What components are included in the definition of "live load"?

The definition of "live load" encompasses those loads that are applied to a structure and can change over time. These include the weight of people, furniture, vehicles, and any other movable items within a building.

Live loads are dynamic and can vary based on how many people are present, the arrangement of furniture, or the presence of temporary objects. Unlike dead loads, which are static and considered as part of the structure’s weight (like walls, roofs, and fixed installations), live loads are subject to change and typically represent what the structure must support beyond its own weight.

Recognizing this helps in understanding how buildings are designed and constructed to safely accommodate the varying demands placed on them by occupants and their belongings, as well as ensuring that safety standards are met. This aligns with the core principles of structural engineering and fire investigation, where understanding load dynamics is crucial for assessing structural integrity during incidents.
