Total length of time during which a Load acts on a member. This information is typically provided in the Construction V3. The goal is to provide clear, concise information for jobsite users so they can implement the handling, installing, restraining and Bracing concepts contained herein more easily. Floor Trusses are more stable during installation because they are built with the wideface of the lumber oriented horizontally.

The Diagonal Brace from the top of the end wall to the top chord of the Truss will impart a vertical force to the Truss Top Chord. This understanding is essential for a safe installation.

For other Loading conditions, contact a Registered Design Professional. Special end wall Bracing design considerations are required by the Building Designer if the Gable End Frame profile does not match the adjacent Trusses. Consult the Building Designer. Graphic art, photographs, sketches, drawings, forms, and table formats that appear in this document have come from many sources, some known and others unknown. Install hip jacks and end jacks at maximum 10′ o.

As with any Connection, the Toe-nailing shall be capable of resisting and transferring the applicable loads. The modification shown in Photo B requires a repair. Also included are appendices containing roof and floor span tables, bbcsi aids, specifications, a glossary, industry associations, and a list of SBCA members.


Shim the joint between the Strongback and Truss to ensure a solid Connection.

Conventional Framing without intermediate supports Figure B distributes the upper roof Load to the lower roof as a concentrated line Load acting along the valley created at the intersection of the two roofs. Work shall be installed in accordance with the approved construction documents, and any changes made during construction that are not in compliance with the approved construction documents shall be resubmitted for approval as an amended set b33 construction documents.

Please consult a Registered Design Professional. Trusses have flat Bottom Chords and are spaced 4′ to 12′ on-center o. n3

No camine sobre entramados no apuntalados. The actual unit weight of a Truss depends on many factors including the size and species of bsci, the moisture content of the lumber and the Truss configuration.

Bracing of trusses – Riverside Truss

A side view representation or outline of a Truss. Doing so leaves the Truss in an unstable condition and places the installation crew in danger. Submittal documents consisting of construction documents, statement of special inspections, geotechincal report and other data shall be submitted in two or more sets with each permit application.

The horizontal or sloped structural system defined by the ceiling plane acting to transmit lateral forces to the vertical resisting elements. Maximum axial tensile and compression forces in the Truss members; For 2×6 or greater Lateral Restraint and Diagonal Bracing, use a minimum of three nails per Connection.

The method used to frame a valley will affect how the Loads from the upper roof are distributed to the supporting Trusses, and therefore, how these Trusses are to be designed. It is of- ten more structurally efficient for multiple-ply Webs and provides easier nailing because it is applied to a wide-face of the Web. See also Ground Bracing and Figures B and 4, page Electronic media documents are permitted to be submitted where approved by the building official.

Bracing is typically provided by adding Diagonal Bracing within the same plane of the Lateral Restraint or by anchoring the Lateral Restraint to a lateral force resisting member such as a shear wall. The Diagonal Bracing should be attached as close to the Top and Bottom Chord Plane as possible and to each web that it crosses.


Limit stack heights to those provided in Table B and stacking periods to approximately one week, unless alternative information is provided by the Building Designer, Truss Designer or Truss Manufacturer.

The Gable End Trusses are stabilized against rollover by connecting the Top and Bottom Chords to the end wall columns or engineered Bracing system.

Top Chord Plane 2.

Providing stability against unintended movement or motion. Trusses are used in an engineered building system. The methods and procedures outlined in this document are intended to ensure that the overall construction techniques employed will put the Trusses into place SAFELY. Minimum Nail Size 10d 0. Position stacks of materials flat with the longest dimension perpendicular to the Trusses as shown.

Visit the SBCA website at sbcindustry. Trusses should be unloaded as close to the Building site as possible to minimize handling. Accordingly, the employer has the burden of establishing that it is appropriate to implement a fall protection plan which complies with DO NOT store bundles upright vertical unless properly braced to prevent toppling.

Valley Set frames spaced at more than 24″ o. Thus, WTCA and TPI expressly disclaim any responsibility for damages arising from the use, application, or reliance on the recommendations and information contained herein.

The Construction Documents shall be readily available on the jobsite and only the approved set shall be used. Vertical depth of the Truss at the outside face of bearing. Anchor Trusses securely at bearing points. Bottom Chord Plane 3.

It is composed of vertical and diagonal members providing support for the installed Trusses from the earth, floor, foundation or slab. Short Member Temporary Lateral Restraint: The larger the diameter of the nail shank, the greater the v3 to withdrawal and lateral Loads.
