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.
The pratt truss is efficient because the longer diagonal members are in tension and the shorter vertical members are in compression. Members in tension fail because the member is stressed to materials maximum stress capacity. Members in compression usually fail through buckling because of instability long before the materials maximum stress is reached.
