Wood Trusses are supporting structural elements which have a series of members acting in both tension and compression. They are utilized for roof or floor framing construction and are available in a variety of shapes and sizes. They are manufactured in controlled shops/plants and highly efficiently and most commonly with wood member sizes of 2×4 and/or 2×6. Trusses are fabricated by cutting to size and joining the members at toothed plate connections. The primary design factors that Architects will consider is the roof pitch, overall span, and overhang detail. It is commonly the truss manufacturers responsibility to utilize a known design to handle the live, dead, wind, and seismic loads or have an engineer custom design them. Shop drawings are commonly produced and submitted to the project architect/engineer for review. Pre-manufactured wood trusses will typically consume less wood than field framing and are assembled more efficiently in a plant environment often for lower workers wages than in the field. Trusses can be set with a crane relatively quickly in comparison to field labor from scratch, but some field installed blocking, joints, and assembly-joining carpentry will still commonly be required.
