Description
Description

A bowstring truss is a type of truss that has a curved top chord and a flat bottom chord. The curved top chord is under compression, while the flat bottom chord is under tension. The truss is held together by a series of diagonal struts and ties. Bowstring trusses are often used in roofs and bridges, as they can span long distances without the need for additional support.

The Bowstring Truss is configurable in a range of sizes with typical spans between 30’-60’ (9.1-18.3 m) and overall heights of 5’-30’ (1.52-9.14 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.
