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. The modification shown in Photo B requires a repair.
All plies of a multi-ply Girder Truss shall be attached per the fastening schedule on the TDD before attaching any framing members or 3b any Loads. Horizontal distance between outside edges of exterior bearings.
A good hoisting device and Spreader Bar can photo b provide support and be a real time saver. Person responsible for the preparation of the Truss Design Drawings.

Repeat the process with sets of four Trusses until all of the remaining Trusses in the Building run have been installed. This bracing can be provided in a number of ways including: Rigging Equipment Use materials such as slings, chains, cables and nylon straps of sufficient strength to carry the weight of the Truss or Truss bundle.
Installation of Trusses can be dangerous, particularly long span Trusses i. The use of alternative measures shall be used in conjunction with conventional fall protection systems, and the use of bcsii methods shall be as limited as possible.

Valley Set frames spaced at more than 24″ o. DO NOT inhabit or store anything of value in temporarily braced structures.
Connection between the roof or floor framing members e. Series of Trusses of the same span and Overhang that decrease in height to h3 the end slope of a hip roof system.
Out of Cbsi Max. Specialized structural Building products designed, engineered and manufactured under controlled conditions for a specific application. Construction documents shall show the size, section and relative locations of structural members with floor levels, column centers and offsets dimensioned.
Do not install Trusses on anchors, hangers, tie-downs, seats or bearing ledgers that have temporary Connections to the bcei structure. Set of triangular components used to frame the shape of dormers and to complete the roof framing where Trusses intersect at perpendicular corners.
If not, corrective actions shall be taken prior to Truss installation. Publication of SBCA, this reference book on Metal Plate Connected Wood Trusses has been updated with the most current industry standards and building codes, history, design, fabrication, testing, quality assurance, Connection details, fire resistance assemblies and much more.
This Bracing is referred to as permanent stability Bracing and is the responsibility of the Building Designer. Permanent Lateral Restraint and Bracing is needed for the proper performance of individual Trusses within the roof or floor system.
Framing member installed on the edge of the exterior perimeter, usually tying the ends of floor Trusses together. If the Truss Bottom Chord and wall plate are different species, use the species with the lowest specific gravity to determine the lateral Load capacity of the fasteners.
Temporary Diagonal Bracing repeated entire length of Building.
Bracing of trusses – Riverside Truss
Are the bearing supports straight along their length, and parallel where they should be parallel? Trusses are engineered components that can be damaged through mishandling, jobsite modification or improper installation.
Submittal Documents typically include, but are not limited to: The registered design professional in responsible charge shall be responsible for reviewing and coordinating submittal documents prepared by others, including phased and deferred submittal items, for compatibility with the design of the building. The portion of the Top Chord between pitch breaks shall be restrained at intervals not exceeding the lengths given in Table B see Figures B, 7 and 10, pages Likewise, after this first set of Trusses is adequately Diagonally Braced, the remaining Trusses installed rely on this first set for stability.
Some installers lift the first five Trusses one at a time and restrain, brace and sheath as they go. Some of the more pertinent subsections include, in part: Wear personal protective equipment for the eyes, feet, hands and head when working with Trusses.
T o help transfer large Bracing forces into the roof and ceiling Diaphragms, dimension lumber Blocking may need to be installed between the Trusses on either side of the Diagonal Brace location as shown in Figure B Erect Trusses using the design spacing indicated, keeping the Trusses vertical and parallel to one another.
