They Commonly Are Used in Covered Bridges, Railroad Bridges, and Military Bridges.
What Types of Bridges Were Built Using the Truss Design?
A truss bridge is a bridge composed of connected elements (typically straight) which distribute the load across the structure.
Truss bridges were first used during the early 19th century and became increasingly popular as a means of spanning large distances with a minimum of materials.
The most common type of truss bridge is the Pratt truss, which uses a combination of tension and compression members to support the bridge deck.
The use of the truss design for bridges dates back to the 18th century, when carpenters and architects began experimenting with different ways to distribute the weight of a bridge across its span.
The first known use of the truss design was in a bridge built over the River Severn in England in 1793. The bridge was designed by Timothy Hackworth, an English engineer, and it used a truss design to support the bridge deck.
The truss design quickly gained popularity, and by the mid–19th century, truss bridges were being built all over the world.
The most common type of truss bridge is the Pratt truss, which was first patented in 1844 by Caleb Pratt, an American engineer.
Pratt‘s design used a combination of tension and compression members to support the bridge deck, and it soon became the
