Bracing


truss



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.

For the seven bracing steps, please see the following pages:
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.
