Bridgebuilding - Facts and Figures
Bridgebuilding is often associated with forward progress and exploration
and since ancient times, the effective construction and destruction of bridges has been one of the primary responsibilities of engineers. Bridges provide smooth and safe crossing where it would otherwise be extremely difficult and hazardous, if not impossible.
It can be easy to take things for granted, and bridges are no exception. But bridgebuilding is by no means an easy task. Back before the days of steel and reinforced concrete, people used to build bridges out of wood or stone. But I'm sure you can imagine the limits these materials place on the engineer. This is why longer bridges were limited to the arch types.
Well, let's talk about what kind of options are available. Obviously, the simplest way would be to build what is called a beam bridge. This can be as basic as laying logs across a small stream. But beam bridges can only get so long before they begin needing support in some form. Columns were the earliest forms of support, but columns are not always feasible.
Even with the superior qualities of today's steel, beam bridges rarely span more than 250 feet. Arch bridges on the other hand can span over 1800 feet provided steel and/or reinforced concrete are used. But even arch bridges made of just stone are known to span up to 480 feet!
Since the development of steel, other bridge types have come into play. Namely, steel truss and suspension. Truss bridges incorporate a system of triangular bracing spreading the load evenly throughout. These truss systems can be above or below the bridge deck - or both - and can also arch up or down toward the deck at given intervals to cut cost and weight. The longest truss bridge at present is the Ikitsuki bridge, spanning 1312 feet, located in Nagasaki, Japan.
Suspension bridges are perhaps the newest and most majestic-looking of the lot, and understandably so! Suspension bridges can span the greatest lengths - up to 7,000 feet - making them the bridge of choice for projects requiring substantial length. Suspension bridges also utilize truss systems below the deck to supplement the load-bearing capacity as well as to counter torsion.

Truss Bridge $97.19 High Quality Content by WIKIPEDIA articles A truss bridge is a bridge composed of connected elements (typically straight) which may be stressed from tension, compression, or sometimes both in response to dynamic loads. Truss bridges are one of the oldest types of modern bridges. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by nineteenth and early twentieth century engineers. A truss bridge is economical to construct owing to its efficient use of materials. The nature of a truss allows for the analysis of the structure using a few assumptions and the application of Newtons laws of motion according to branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet. This assumption means that members of the truss (chords, verticals and diagonals) will act only in tension or compression. A more complex analysis is required where rigid joints impose significant bending loads upon the elements, as in a Vierendeel truss.

Walnut Street Bridge (Tennessee) $68.51 High Quality Content by WIKIPEDIA articles The Walnut Street Bridge is a truss bridge that spans the Tennessee River in Chattanooga, Tennessee.Built in 1890, it was the first to connect Chattanoogas downtown with the North Shore. According to the plaque on the bridge, Edwin Thatcher was the chief engineer for the bridge. The bridges superstructure was assembled by the Smith Bridge Company of Toledo, Ohio, which was a prolific late 19th Century bridge builder. The bridges substructure was constructed by Neeley, Smith and Company of Chattanooga, Tennessee. Most of the parts for the bridge were manufactured by Manly Jail Works of Dalton, Georgia and shipped to the site by rail. The bridges main spans are pinconnected Pennsylvania through truss spans. The top chord of these truss spans are configured in five sections, making the spans similar to the Camelback truss design. The bridge is historically significant as an extremely long and old example of its type. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.
