Which term refers to an inert, inactive load primarily due to the structure's own weight?

The term that refers to an inert, inactive load primarily due to the structure's own weight is the dead load. Dead loads are the static forces that are always present and contribute to the structure's overall weight, including the weight of structural elements such as beams, columns, walls, roofs, and any permanently attached fixtures. These loads remain constant over time and do not change with conditions or occupancy, making them crucial for structural calculations.

Understanding dead loads is fundamental in engineering design because they contribute significantly to the overall load that a structure must support. Accurate measurement and accounting for dead loads are critical to ensure structural stability and safety. Other load types, like live loads, dynamic loads, and impact loads, are variable and can change depending on usage, environment, or external forces, contrasting with the consistent nature of dead loads.
