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.Tuesday, August 31, 2010

K Truss.
In the K Truss, the length of the members that undergo compression is reduced. The design of this bridge is complicated and is considered to be one of the hardest bridges to build.

Warren Bridge
The Warren bridge consists of longitudinal members joined only by cross angled members.
The load on this bridge causes compression and tension in the center of the bridge.

Howe Truss
From 1840 to about 1870 the standard railroad bridge was the Howe truss, a rectangular trussed frame of wooden diagonals and vertical iron tie rods. This bridge was invented by William Howe, a farmer turned inventor.
