Pratt truss

The Pratt truss is named after Thomas and Caleb Pratt, Boston railroad engineers who patented the design in 1844. The Pratt and its variations are the most common design of metal truss bridges. On a basic Pratt truss, the diagonals slope toward the center of the bridge, do not cross any verticals, and are approximately parallel. The top chord is straight and parallels the lower chord. The panels can have sub-divisions - or verticals and diagonals that don't reach from the top to bottom chord, though this can be considered a variation of the basic type. There are many variations, or sub-types of the Pratt truss, some of which have their own name including Parker, camelback, Pennsylvania, Baltimore, and others. It is used in bridges as a through truss, pony truss, and deck truss.
