In terms of load, what specifically is not considered a live load?

A live load refers to the weight of the movable objects on a structure, which can include people, furniture, and other temporary loads that can change over time. The roof structure is considered a part of the permanent construction of a building and is classified as a dead load rather than a live load. Dead loads are static forces that remain constant over time, such as the weight of the building materials themselves.

Occupancy and furniture are directly associated with live loads, as they can fluctuate based on how many people are present and how furniture is arranged. Environmental effects, while they may influence a structure, generally describe conditions like snow accumulation or wind, which can also contribute to different types of loads but do not fit the specific definition of live load. Thus, the roof structure stands out as it pertains to the building's foundational elements and overall stability, distinguishing it from the dynamic nature of live loads.
