According to PD 1096, which construction type is typically characterized by the use of steel and masonry?

The correct construction type characterized by the use of steel and masonry, according to PD 1096, is Type IV. This classification pertains to structures that combine steel framing with masonry elements, which provides a balance of strength, durability, and fire resistance.

Type IV construction typically involves materials such as reinforced concrete and steel, which contribute to the structural integrity of the building while also allowing for a variety of architectural designs. This type is recognized for its ability to withstand various environmental conditions and has specific requirements regarding fire resistance based on its materials.

Structures classified as Type I generally consist of non-combustible materials throughout, whereas Type II buildings may use non-combustible materials in some sections but still include combustible elements. Type III constructions are known for having external walls of non-combustible materials while the interior may contain combustible materials. Each of these types has distinct features that differentiate them from Type IV, which most directly correlates with a combination of steel and masonry.
