Iron Frame
The term iron frame describes the structural use of either cast iron or wrought iron in the columns and Beam (structure), beams of a building. While popular in the 19th century, the iron frame was displaced by the steel frame in the early 20th century. Cast iron Columns made of cast iron were introduced in the 1770s, the first building with multiple storeys using cast iron for both columns and beams is the Ditherington Flax Mill in Shrewsbury (1797). Columns were joined usually at the floor level and sometimes bolted together, the longer beams were made of sections that were also kept together by bolts. At first, the stiffness of the frame was achieved through the use of masonry that filled the openings in the frame, but since 1844, a ''rigid frame'' was used that was stable by itself (former fire station at the Portsmouth Dockyard). With its high compression strength, the cast iron is well-suited for columns. At first, the cruciform profile was used, later displaced by the hol ...

Cast Iron
Cast iron is a class of iron– carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applicatio ...

Girder
A girder () is a support beam used in construction. It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing ''flanges'' separated by a stabilizing ''web'', but may also have a box shape, Z shape, or other forms. Girders are commonly used to build bridges. A girt is a vertically aligned girder placed to resist shear loads. Small steel girders are rolled into shape. Larger girders (1 m/3 feet deep or more) are made as plate girders, welded or bolted together from separate pieces of steel plate. The Warren type girder replaces the solid web with an open latticework truss between the flanges. This arrangement combines strength with economy of materials, minimizing weight and thereby reducing loads and expense. Patented in 1848 by its designers James Warren and Willoughby Theobald Monzani, its structure consists of longitudinal members joined only by angled cross-members ...

Sheet Metal
Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Sheet metal is one of the fundamental forms used in metalworking, and it can be cut and bent into a variety of shapes. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous ( iron-based) metals and nonferrous metals such as aluminum or copper. Co ...

Shed Number 78, Sheerness Dockyard
Shed Number 78, Sheerness Dockyard (also known as Boat Store Number 78 or simply Sheerness Boat Store) is a disused industrial building at Sheerness Dockyard, on the Isle of Sheppey in north Kent. The building was constructed at the Royal Navy Dockyard in Sheerness in 1856–60, as a store for small boats and a warehouse. It became a listed building in 1962, upgraded to Grade I in 1999, but it has been on the Heritage at Risk Register for many years. History The building was constructed for the Admiralty Works Department by Colonel Godfrey Thomas Green CB of the Royal Engineers (1807-1886) (formerly from the Bengal Sappers and Miners, and later Director of Admiralty Works), and William Scamp (1801-1872), with ironwork cast by Henry Grissell's Regent's Canal Ironworks. The design was based on slip covers at naval dockyards built during the 1830s and 1840s, for example the Grade I listed covered slips at Chatham Dockyard, but, unlike those buildings, it relies on the rigidi ...

The Crystal Palace
The Crystal Palace was a cast iron and plate glass structure, originally built in Hyde Park, London, to house the Great Exhibition of 1851. The exhibition took place from 1 May to 15 October 1851, and more than 14,000 exhibitors from around the world gathered in its exhibition space to display examples of technology developed in the Industrial Revolution. Designed by Joseph Paxton, the Great Exhibition building was long, with an interior height of , and was three times the size of St Paul's Cathedral. The introduction of the sheet glass method into Britain by Chance Brothers in 1832 made possible the production of large sheets of cheap but strong glass, and its use in the Crystal Palace created a structure with the greatest area of glass ever seen in a building. It astonished visitors with its clear walls and ceilings that did not require interior lights. It has been suggested that the name of the building resulted from a piece penned by the playwright Douglas Jerrold, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I-beam
An I-beam, also known as H-beam (for universal column, UC), w-beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double-T (especially in Polish, Bulgarian, Spanish, Italian and German), is a beam with an or -shaped cross-section. The horizontal elements of the are flanges, and the vertical element is the "web". I-beams are usually made of structural steel and are used in construction and civil engineering. The web resists shear forces, while the flanges resist most of the bending moment experienced by the beam. The Euler–Bernoulli beam equation shows that the I-shaped section is a very efficient form for carrying both bending and shear loads in the plane of the web. On the other hand, the cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred. History The method of producing an I-beam, as rolled from a single piece of wrought iron, wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Classical Antiquity
Classical antiquity (also the classical era, classical period or classical age) is the period of cultural history between the 8th century BC and the 5th century AD centred on the Mediterranean Sea, comprising the interlocking civilizations of ancient Greece and ancient Rome known as the Greco-Roman world. It is the period in which both Greek and Roman societies flourished and wielded huge influence throughout much of Europe, North Africa, and Western Asia. Conventionally, it is taken to begin with the earliest-recorded Epic Greek poetry of Homer (8th–7th-century BC), and continues through the emergence of Christianity (1st century AD) and the fall of the Western Roman Empire (5th-century AD). It ends with the decline of classical culture during late antiquity (250–750), a period overlapping with the Early Middle Ages (600–1000). Such a wide span of history and territory covers many disparate cultures and periods. ''Classical antiquity'' may also refer to an ...

Cramp (construction)
A cramp is a sudden, involuntary, painful skeletal muscle contraction or overshortening associated with electrical activity; while generally temporary and non-damaging, they can cause significant pain and a paralysis-like immobility of the affected muscle. A cramp usually goes away on its own over a period of several seconds, or minutes. Cramps are common and tend to occur at rest, usually at night (nocturnal leg cramps). They are also often associated with pregnancy, physical exercise or overexertion, age (common in older adults), in such cases, cramps are called idiopathic, because there is no underlying pathology. In addition to those benign conditions cramps are also associated with many pathologic conditions. Skeletal muscle cramps may be caused by muscle fatigue or a lack of electrolytes such as sodium (a condition called hyponatremia), potassium (called hypokalemia), or magnesium (called hypomagnesemia). Some skeletal muscle cramps do not have a known cause. Motor neuro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
