Step 5: Temporary bracing of bottom chord plane
To hold the proper spacing of the bottom chord, continuous lateral bracing at no greater than 2.4
to 3 m on centre along truss length is used for the full length of the building, secured to the
bottom chord. Diagonal bracing at 45° between laterals will stabilize this bracing system. The
bracing is usually left in place to become part of the permanent bracing system. Once the
temporary bracing is properly installed, permanent bracing and decking can be installed.
Concentrated loads from sheathing or roofing material should not be placed on trusses. These
loads should be spread evenly over a large area to prevent overloading of any one truss. A limit of
eight sheets of plywood should be placed on any pair of trusses and should be located adjacent
to the supports.
