Which load describes the weight of the building itself and permanently attached elements?

• A. Dead load
• B. Live load
• C. Impact load
• D. Fire load

Answer: (A)

The weight of the building itself and permanently attached elements is the dead load. This is the constant self-weight that the structure must support at all times, regardless of how the building is used. It includes the weight of structural members (beams, columns, slabs), walls, floors, fixed finishes, and permanently attached equipment or fixtures. Because this load stays the same, engineers calculate it into the design to ensure the frame can safely carry both the self-weight and other loads. In contrast, live load varies with occupancy and use (people, movable furniture), impact load covers short-term dynamic forces, and fire load refers to the potential energy from combustibles in a fire.
