What does the live load in a building consist of?

The live load in a building specifically refers to the loads that can change over time and are not permanently attached to the structure. This includes movable objects such as furniture, people, equipment, and any other items that occupants might bring into the space. These loads can vary significantly, which is why they are classified as "live" as opposed to "dead" loads, which consist of the weight of the building materials, structural components, and permanent fixtures.

Understanding live load is crucial for structural design, as it helps in determining how much weight a building can safely support as it is occupied or used. This variable nature can greatly affect the dynamics of a structure, especially in residential and commercial buildings where the number of occupants and their belongings may fluctuate.
