Framing & StructuralQuestion 390 of 700
When prefabricated wood roof trusses are delivered to a jobsite, which practice BEST preserves their engineered performance?
a.Install them only per the truss manufacturer's engineered layout and bracing plan
b.Field-cut chords or webs as needed to fit obstructions
c.Notch the bottom chord to run plumbing without approval
d.Store them flat-stacked in mud until installation
Explanation
Trusses are engineered assemblies that must be installed and braced exactly per the manufacturer's layout and bracing design. Field-cutting chords or webs, notching the bottom chord, or storing them improperly all compromise the engineered load path and can void the design and cause failure.
