Exterior walls, bearing walls, floors and supports made completely or partially of wood and is also referred to as wood-frame construction.

• A. Type V
• B. Type I
• C. Type III
• D. Fire resistance

Answer: (A)

Wood-frame construction describes buildings where the structural system—exterior walls, bearing walls, floors, and roof—is made completely or primarily of wood. In building code classifications, this is the wood-frame category. Because the framing is combustible, these structures generally have lower inherent fire resistance than noncombustible types and often rely on protective assemblies or sprinklers to meet fire-resistance requirements. The other options describe different systems (noncombustible framing, masonry exteriors with wood interiors, or a different timber category) and do not match the description of a fully or largely wood construction.
