Bracing
Trusses must be braced to ensure safety and performance. For more details on the
design responsibilities of the truss designer, the building designer and the contractor
consult the
TPIC-2007 Standard - Section 4 Member Design Procedure.
Temporary Bracing
Temporary bracing is required during erection to enable the truss assembly to:
- withstand the gravity forces of its own weight,
- resist wind loads during construction,
- support temporary construction dead loads such as the weight of sheathing and roofing materials
- keep the trusses plumb, and
- assure correct truss spacing.
Permanent Bracing
Permanent bracing is required to ensure that the trusses are integrated into the overall
building structure to:
- prevent buckling of web members loaded in compression
- share loads between adjacent trusses,
- transfer lateral forces to diaphragms, and
- restrains overall lateral displacements.
