Connection between the roof or floor framing members e. Ground Bracing not shown for clarity. Vertical depth of the Truss at the outside face of bearing.
The same Bracing can often be used bsci support both functions. Submittal documents consisting of construction documents, and other data shall be submitted in two or more sets with each application for a permit.
Framing member installed on the edge of the exterior perimeter, usually tying the ends of floor Trusses together. Worker attention is often directed upward, even while moving around.
Other attachment requirements may be specified by the truss designer or building bcs. The Truss Designer and Truss Manufacturer shall be notified prior to manufacturing the Trusses if the spacing and thickness of the restraint and Bracing between the supported and supporting Trusses will be different than what is shown on the TDD.
The same bracing can often be used for both functions. The sections of this book are available as B-Series Summary Sheets. This is not required bb3 the multi-ply girder is fastened by the Truss Manufacturer at the manufacturing plant, as the in-plant QC program and third-party inspection process assures that the fastening is performed per the requirements of the TDD.
Are the bearing supports straight along their length, and bcdi where they should be parallel? Toe-nailing through a Metal Connector Plate of a Truss does not adversely affect the uplift capacity of the Connection, provided the Truss Plate bbcsi lumber are not damaged during installation.
One row of CLR required on each of these two Webs. Top chord sheathing not shown for clarity.
BCSI fulfills the policies of the two associations to promote handling, installing and Bracing guidelines for Metal Plate Connected Wood Trusses MPCWT that are simple, safe, proven methods consistent with good framing construction practices in the field. All of the care and quality involved in the design and manufacture of Trusses is jeopardized if the Trusses are not properly handled, hoisted, installed, restrained and braced.
Erect Trusses using the design spacing indicated, keeping the Trusses vertical and parallel bcis one another. Documents Flashcards Grammar checker. Nominal lateral design capacities have been adjusted by the Toe-nail factor and represent normal Load duration values. CLR required only 60′ Out of Plane Max.

It tells the installer to check the Truss Design Drawing for more specific bcwi. Non-Load bearing walls can transfer loads, if large construction Loads are applied above them. Attach securely at all bearings, shimming bearings as necessary. The Truss Manufacturer and Truss Designer rely on the fact that the Contractor and crane operator if applicable are capable to undertake the work they have agreed to do on a particular project.
If the two members are of different species, use the species with the lowest specific gravity to determine the lateral load capacity of the Connection.
Install per screw manufacturer and Truss Designer requirements and specifications. Are the tops of all bearing supports at the correct eleva- tion?
Top Utilice chord porting truss or restraint. Nominal lateral capacities are based on framing conditions depicted in Figures B and They do not have the structural strength to support a worker safely while oriented flat.
Structural horizontal members attached perpendicular to the Truss Top Chord used to provide Lateral Bczi to the Top Chord and to support and transfer the roof Loads to the Trusses. Make sure the area remains clear of plumbing, electrical, mechanical runs, etc.
Distance or void between two adjacent Trusses in a row of Trusses. Properly connect the Truss to each support. Install all remaining corner and end jacks with all permanent Truss-to-bearing Connections e. Documents, is responsible for all Gable End Frame Bracing, including the Bracing member size and locations, attachment bcsl Trusses, gable end sheathing, and fastener size and locations including any mechanical Connectors required.

If the hip Girder Truss consists of multiple plies, it is much easier to fasten the plies together and install the end jack hangers if required on the ground before lifting the Girder Truss into place. If the contractor believes it needs assistance in some aspect of the construction project, it should seek assistance from a competent party.
Truss with Top and Bottom Chords with equal slopes. WARNING The handling, storing, installing, restraining and Bracing of Trusses requires specialized training, clearly implemented procedures, and careful planning and communication among the Contractor, all installation crews and any crane operators.
This includes the use of nails, bolts, lag screws, metal straps, or Connectors. Prior to component installation, the documents should be examined and disseminated to all appropriate personnel, in addition to proper training and a clear understanding of the installation plan, any applicable fall protection requirements, and the intended restraint and bracing requirements.
