Step 7: Permanent lateral bracing to web member or bottom chord plane (all buildings)


Permanent bracing in web and bottom chord planes is usually applied as temporary bracing
(Steps 4 and 5). Lateral bracing of compression web members is a typical method to prevent
buckling. The method used to anchor the lateral bracing must be specified by the designer.
Bottom chord bracing helps to maintain truss spacing, also can resist buckling caused by stress
reversal. Multiple-bearing or cantilevered trusses can result in compressive forces in bottom
chords.
