The geometric shape used in truss bridges is the triangle.
In the United States, a premium was placed on inexpensive design, which led to the predominance of the simple triangulated truss design (first used with wooden bridges and later for iron bridges).
A Warren Truss Bridge is used to cross certain obstacles. The Warren Truss bridge is Constructed with equilateral triangles so, this relieves of Compression and Tension.
The hypotenuse. It is used to measure height. Very simple equation.
A tubular truss is a truss that has struts and chords that are composed of cylindrical tubes or pipes. They are used for large constructions including factories, shopping malls, and industry worksheds.
Single pitch truss is used for example in storage buildings, machine shelters and in residential buildings. Single pitch truss roof enables directing the snow away from passageways. Width of the truss bottom chord can be maximum 20 meters.
A truss gusset is a metal plate used to connect the members of a truss together. It helps distribute the forces evenly across the truss, increasing its stability and strength by preventing the members from moving or shifting. This reinforcement ensures that the truss can support heavy loads and maintain its structural integrity.
Caleb and Thomas Pratt invented the truss bridge in 1844. Some of the materials that have been used in truss bridges are timber, steel, reinforced concrete, and iron.

Single pitch truss is used for example in storage buildings, machine shelters and in residential buildings. Single pitch truss roof enables directing the snow away from passageways. Width of the truss bottom chord can be maximum 20 meters.
It uses a K-truss style that is rarely used outside of the Great Plains.
The type of bridges are: -truss bridge -arch bridge (truss arch bridge) -suspension bridge (suspension truss bridge) -cantilever bridge
