Temporary load that the roof structure must be designed to support, as required by governing building codes. Live loads are generally moving and/or dynamic or environmental, (e.g., people, installation equipment, snow, ice or rain, etc.)
Loads on a member that are not permanent and are likely to be moved at some point in the life of the structure They can be loads produced by the use and occupancy of the building These loads do not include dead load, wind load, snow load, or seismic load
a dynamic load (such as traffic) that is applied to a structure suddenly or that is accompanied by vibration, oscillation, or other conditions that affects its intensity
The weight of everything in a building, including people and furniture, which it is built to support, versus the dead weight (fixed) of the building itself
The moving load or variable weight to which a building is subjected, due to the weight of the people who occupy it, the furnishings and other movable objects
The variable weight per square foot to which a building is subjected Typical suburban live-loads may be in the 50-70 lbs per square foot range, while class A high-rises may offer 75-120 lbs per square foot This measurement may be critical for heavy file or equipment areas
