Which statement about Type V construction is true?

Which statement about Type V construction is true?

• A. Noncombustible exterior walls with heavy timber frame
• B. Wood frame construction
• C. Masonry walls and steel roof
• D. Reinforced concrete only

Answer: (B)

Type V construction is defined by using wood framing as the primary structural material. This makes the entire structure combustible, with framing, floors, and many interior assemblies typically built from wood. Fire resistance is provided mainly by fire-rated assemblies rather than the inherent properties of the frame, so Type V buildings generally have lower inherent fire resistance than the other types unless specifically added. The other descriptions reference noncombustible systems or different materials (like heavy timber framing, masonry walls, or reinforced concrete), which do not fit Type V. So, wood frame construction is the correct description for Type V.
