A Pratt truss is a type of truss that uses diagonal members that angle towards the center of the upper chords. This design makes the truss very strong in compression, which makes it ideal for bridges and other structures that need to support a lot of weight. Pratt trusses are also relatively lightweight, which makes them easy to transport and assemble.
The Pratt Truss is configurable in a range of sizes with typical spans between 24’-60’ (7.3-18.3 m) and overall heights of 4’-30’ (1.22-9.14 m). The thickness of wood trusses is commonly 1.5”, 3”, or 4.5” (3.8, 7.6, 11.4 cm). Trusses have a pitch ratio typically between 1:1 to 1:6.
