Transcript of The Truss Bridge

THE TRUSS BRIDGE By: Desiree Francis The "Truss Bridge" is similar to the beam bridge except much stronger. These bridges use a pattern of geometrical shapes called trusses. These trusses are very rigid thus, making the bridge very strong. Because of their strength, truss bridges are often used for railways, as they must be able to support the great mass and the vibrations of the trains. In Conclusion Thanks for listening to my presentation! Advantages of a Truss Bridge There are many types of Truss Bridges that different people have tweaked to make it
their own type.
In the next two pictures, you will see two Truss bridges, a Pony Truss, (the trusses are up) and a Deck Truss (the trusses are down). Both are equally strong and are built by choice. Truss bridges are one of the oldest types of modern bridges. Today engineers have a number of options when it comes to making a choice as to what type of bridge to construct, thanks to modern technology and the resources available to them. Very sturdy and rigid
Withstand heavy weights and vibrations
