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.
As far as i can tell there are 27 different types of truss bridges (i.e. Brown truss, Bowstring truss, Kingpost truss, Long truss, and Pratt truss). Hope this helps :D
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.
it is a hybrid between an arch bridge and truss bridge. so it is classified as an arch and truss
Glenville Truss Bridge was created in 1885.
Warren truss bridge
A truss is a diagonal brace which provides structural support for a bridge span by extending between a vertical member and the bridge span.
