What is the ground snow load in Duluth?

In Duluth, Minnesota, the ground snow load is established based on historical data and the structural requirements for buildings in that region, taking into account the typical snowfall and its density. The correct answer of 60 psf (pounds per square foot) is due to Duluth's geographical location and climate conditions, which result in significant snow accumulation during winter months.

This 60 psf figure reflects the maximum expected snow load that structures must be designed to support. Ensuring that buildings can withstand this load is crucial for the safety and longevity of the construction in areas prone to severe winter weather. Understanding local snow loads is vital for contractors to comply with building codes and ensure the stability of their structures.

The other values may represent loads in different locations or conditions but do not accurately reflect the specific ground snow load requirement for Duluth, reinforcing the importance of local regulations and climatic factors in construction practices.
