Framing & StructuralQuestion 327 of 700
What is the purpose of permanent lateral bracing on the web members of long-span roof trusses?
a.To carry roofing weight directly to the ground
b.To prevent the slender web members from buckling and to stabilize the truss system
c.To serve as a walking surface for workers
d.To replace the need for a ridge board
Explanation
Permanent web bracing ties the truss webs together so slender compression webs cannot buckle sideways and the truss system stays stable under load. It does not carry roofing to the ground, is not a walkway, and is unrelated to the ridge board, which trusses generally do not use.
