, these were adopted by Indo-Saracenic architecture, which flourished during the British Raj. Extensive overhangs were incorporated in early Buddhist architecture; were seen in early Buddhist temples; and later became part of Tibetan architecture, Chinese architecture, and eventually, traditional Ja ...

Machicolation
In architecture, a machicolation () is an opening between the supporting corbels of a battlement through which defenders could target attackers who had reached the base of the defensive wall. A smaller related structure that only protects key points of a fortification are referred to as Bretèche. Machicolation, hoarding, bretèche, and murder holes are all similar defensive features serving the same purpose, that is to enable defenders atop a defensive structure to target attackers below. The primary benefit of the design allowed defenders to remain behind cover rather than being exposed when leaning over the parapet. They were common in defensive fortifications until the widespread adoption of gunpowder weapons made them obsolete. Etymology The word machicolation derives from Old French , mentioned in Medieval Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... , mentioned in Medieval Lat ...

945 Madison Avenue
945 Madison Avenue, also known as the Breuer Building, is a museum building on the Upper East Side of Manhattan, New York City. Built from 1964 to 1966 as the third home of the Whitney Museum of American Art, it subsequently held a branch of the Metropolitan Museum of Art and the Frick Collection before becoming the headquarters of Sotheby's auction house. Marcel Breuer and Hamilton P. Smith were the primary architects, with Michael H. Irving as the consulting architect and Paul Weidlinger as the structural engineer. 945 Madison Avenue was Breuer's most significant design in New York City and one of the most important of his career. It was also his first museum commission, and his first and only remaining work in Manhattan. The building sits on a site at Madison Avenue and 75th Street that was once occupied by six 1880s rowhouses. The building is usually described as part of the Modernist art and architecture movement, and is often described as part of the narrower Brutalis ...

Herculaneum
Herculaneum is an ancient Rome, ancient Roman town located in the modern-day ''comune'' of Ercolano, Campania, Italy. Herculaneum was buried under a massive pyroclastic flow in the eruption of Mount Vesuvius in 79 AD. Like the nearby city of Pompeii, Herculaneum is famous as one of the few ancient cities to be preserved nearly intact, as the solidified material from the volcano that blanketed the town protected it against looting and the elements. Although less known than Pompeii today, it was the first and, for a long time, the only discovered Vesuvian city (in 1709). Pompeii was revealed in 1748 and identified in 1763. Unlike Pompeii, the mainly Pyroclastic rock, pyroclastic material that covered Herculaneum carbonization, carbonized and preserved more wooden objects such as roofs, beds, and doors, as well as other organic-based materials such as Herculaneum loaf, food and papyrus. According to the traditional tale, the city was rediscovered by chance in 1709 during the dri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opus Craticum
''Opus craticum'' or ''craticii'' is an ancient Roman construction technique described by Vitruvius in his books ''De architectura'' as wattlework which is plastered over. It is often employed to construct partition walls and floors. Vitruvius disparaged this building technique as a grave fire risk, likely to have cracked plaster, and not durable. Surviving examples were found in the archaeological excavations at Pompeii and more so at Herculaneum, buried by the eruption of Mount Vesuvius in 79 AD and excavated beginning in 1929. Scholarly confusion exists since the term ''opus craticium'' is also used for the Roman building technique very similar, but not identified as being directly related to half-timbering, a timber framework with the wall infill of stones in mortar called ''opus incertum''. An example of this technique is the House of Opus Craticum in Herculaneum. This building, which was constructed some time in the first century or earlier, was reconstructed at Herculaneum ...
