Cantilevers
A cantilever is a rigid structural element that extends horizontally and is supported at only 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 southe ...

Fallingwater
Fallingwater is a house designed by the architect Frank Lloyd Wright in 1935 in the Laurel Highlands of southwest Pennsylvania, about southeast of Pittsburgh in the United States. It is built partly over a waterfall on Bear Run in the Mill Run section of Stewart Township, Fayette County, Pennsylvania. The house was designed to serve as a weekend retreat for Liliane and Edgar J. Kaufmann, the owner of Pittsburgh's Kaufmann's Department Store. After its completion, ''Time'' called Fallingwater Wright's "most beautiful job" and it is listed among '' Smithsonian''s "Life List of 28 Places to See Before You Die". The house was designated a National Historic Landmark on May 11th, 1976. In 1991, members of the American Institute of Architects named Fallingwater the "best all-time work of American architecture" and in 2007, it was ranked 29th on the list of America's Favorite Architecture according to the AIA. The house and seven other Wright constructions were inscribed as a Worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forth Rail Bridge
The Forth Bridge is a cantilever railway bridge across the Firth of Forth in the east of Scotland, west of central Edinburgh. Completed in 1890, it is considered a symbol of Scotland (having been voted Scotland's greatest man-made wonder in 2016), and is a UNESCO World Heritage Site. It was designed by English engineers Sir John Fowler and Sir Benjamin Baker. It is sometimes referred to as the Forth Rail Bridge (to distinguish it from the adjacent Forth Road Bridge), although this has never been its official name. Construction of the bridge began in 1882 and it was opened on 4 March 1890 by the Duke of Rothesay, the future Edward VII. The bridge carries the Edinburgh–Aberdeen line across the Forth between the villages of South Queensferry and North Queensferry and has a total length of . When it opened it had the longest single cantilever bridge span in the world, until 1919 when the Quebec Bridge in Canada was completed. It continues to be the world's second-longest si ...

Cantilever Bridge
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers). For small footbridges, the cantilevers may be simple beam (structure), beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over , and can be more easily constructed at difficult crossings by virtue of using little or no falsework. Origins Civil engineer, Engineers in the 19th century understood that a bridge that was continuous across multiple supports would distribute the loads among them. This would result in lower stresses in the girder or truss and meant that longer spans could be built. Several 19th-century engineers patented continuous bridges with hinge points mid-span. The use of a hing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truss Arch Bridge
A truss arch bridge combines the elements of the truss bridge and the arch bridge. The actual resolution of forces will depend upon the design. If no horizontal thrusting forces are generated this becomes an arch-shaped truss, essentially a bent beam – see moon bridge for an example. If horizontal thrust is generated but the apex of the arch is a pin joint, this is termed a three-hinged arch. If no hinge exists at the apex, it will normally be a two-hinged arch. In the ''Iron Bridge'' shown below, the structure of each frame emulates the kind of structure that previously had been made of wood. Such a wood structure uses closely fitted beams pinned together, so the members within the frames are not free to move relative to one another, as they are in a pin-jointed truss structure that allows rotation at the pin joint. Such rigid structures (which impose bending stresses upon the elements) were further developed in the 20th century as the Vierendeel truss. Image:Garabit.jpg, G ...

Old Trafford (football Ground)
Old Trafford () is a football stadium in Old Trafford, Greater Manchester, England, and the home of Manchester United. With a capacity of 74,310 it is the largest club football stadium (and second-largest football stadium overall after Wembley Stadium) in the United Kingdom, and the eleventh-largest in Europe. It is about from Old Trafford Cricket Ground and the adjacent tram stop. Nicknamed "The Theatre of Dreams" by Bobby Charlton, Old Trafford has been United's home ground since 1910, although from 1941 to 1949 the club shared Maine Road with local rivals Manchester City as a result of Second World War bomb damage. Old Trafford underwent several expansions in the 1990s and 2000s, including the addition of extra tiers to the North, West and East Stands, almost returning the stadium to its original capacity of 80,000. Future expansion is likely to involve the addition of a second tier to the South Stand, which would raise the capacity to around 88,000. The stadium's reco ...

Timber Framing
Timber framing (german: Holzfachwerk) and "post-and-beam" construction are traditional methods of building with heavy timbers, creating structures using squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs. If the structural frame of 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 dimensional lumber. Hewing this with broadaxes, adzes, and draw knives and using hand-powered braces and augers (brace and bit) and other woodworking tools, artisans or framers could gradually assemble a building. Since this building method has been used for thousands of years in many parts of the world, many st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Navajo Bridge
Navajo Bridge is the name of twin steel spandrel arch bridges that cross the Colorado River in the Grand Canyon National Park (near Lees Ferry) in northern Coconino County, Arizona, United States. The newer of the two spans carries vehicular traffic on U.S. Route 89A (US 89A) over Marble Canyon between Bitter Springs and Jacob Lake, allowing travel into a remote Arizona Strip region north of the Colorado River including the North Rim of Grand Canyon National Park. Prior to completion of the first Navajo Bridge, one of the only Colorado River crossings between Arizona and Utah was located about upstream from the bridge site, at the mouth of Glen Canyon where Lees Ferry service had operated since 1873. The ferry site had been chosen as the only relatively easy access to the river for both northbound and southbound travelers. By the 1920s, automobile traffic began using the ferry, though it was not considered a safe and reliable crossing due to adverse weather and fl ...

Miami Stadium
Miami Stadium (later officially known as Bobby Maduro Miami Stadium) was a baseball stadium in Miami, Florida. It was primarily used for baseball, and was the home field of the Miami Marlins minor league baseball team, as well as other minor league teams. It opened in 1949 and held 13,500 people. left, View of the stadium in 1950s The stadium was located on the block bounded by Northwest 23rd Street (south – first base), Northwest 10th Avenue (west – third base), and Northwest 8th Avenue (east – right field), with an open area behind left field extending about a block north. A distinguishing feature of the ballpark was a high arched cantilever-type roof over the grandstand, in contrast to the typical styles of either flat and slightly sloping, or peaked like a house. This design enabled the ballpark to have a roof that covered most of the spectator area without any posts blocking the spectators' view. Al López Field in Tampa employed a somewhat similar design with a les ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (structure)
A beam is a structural element that primarily resists loads applied laterally to the beam's axis (an element designed to carry primarily axial load would be a strut or column). Its mode of deflection is primarily by bending. The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all the forces acting on the beam is to produce shear forces and bending moments within the beams, that in turn induce internal stresses, strains and deflections of the beam. Beams are characterized by their manner of support, profile (shape of cross-section), equilibrium conditions, length, and their material. Beams are traditionally descriptions of building or civil engineering structural elements, where the beams are horizontal and carry vertical loads. However, any structure may contain beams, for instance automobile frames, aircraft components, machine frames, and other mechanical or structural systems. In these structures, any structural eleme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
