What is snow?

The burden of snow is a burden located on the ground or on the structure of snow, rime and ice that has accumulated. The snow load is usually calculated by means of equations that determine the amount of water present in the type and depth of snow accumulation. The ground snow loads are calculated first on the basis of the average sample of flat soil and the load transmitted by the roofs is usually derived from this figure. Building regulations require that the structures be able to conveniently support the most difficult snow burden that can be adequately expected to accumulate in the geographical area where they are located.

The snow tends to accumulate on the ground and on the structures in the cold climate during the winter. The accumulation of snow is often measured in terms of depth. This can provide a gross idea of ​​the actual weight of the presence of snow, but the actual weight of snow is very different, while the light powder the snow weighs very little and dense, wet snow weighs a lot. Calculation of snow load is based on weighing water in the snow in a given area rather than inthe depth of snow.

The weight of the water in a particular snow package can be determined by measuring the depth of snow and then applying formulas based on the composition of the snow package. These formulas are based on experimental evidence collected for many years and are quite accurate. This calculation method is preferred because in fact the melting and weighing of the representative sample of the snow package is a difficult process.

earth snow loads concerns the weight of water per square foot, which is developed on the ground by a snow package. These statistics are often not directly relevant, although heavy snow can damage some landscape features. Roof snow loads are much more important statistics and are calculated from the ground load in the area.

The load located on a specific roof is influenced by the design of the building and other -through initistemental factors. Folded roofs, especially steep roofs such as A-Ramy styles commonIn very snowy climates, they have very effectively shed snow and carry much lower load than surface structures. Melting can also reduce or redistribute the weight of snow on the roof.

Building codes make sure that the structures are able to withstand the largest snow burden that is likely to accumulate. The code requirements are therefore very different from the region to the region. It is not expected that houses in Florida will have a snow burden at all, while houses in areas experiencing large snow, such as Alaska or Rocky Mountains in California, may be obliged to carry more than £ 300 per square foot (61 kg per square meter).
