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.
