The type of construction commonly referred to as fire-resistive and requires that all structural members be noncombustible or limited-combustible materials is:

The main idea is how building construction types specify what materials the structural frame can be made from to slow fire growth. This description — requiring all structural members to be noncombustible or limited-combustible — best fits noncombustible construction. In this type, the entire structural frame is made from materials that do not readily burn, or are only allowable in limited quantities, to minimize fuel for a fire.

Other types differ: Type I is the most fire-resistive and relies on heavily protected framing with high fire-resistance ratings; Type III has noncombustible exterior walls but can use combustible interior structural members; Type IV uses heavy timber for structural members; Type V allows combustible materials throughout. Thus, the construction type defined by noncombustible or limited-combustible structural members is Type II.
