Step 1: Bracing first truss
Long span trusses are braced securely at the end of the building. Shorter trusses can be supported laterally by a single gable end brace.
The ground braces should be located directly in line with all
rows of top chord continuous lateral bracing, otherwise the top chord of the first truss
can bend sideways and allow the trusses to shift, putting a substantial strain on all connections of the bracing system. Scabs should not be nailed to the end of
the building to brace the first truss. These scabs can break off or pull out, thus allowing a total collapse.
