Truss is used because it is very rigid structure and it can transfer the load from a single point to much wider area. Truss bridge, bridge with its load-bearing structures composed of a series of wooden or metal triangles, known as trusses. Bending leads to compression in the top chords (or horizontal members), tension in the bottom chords, and either tension or compression in the vertical and diagonal members, depending on their orientation. Ki ng post truss, Bowstring truss, Queen post truss, Flat truss, Lenticular truss are some other forms of trusses in the use of the industry. _ TRUSS BRIDGES Armtec offers strong, safe and durable pedestrian and vehicular truss bridges in a variety of styles. 4.

Trusses are an extremely strong, well-accepted, cost-effective option for the construction of various structures. In general, the larger and shallower the arch, the greater the effects of tension and need for abutment support. Trusses are comprised of many small beams that together can support a large amount of weight and span great distances. A horizontal beam supported at its ends comprises the structure of a beam bridge (span a distance of approximately 200 feet).! They are often chosen for their strength and appearance.
