The Forth Bridge1 is a cantileverrailway bridge across the Firth of Forth in the east of Scotland, 9 miles 1. Edinburgh City Centre. It is considered an iconic structure and a symbol of Scotland having been voted Scotlands greatest man made wonder in 2. UNESCOWorld Heritage Site. It was designed by the English engineers Sir John Fowler and Sir Benjamin Baker. It is sometimes referred to as the Forth Rail Bridge to distinguish it from the Forth Road Bridge, though this has never been its official name. Architecture And Construction In Steel By Alan Blanc Pdf FileConstruction of the bridge began in 1. March 1. 89. 0 by the Duke of Rothesay, the future Edward VII. The bridge spans the Forth between the villages of South Queensferry and North Queensferry and has a total length of 8,0. When it opened it had the longest single cantilever bridge span in the world, until 1. Quebec Bridge in Canada was completed. It continues to be the worlds second longest single cantilever span, with a span of 1,7. The bridge and its associated railway infrastructure are owned by Network Rail. BackgroundeditEarlier proposalseditPrior to the construction of the bridge, ferry boats were used to cross the Firth. In 1. James Anderson produced a design for a three span suspension bridge close to the site of the present one. Calling for approximately 2,5. Wilhelm Westhofen said of it and this quantity of iron distributed over the length would have given it a very light and slender appearance, so light indeed that on a dull day it would hardly have been visible, and after a heavy gale probably no longer to be seen on a clear day either. For the railway age, Thomas Bouch designed for the Edinburgh and Northern Railway a roll onroll off ferry between Granton and Burntisland that opened in 1. Tay. 6 In late 1. North British Railway and Edinburgh and Glasgow Railway, which would merge in 1. Stephenson and Toner to design a bridge for the Forth, but the commission was given to Bouch around six months later. It had proven difficult to engineer a suspension bridge that was able to carry railway traffic, and Thomas Bouch, engineer to the North British Railway NBR and Edinburgh and Glasgow Railway, was in 1.

The promoters, however, were concerned about the ability to set foundations in the silty river bottom, as borings had gone as deep as 2. Bouch conducted experiments to demonstrate that it was possible for the silt to support considerable weight. Experiments in late 1. Bouch to continue with the design. In August 1. Richard Hodgson, chairman of the NBR, proposed that the company invest GB1. Bouch proposed using a large pine platform underneath the piers, 8. The platform was launched on 1. June 1. 86. 6 after some difficulty in getting it to move down the greased planks it rested on, and then moored in the harbour for six weeks pending completion. The bridge project was aborted just before the platform was sunk as the NBR expected to lose through traffic following the amalgamation of the Caledonian Railway and the Scottish North Eastern Railway. In September 1. November. By mid 1. NBR was nearly bankrupt, and all work on the Forth and Tay bridges was stopped. Bouchs proposed bridge top along with other proposals on the same principle. The North British Railway took over the ferry at Queensferry in 1. Ratho in 1. 86. 8, establishing a contiguous link with Fife. Interest in bridging the Forth increased again, and Bouch proposed a stiffened steel suspension bridge on roughly the line of the present rail bridge in 1. Inchgarvie. 1. 4After the Tay Bridge collapsed in 1. Bouch dried up and the work stopped. The public inquiry into the disaster, chaired by Henry Cadogan Rothery, found the Tay Bridge to be badly designed, badly constructed and badly maintained, with Bouch being mainly to blame for the defects in construction and maintenance and entirely responsible for the defects in design. After the disaster, which occurred in high winds for which Bouch had not properly accounted, the Board of Trade imposed a lateral wind allowance of 5. Bouchs 1. 87. 1 design had taken a much lower figure of 1. Astronomer Royal, although contemporary analysis showed it would probably have stood, but the engineers making the analysis stated that we do not commit ourselves to an opinion that it is the best possible design. Bouchs design was formally abandoned on 1. January 1. 88. 1, and Sir John Fowler, W. Comunicacion Visual Basic Puerto Serial'>Comunicacion Visual Basic Puerto Serial. H. Barlow and T. E. Harrison, consulting engineers to the project, were invited to give proposals for a bridge. The original and final designs of the Forth Bridge. DimensionseditThe bridge spans the Forth between the villages of South Queensferry and North Queensferry and has a total length of 8,0. The Forth Bridge is 8,0. It consists of two main spans of 1,7. Each main span consists of two 6. The weight of the bridge superstructure was 5. The bridge also used 6. The three great four tower cantilever structures are 3. These were constructed using 7. Inchgarvie acted as cofferdams, while the remaining two on Inchgarvie and those for the south cantilever, where the river bed was 9. Engineering principlesedit. Illustration of the cantilever principle. The bridge is built on the principle of the cantilever bridge, where a cantilever beam supports a light central girder, a principle that has been used for thousands of years in the construction of bridges. In order to illustrate the use of tension and compression in the bridge, a demonstration in 1. Japanese engineer Kaichi Watanabe supported between Fowler and Baker sitting in chairs. Fowler and Baker represent the cantilevers, with their arms in tension and the sticks under compression, and the bricks the cantilever end piers which are weighted with cast iron. MaterialseditThe bridge was the first major structure in Britain to be constructed of steel 2. French contemporary, the Eiffel Tower, was built of wrought iron. Large amounts of steel became available after the invention of the Bessemer process, patented in 1. In 1. 85. 9, the Board of Trade imposed a limit of 7. Nmm. 2 1. 1,2. 48 psi for the maximum design stress in railway bridges this was revised as technology progressed. The original design required 4. Siemens steel works in Landore, Wales and the remainder from the Steel Company of Scotlands works near Glasgow. When modifications to the design necessitated a further 1.

Around three or four thousand tons of steel was scrapped, some of which was used for temporary purposes, resulting in the discrepancy between the quantity delivered and the quantity erected. ApproacheseditAfter Dalmeny railway station, the track curves very slightly to the east before coming to the southern approach viaduct. After the railway crosses the bridge, it passes through North Queensferry railway station, before curving to the west, and then back to the east over the Jamestown Viaduct. The approaches were built under separate contract and were to the design of the engineer James Carswell. The supports of the approach viaducts are tapered to prevent the impression of the columns widening as they approach the top, and an evaluation of the aesthetics of the Bridge in 2.
