Common--Truss configurations for the most widely designed roof shapes. Mono--Used where the roof is required to slope only in one direction. Also in pairs with their high ends abutting on extremely long spans with a support underneath the high end. Scissors--Provides a cathedral or vaulted ceiling. Most economical when the

2023年6月21日 · The Scissors 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.
Roof Truss Calculator
Input the roof length, the on-center spacing (the distance between the middles of two neighboring roof trusses), and the roof truss calculator will return the number of roof trusses needed. Our tool can also figure out the approximate roof truss cost.
builders used timber trusses to span over their vaulted stone ceilings to support the cathedral roofs above. In a few rare instances, such as Westminster Hall, the trusses were embellished with ornate carvings and left exposed. In North America, early meetinghouses and churches were built with timber roof trusses in the European tradition.

The representative truss span tables provided in this appendix are included in order to give architects, builders, designers and engineers an idea of the truss spans available for a particular load condition, load duration, lumber type and truss configuration.
Trusses can span great distances, creating larger open spaces below unobstructed by columns and partitions. Roof truss systems are manufactured in controlled environments, so there's less chance of warping, shrinking, and twisting of lumber. Trusses also save timber resources by reducing the amount of wood waste generated during construction.
