What load is associated with the weight of accumulated snowfall?

The correct answer is associated with the weight of accumulated snowfall as a live load. Live loads are variable loads that can change over time due to environmental factors, such as people, furniture, or in this case, snow accumulation on a structure. Unlike dead loads, which are permanent and constant (such as the weight of the building materials themselves), live loads are not fixed and can fluctuate based on conditions.

Accumulated snowfall can change in weight depending on how much snow falls and how long it remains on a structure before it melts or is removed. This variability characterizes the load as live rather than static or dynamic. Static loads typically refer to loads that do not move or change over time, while dynamic loads include forces that can change due to motion, such as wind or seismic activity. Snow, with its ability to accumulate or dissipate, fits the definition of a live load.
