Type V Wood Frame construction is characterized by which of the following?

Type V Wood Frame construction is characterized by the fact that all walls and structural supports are either partially or completely made of wood. This construction method is prevalent in residential buildings and emphasizes using wood as the primary material, which affects both the structural integrity and fire behavior of the building. The reliance on wood for both the framing and the walls can significantly influence firefighting strategies, as wood's combustion characteristics differ from that of other materials like steel or concrete.

The other characteristics mentioned in the other choices do not accurately define Type V construction. Heavy timber is more characteristic of Type IV construction, which emphasizes the use of large timbers rather than smaller wood framing. Foundation walls being made of concrete refers to a different aspect of structural construction that is not exclusive to Type V. Lastly, the presence of steel components as the sole material for interior walls would indicate a different construction type, such as Type II or Type I, rather than Type V, which is predominantly wood-based. Understanding this categorization is essential for fire safety and firefighting tactics associated with various types of building construction.
