At ceiling level, ceiling joists rest directly on top of what structural element?

• A. Wall Plates
• B. Beams
• C. Girders
• D. Trusses

Answer: (A)

Ceiling joists need a sturdy, level bearing surface at their ends. In typical wood-frame construction, that surface is the top wall plate—the horizontal member on top of the wall studs. The wall plate provides a flat seat for the ends of the joists and distributes their load into the studs, helping keep the wall straight while transferring the ceiling (and any floor above) load down through the wall system. Beams or girders are larger support members that may carry loads over longer spans, and trusses have their own bearing arrangements, but the standard resting point for ceiling joists at ceiling level is the top of the wall plate.
