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
- keep the trusses plumb, and
- assure correct truss spacing.
Permanent bracing is required to ensure that the trusses are integrated into the overall
building structure to:
For the seven bracing steps, please see the following pages:
For more details consult:
- prevent buckling of web members loaded in compression
- share loads between adjacent trusses,
- transfer lateral forces to diaphragms, and
- restrains overall lateral displacements.
