Wood frame construction is commonly referred to as which construction type?

• A. Type I
• B. Type II
• C. Type III
• D. Type V

Answer: (D)

The main idea is that construction types categorize buildings by what their structural frame is made from and how fire-resistant that frame is. Wood frame construction falls into Type V, the category designated for structures built with wood or other combustible framing. This type is typical for residential and many small buildings because the framing itself is combustible, which affects fire behavior and code requirements. The other types reflect greater fire resistance or noncombustibility: Type I is fire-resistive with protected systems, Type II uses noncombustible materials, Type III has noncombustible exterior walls with interior elements that can be combustible, and Type IV uses heavy timber framing but is a distinct, less common category.
