Tension Fabric Buildings
Tension fabric buildings are constructed using a rigid frame—which can consist of timber, steel, rigid plastic, or aluminum—and a sturdy fabric outer membrane. Once the frame is erected, the fabric cover is stretched over the frame. The fabric cover is tensioned to provide the stable structural support of the building. The fabric is tensioned using multiple methods, varying by manufacturer, to create a tight fitting cover membrane. Compared to traditional or conventional buildings, tension fabric buildings may have lower operational costs due to the daylight that comes through the fabric roof when light-coloured fabrics are used. This natural lighting process is known as daylighting and can improve both energy use and life-cycle costs, as well as occupant health. Tension fabric structures may be more quickly installed than traditional structures as they use fewer materials and therefore usually require less ground works to install. Some tension fabric structures, partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Government
A government is the system or group of people governing an organized community, generally a state. In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. In many countries, the government has a kind of constitution, a statement of its governing principles and philosophy. While all types of organizations have governance, the term ''government'' is often used more specifically to refer to the approximately 200 independent national governments and subsidiary organizations. The major types of political systems in the modern era are democracies, monarchies, and authoritarian and totalitarian regimes. Historically prevalent forms of government include monarchy, aristocracy, timocracy, oligarchy, democracy, theocracy, and tyranny. These forms are not always mutually exclusive, and mixed govern ...

Building Code
A building code (also building control or building regulations) is a set of rules that specify the standards for constructed objects such as buildings and non-building structures. Buildings must conform to the code to obtain planning permission, usually from a local council. The main purpose of building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building codes are generally intended to be applied by architects, engineers, interior designers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants, and others. Codes regulate the design and construction of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging ( plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'': low-density polyethylene is extruded using high pressure () and high temperature (), while high-density polyethylene is extruded using low pressure () and low temperature (). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. History Polyethylene was first synthesized by the German chemist Hans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Crane
An overhead crane, commonly called a bridge crane, is a type of crane found in industrial environments. An overhead crane consists of two parallel rails seated on longitudinal I-beams attached to opposite steel columns by means of brackets. The traveling bridge spans the gap. A hoist, the lifting component of a crane, travels along the bridge. If the bridge is rigidly supported on two or more legs running on two fixed rails at ground level, the crane is called a gantry crane (USA, ASME B30 series) or a ''goliath crane'' (UK, BS 466). Unlike mobile or construction cranes, overhead cranes are typically used for either manufacturing or maintenance applications, where efficiency or downtime are critical factors. History In 1876 Sampson Moore in England designed and supplied the first ever electric overhead crane, which was used to hoist guns at the Royal Arsenal in Woolwich, London. Since that time Alliance Machine, now defunct, holds an AISE citation for one of the earliest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pre-engineered Building
In structural engineering, a pre-engineered building (PEB) is designed by a PEB supplier or PEB manufacturer with a single design to be fabricated using various materials and methods to satisfy a wide range of structural and aesthetic design requirements. This is contrasted with a building built to a design that was created specifically for that building. Within some geographic industry sectors pre-engineered buildings are also called pre-engineered metal buildings (PEMB) or, as is becoming increasingly common due to the reduced amount of pre-engineering involved in custom computer-aided designs, simply engineered metal buildings (EMB). During the 1960s, standardized engineering designs for buildings were first marketed as PEBs. Historically, the primary framing structure of a pre-engineered building is an assembly of -shaped members, often referred to as I-beams. In pre-engineered buildings, the I beams used are usually formed by welding together steel plates to form the I secti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association Football
Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players who primarily use their feet to propel the ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposition by moving the ball beyond the goal line into a rectangular framed goal defended by the opposing side. Traditionally, the game has been played over two 45 minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries, it is considered the world's most popular sport. The game of association football is played in accordance with the Laws of the Game, a set of rules that has been in effect since 1863 with the International Football Association Board (IFAB) maintaining them since 1886. The game is played with a football that is in circumference. The two teams compete to get the ball into the other team's goal (between the posts and under t ...

Rugby Football
Rugby football is the collective name for the team sports of rugby union and rugby league. Canadian football and, to a lesser extent, American football were once considered forms of rugby football, but are seldom now referred to as such. The governing body of Canadian football, Football Canada, was known as the Canadian Rugby Union as late as 1967, more than fifty years after the sport parted ways with rugby rules. Rugby football started about 1845 at Rugby School in Rugby, Warwickshire, England, although forms of football in which the ball was carried and tossed date to the Middle Ages (see medieval football). Rugby football spread to other Public school (United Kingdom), English public schools in the 19th century and across the British Empire as former pupils continued to play it. Rugby football split into two codes in 1895, when twenty-one clubs from the North of England left the Rugby Football Union to form the Rugby Football League, Northern Rugby Football Union (renamed ...

Gaelic Games
Gaelic games ( ga, Cluichí Gaelacha) are a set of sports played worldwide, though they are particularly popular in Ireland, where they originated. They include Gaelic football, hurling, Gaelic handball and rounders. Football and hurling, the most popular of the sports, are both organised by the Gaelic Athletic Association (GAA). Women's versions of hurling and football are also played: camogie, organised by the Camogie Association of Ireland, and ladies' Gaelic football, organised by the Ladies' Gaelic Football Association. While women's versions are not organised by the GAA (with the exception of handball, where men's and women's handball competitions are both organised by the GAA Handball organisation), they are closely associated with it but are still separate organisations. Gaelic games clubs exist all over the world. They are Ireland's most popular sports, ahead of rugby union and association football. Almost a million people (977,723) attended 45 GAA senior championshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sport Ireland
Sport Ireland ( ga, Spórt Éireann), formerly the Irish Sports Council, is a statutory authority that oversees, and partly funds, the development of sport within Ireland. It is located at the National Sports Campus in the townland of Sheephill near Abbotstown House in Dublin. Sport Ireland was established in July 1999 under powers provided by the Irish Sports Council Act.

Column
A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. The term ''column'' applies especially to a large round support (the shaft of the column) with a capital and a base or pedestal, which is made of stone, or appearing to be so. A small wooden or metal support is typically called a ''post''. Supports with a rectangular or other non-round section are usually called ''piers''. For the purpose of wind or earthquake engineering, columns may be designed to resist lateral forces. Other compression members are often termed "columns" because of the similar stress conditions. Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest. In architecture, "column" refers to such a structural element that also has certain proportional and decorative featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainout (sports)
Rainout, washout, rain delay, and rain stopped play are terms regarding an outdoor event, generally a sporting event, delayed or canceled due to rain, or the threat of rain. It is not to be confused with a type of out in baseball, though a baseball game can be rained out. Delays due to other forms of weather are named "snow delay", "lightning delay", "thunderstorm delay", or "fog delay" (or generically "weather delay"), while there are many other effects of weather on sport. Also, a night game can be delayed if the floodlight system fails. Often spectators will be issued a ticket for a make up event, known as a " rain check". Sports typically stopped due to the onset of rain include baseball, golf, tennis, and cricket, where even slightly damp conditions in the latter three sports seriously affect playing quality and the players' safety. In the case of tennis, several venues (such as those of Wimbledon and the Australian Open) have built retractable roofs atop their existing courts ...
