"TEMPORARY AND PERMANENT BRACING"
Temporary Erection Bracing:
Trusses are not marked in any way to identify the frequency or location of temporary bracing.
All temporary bracing shall comply with the latest edition of commentary and recommendations for Handling, Installation and Bracing of Metal Plate Connected Wood Trusses (HIB), published by the Truss Plate Institute, or as specified in the Construction Design Documents prepared by the building designer.
Permanent Truss Bracing:
Permanent bracing of the roof and/or floor truss system is the responsibility of the building designer and should be shown on all the Construction Design Documents. Permanent bracing locations for individual compression members of wood trusses are shown on the Truss Design Drawings, and shall be installed by the building or erection contractor. This bracing is needed for the proper performance of individual trusses with in the roof or floor system.
The design and connection of the bracing to the truss and then to the overall building system is the responsibility of the building designer and is in addition to the permanent bracing plan, also specified by the building designer.
Special Design Requirements:
Special design requirements for wind bracing, portal bracing, diaphragms, Shear walls or other load transfer elements and their connection to wood trusses must be considered separately by the building designer, who shall determine size, location and method for all bracing as needed to resist the forces.
Improper Storage, Handling, Erection and Bracing of the trusses in the truss system may cause a collapse of the truss system or of the structure itself, Which may result in Serious Injury or Death.
