A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular herelovstory.com connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic herelovstory.com basic types of truss bridges shown in this article have simple designs which could be easily analyzed by. The world's longest suspension bridges are listed according to the length of their main span (i.e. the length of suspended roadway between the bridge's towers). The length of main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

Thanks to the industrial revolution, the tradition of building bridges from stone became a thing of the pastreserved for the English countryside, Lord of the Rings novels and ancient European monuments. Readily available wood and soon thereafter, wrought iron, saw the arrival of truss bridges onto the 19 th century engineering scene.

Inthe first truss bridge design what is the longest truss bridge in the us patented, and the concept quickly took off, with engineers beginning to experiment with different truss styles. Before long there were dozens of different types of truss to excite the keen bridge-builder!

Truss bridges are characterised by their interconnecting triangular structures, which give them the strength to withstand more heavy and dynamic loads than the bridges of old. Nowadays however, there are an abundance of bridge designs available to us.

Suspension, beam, arch and cantilever designs are all able to cope with our modern-day heavy loads of trafficso why choose a truss bridge? The structure of interconnecting triangles means that the load-bearing capacity of truss bridges is huge.

The structure effectively manages both compression and tension, by spreading out the load from the roadway throughout its intricate structure. This means that no one part of the structure is carrying a disproportionate amount of weight. While the truss bridge has many, many linked parts to make up its structureits use of materials is extremely effective.

Materials such as wood, iron and steel are all utilised to their highest potential, and every piece plays a role. The building of a large truss bridge can be a very economical option, when compared to other bridge designs. Where other bridges such as beam and arch bridges may not be a viable option, truss bridges come into their own. They are able to span great lengths, and often used in precarious locations such as deep ravines between mountaintops.

Unlike other bridge designs, the truss bridge is able to carry its roadway on its structure. The load can be carried above deck trussalong the middle through truss or on a bottom truss, which sits below the major truss structure.

The options make the truss bridge both versatile and economical to build. Fun fact: the longest truss bridge in the world is the Ikitsuki Bridge in Japan, which stretches for metres. The structure of a truss bridge is, by design, large. The interconnecting triangular components need to be large in order to bear and distribute heavy loads. This means that in certain restricted spaces, the truss bridge may not be the learning how to speak spanish for kids option.

Economies of scale! The truss bridge uses a LOT of parts. Howeverthe maintenance costs of so many parts can be expensive. A truss bridge, like any load-bearing structure, will require regular and detailed maintenance. So many parts to look after can mean that this is expensivenot to mention time consuming!

Truss bridges are intricate, complex structures. Each and every piece needs to fit how to check for freon leak in car in order to perform its function, and anything less will mean that the bridge simply does not hold a load.

A truss bridge requires detailed engineering and specialist constructionthis does not come cheap. You knowanyone can build a bridge, but it takes an engineer to get you over it. Because truss bridges are so large, and use a lot of materials, they are heavy. Depending on the landscape supporting the bridge, some reinforcement may be necessary to cope with the weight.

The options make the truss bridge both versatile and economical to build. Fun fact: the longest truss bridge in the world is the Ikitsuki Bridge in Japan, which stretches for metres. Disadvantages Requires a lot of space. The structure of a truss bridge is, by design, large. One of the most picturesque state parks in Georgia, Watson Mill Bridge contains the longest covered bridge in the state, spanning feet across the South Fork River. Built in by Washington (W.W.) King, son of freed slave and famous covered-bridge builder Horace King, the bridge is supported by a town lattice truss system held firmly. herelovstory.com is a database of historic or notable bridges in the United States.

The world's longest suspension bridges are listed according to the length of their main span i. The length of main span is the most common method of comparing the sizes of suspension bridges , often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge.

Suspension bridges have the longest spans of any type of bridge. Cable-stayed bridges , the next longest design, are practical for spans up to just over 1 kilometre. Therefore, as of [update] , the 29 longest bridges on this list are the 29 longest spans of all types of vehicular bridges other than floating pontoon bridges. This list includes only completed suspension bridges that carry automobiles or trains. It does not include cable-stayed bridges, footbridges , or pipeline bridges.

Most of the large suspension bridges built in recent years have been in the People's Republic of China. As the following list shows, most of the bridges under construction are also in China.

Prior longest bridges are located in List of longest arch bridge spans. Exceeded by the masonry arch Trezzo sull'Adda Bridge from to , with main span of 72 m. The first suspension bridge to have a concrete deck. The construction methods pioneered in building it would make possible several much larger projects to follow. Sources: [] [] []. From Wikipedia, the free encyclopedia. Wikipedia list article. See also: Timeline of three longest spans. Handbook of International Bridge Engineering.

ISBN Retrieved 3 February via google books. The total length often reflects a project size, while the span length commonly correlates with the engineering complexity involved in designing and constructing of the bridge.

    Whats the point in a having a a video, then telling people to research something. Surely you should be showing people what to do.
