Live load is defined as

Live load is defined as

• A. Any load applied to a building other than the dead load
• B. The load from the foundation
• C. The external wind pressure
• D. The structural steel weight

Answer: (A)

Live load is the part of a building’s loads that come from use and occupancy and can change over time. It includes things like people, furniture, and movable equipment—loads that aren’t permanently attached to the structure. This distinguishes it from dead load, which is the permanent weight of the structure itself and fixed elements. So the best description is that live load is any load applied to a building other than the dead load, since it covers all the variable, movable loads arising from how the space is used. The foundation load is part of dead load, wind pressure is an environmental load, and the weight of structural steel is also dead load, not live load.
