A solid member placed between structural members, usually at the bearings, to provide lateral support. Glossary of Terms iagonals: When using Toe-nails to attach the Top or Bottom Chord of a Truss to the side of a Girder Truss or wood beam, the number of nails used is bcsj limited to a maximum of three Toenails for 2×4 chords and four Toe-nails for 2×6 chords. Columns laminated columns or posts are embedded in the ground or attached to a foundation using the method specified by the Building Designer.

Are all as-built dimensions the same as those depicted in the Construction Documents? Owner of a Building, or the person who contracts with the Owner, bcdi constructs the Building in accordance with the Construction Documents and the Truss Submittal Package. Stopping in the middle of the Truss installation to straighten and brace these supports is dangerous. Install remaining Hip Trusses. The registered design professional in responsible charge shall be responsible for reviewing and coordinating submittal documents prepared by others, including phased and deferred submittal bcsk, for compatibility with the design of the building.
Officer or other designated authority charged with the administration bdsi enforcement of the building code, or a duly authorized representative. A publication of the American Wood Council AWCthis standard is referenced by model building codes for structural design of wood Buildings. Save time by applying Structural Sheathing immediately.

A written, graphic or pictorial depiction of the required fix to an altered or damaged Truss or part. The Connection at the top is important during Truss installation as it helps bcsu stabilize the Top Chord of the Girder Truss. If soil conditions are poor, it may be necessary to add a Horizontal Tie Member at ground level to connect the lower end of the Ground Brace Vertical and the lower end of the Ground Brace Diagonal.
Proprietary metal reinforcement products and stacked web products are also viable alternatives.
Each Summary Sheet condenses the information contained in the corresponding section of this book into a few pages that emphasize the main points using a graphical representation of the text as fully as possible. Position the hip Girder Truss on the bearing walls at the specified end wall setback. Tight-fitting coverings are not recommended, since they can trap moisture. Also referred to as a step-down Truss.
Review the Truss Design Drawings to determine the proper number of plies and the correct attachment methods to be used at the jobsite. Position the Diagonal Brace s to cross the webs in close proximity to each Lateral Restraint to minimize the out-of-plane bending forces in the web.
The Truss Designer will specify the number of members in a multi-ply Girder Truss. Nail each additional ply in accordance with the specified schedule found on the TDD.
Bracing of trusses – Riverside Truss
In the photo below, a 4-ply parallel chord Girder Truss is supported at one end by a 3-ply Girder Truss with a pitched Top Chord. Splices for Ground Bracing, if constructed with wood members, should have a minimum three-foot overlap nailed with a bcsu of ten 16d 0.
Worker attention is often directed upward, even while moving around. Never exceed stack heights per Table B, page 53, unless alternative information is provided by the Building Bcsl, Truss Designer or Truss Manufacturer. Braces lap two rows of Lateral Restraint if Diagonal Brace is spliced.
T he ground stake should be driven to a capacity which will resist one and one half times the cumulative lateral bracing force P as determined from DSB Truss heels are connected to columns or headers i. Other Truss types are expressly excluded. Stack heights assume shortterm duration of Load. Fail to install Diagonal Bracing. Ring, or screw shaped configuration of a nail shank.
Person responsible for vcsi preparation of the Truss Design Drawings. Valley Set frames Figure B on page 35 spaced at 24″ o.
Locate the Spreader Bar at or above mid-height of the Truss to prevent overturning. Some chord and Web members not shown for clarity. DO NOT inhabit or store anything of value in temporarily b structures.
N3 is composed of vertical and diagonal members providing support for the installed Trusses from the earth, floor, foundation or slab.
Strongbacking is generally attached to vertical Webs or scabs at specified intervals and bdsi. The Truss members form a rigid, planar, structural component and are usually assembled such that the members form triangles.
If the bcsl members are of different species, use the species with the lowest specific gravity to determine the lateral load capacity of the Connection.
