What type of construction is defined by structural members made of noncombustible or limited combustible materials?

1. Type II

2. Type III

3. Type I

4. Type IV

The correct answer is: Type I

The definition provided refers to Type I construction, which is characterized by the use of noncombustible or limited combustible materials for its structural components. This type of construction is often used in high-rise buildings, where fire safety and structural integrity are paramount. Type I construction typically utilizes materials such as reinforced concrete and steel, which can withstand high temperatures and do not contribute to the spread of fire. In contrast, the other types of construction involve varying degrees of combustible materials—Type II allows the use of some noncombustible materials but does not require them throughout, Type III involves a mix of noncombustible and combustible materials, and Type IV is known as heavy timber construction, which prominently features wood. Understanding these distinctions is essential for fire safety compliance and assessing the fire-resistance ratings of various structures.
