Bracing

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 design procedures page iii

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.
