Lockyer Creek Railway Bridge (Lockyer)
Lockyer Creek Railway Bridge (Lockyer) is a heritage-listed railway bridge on the Toowoomba - Helidon railway line over Lockyer Creek at Lockyer, Lockyer Valley Region, Queensland, Australia. It was designed by William Pagan and built from 1909 to 1910. It was added to the Queensland Heritage Register on 21 October 1992. History This bridge was built in 1910 as part of the Brisbane–Toowoomba railway and was one of three railway bridges constructed over Lockyer Creek. The railway opened for traffic between Helidon and Toowoomba on 1 May 1867. From the 1870s there has been a continuing process of improving the Main Line between Brisbane and Toowoomba because of its importance as a major arterial route. As part of that process, which required the replacement of original bridges to carry heavier loads, construction work began in 1908 on a new bridge and deviation over the Lockyer Creek tributary at . The design for the innovative reinforced concrete arch bridge was comple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Line Railway, Queensland
The Main Line is a railway line in South East Queensland, Australia. It was opened in a series of sections between 1865 and 1867. It commences at Roma St Station in Brisbane and extends west 161 km to Toowoomba. It is the first narrow gauge main line constructed in the world. The section of the line from the end of Murphys Creek railway station to the Ruthven Street overbridge, Harlaxton is listed on the Queensland Heritage Register. The Murphys Creek Railway Complex, the Lockyer Creek Railway Bridge (Lockyer), the Lockyer Creek Railway Bridge (Murphys Creek) and Swansons Rail Bridge are also heritage listed. History The section from Ipswich (a city about from Brisbane) to Grandchester (originally Bigge's Camp) was the first section of railway line opened in Queensland, on 31 July 1865. Queensland Railways (QR) was the first operator in the world to adopt narrow gauge (in this case ) for a main line, and this remains the system wide gauge within Queensland tod ...

Railway Bridges In Queensland
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in Track (rail transport), tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on Railroad tie, sleepers (ties) set in track ballast, ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lockyer Creek Railway Bridge (Clarendon)
Lockyer Creek Railway Bridge is a heritage-listed railway bridge on the Brisbane Valley railway line over Lockyer Creek at Clarendon, Somerset Region, Queensland, Australia. It was designed by Henry Charles Stanley and built from 1885 to 1886 by H A Brigg. It was added to the Queensland Heritage Register on 21 October 1992. History The second section of the Brisbane Valley Branch line from Lowood to Esk was let on contract to H. A. Brigg on 2 December 1884 for . The line was opened for traffic between Lowood and Esk on 9 August 1886. Operating the Brisbane Valley Branch was expensive because the light standard of the line limited engines to B15 standard. As there were many heavy grades on the line, more powerful locomotives could produce substantial savings in the number of trains needed. Using Great Depression relief labour to reduce the cost, strengthening the line to C16 and C17 standard was completed between 1931 and 1933. In 1932 a central timber pier was added ...

Parabolic Arch
A parabolic arch is an arch in the shape of a parabola.Article about parabolic arch by The Free DictionaryParabolic arch , Article about parabolic arch by The Free Dictionary accessdate: March 2, 2017 In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms. Description The mathematics While a parabolic arch may resemble a catenary arch, a parabola is a quadratic function while a catenary is the hyperbolic cosine, , a sum of two exponential functions. One parabola is , and hyperbolic cosine is . The curves are unrelated. The line of thrust Unlike a catenary arch, the parabolic arch employs the principle that when weight is uniformly applied above, the internal compression (see line of thrust) resulting from that weight will follow a parabolic curve. Of all arch types, the parabolic arch produces the most thrust at the base. Also, it can span the widest area. It is commonly used in bridge design, ...

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] |
Spandrel
A spandrel is a roughly triangular space, usually found in pairs, between the top of an arch and a rectangular frame; between the tops of two adjacent arches or one of the four spaces between a circle within a square. They are frequently filled with decorative elements. Meaning There are four or five accepted and cognate meanings of the term ''spandrel'' in architectural and art history, mostly relating to the space between a curved figure and a rectangular boundary – such as the space between the curve of an arch and a rectilinear bounding moulding, or the wallspace bounded by adjacent arches in an arcade and the stringcourse or moulding above them, or the space between the central medallion of a carpet and its rectangular corners, or the space between the circular face of a clock and the corners of the square revealed by its hood. Also included is the space under a flight of stairs, if it is not occupied by another flight of stairs. In a building with more than one floor ...

Span (architecture)
Span is the distance between two intermediate supports for a structure, e.g. a beam (structure), beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of Antenna (radio), antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and Deflection (engineering), deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the tensile stress, stress) will quadruple, and ...
