Which of the following is considered a structural load?

The weight of the roof system is considered a structural load because it directly contributes to the overall load that the building's structural framework must support. Structural loads are critical factors that engineers and architects must account for when designing a building to ensure safety and stability. The roof system’s weight exerts downward force on the supporting walls and foundation, influencing the design and materials used to create a resilient structure.

Other elements mentioned, such as furniture arrangement, occupant loads, and decorative elements, play a role in the use of a building but are typically categorized under live loads or non-structural components rather than primary structural loads. These other factors are important for municipalities and building codes, but they do not impact the core structural integrity in the same way that the roof's weight does. By focusing on the loads directly associated with the building's construction, it is clear why the weight of the roof system is identified as a fundamental structural load in building design and inspection.
