Fire resistive construction has structural members of protected noncombustible or limited combustible materials.

Fire resistive construction has structural members of protected noncombustible or limited combustible materials.

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

Answer: (B)

Fire-resistive construction is about protecting the building’s structural frame so it can endure fire for a specified period. This is achieved by using structural members that are noncombustible or only lightly combustible and surrounding them with fireproofing or protective encasings. The idea is that the frame helps resist heat long enough to maintain stability and allow safe evacuation, which is why this approach aligns with the most fire-resistant building type. In the common classification, that level of protection corresponds to the most fire-resistive type of construction. Type I buildings rely on protected, noncombustible or limited combustible structural members to achieve high fire resistance ratings. Other types use different material strategies: Type II is noncombustible but not necessarily designed for the same fire-resistance performance; Type III and Type V include combustible components in the structure or interior, or rely more on compartmentation and other features rather than protected framing.
