The design is based on matching the configuration of existing trusses. The remainder of the structure Is Intended to be constructed using the Conventional Light -Frame Construction provisions of the building code. Our review Is limited to the design of the trusses themselves. Please note that without the stamp of a licensed engineer or architect on the drawings, the owner and contractor cavy full liability for accuracy of the design and compliance with provisions of the building code. Building permits and design documents for specific elements such as roof trusses and floor Joists do not reduce this liability as the parties preparing these documents are not responsible for thorough review of the overall structure. It is also important to recognize that the Conventional Light - Frame Construction provisions of Chapter 23 Division IV require engineering design of the gravity Toad system when loads exceed those lusted for dimensional lumber framing. Design services performed by roof truss and floor Joist suppliers do not generally Include portions of the gravity load system which do not supply. The truss Is to be constructed using 2x4 Number Two Douglas Flr-Larch top and bottom chords and 2x4 Stud Grade Spruce -Pine -Fir, Hem -Fir or Douglas Fir -Larch web members. The total overall truss length Is 28'-0' supported by wood framing at 26'-0" outside dimensions with flat bottom chords and top chords sloped at 2.75:12 to a peak at 3'-3 Y2 at mid -span. Webs conned top and bottom chords vertically at center and diagonally starting at the bottom chord center intersecting alternately top and bottom chords at 4'-4' maximum on center spacing along each chord. The chords are attached to each other at the support, peak and splices and to web members with 5/8' plywood gusset plates both sides. The gusset plates must be attached with 27-8d rinkshank nails both sides into each chord segment et supports and splices and 5-8d ringshank nails both sides into each piece at peak and web member connections. If you have any questions or need any additional Information, please call. Sincerely, Brett Danielson, P.
