What does the term "dead load" refer to in construction?

The term "dead load" in construction specifically refers to the weight of the permanent or static components of a building. This includes all the materials that are permanently affixed to the structure, such as beams, walls, roofs, and other structural elements. Option A effectively captures this definition, as it mentions the weight of things attached to the building.

Dead loads are calculated to ensure that a structure can support its own weight in addition to any other loads that may be applied. This load is constant over time, as opposed to live loads, which can fluctuate (like the weight of people or furniture).

Understanding dead load is critical for fire investigators because the weight and stability of structural components can significantly affect fire behavior within a building, potential collapse scenarios, and the overall safety of firefighting operations during an incident.
