A Pratt flat truss is a type of truss that is characterized by its diagonal members sloping down towards the center of the bottom chord. This type of truss is most commonly used for bridges and other structures that need to support a large load over a long span. The diagonal members in a Pratt flat truss are under tension, while the vertical members are under compression. This allows for the use of lighter materials in the construction of the truss, which can save on overall costs.
The Flat Pratt Truss is configurable in a range of sizes with typical spans between 24’-72’ (7.3-21.9 m) and overall heights of 1’4”-9’ (.41-2.44 m). The thickness of wood trusses is commonly 1.5”, 3”, or 4.5” (3.8, 7.6, 11.4 cm).
