Take a Load Off: Understanding Rain and Snow Loads on Pre-Fabricated Steel Buildings

Take a Load Off: Understanding Rain and Snow Loads on Pre-Fabricated Steel Buildings

Are you considering purchasing a pre-engineered, pre-fabricated building If so, an awareness of the precipitation load is crucial for the team of engineers and designers working on your design. Especially if you are looking into building in the northern regions of the U.S.

Your team of experts need to determine the following factors concerning rain and snow loads:

  • Structural integrity
  • Weight capacity of the roof.
  • Water run-off systems
  • Balancing the structure.
  • During the early planning stages, these components weigh heavily into the designing and manufacturing of your steel building.

    The accumulation of ice, snow and rain your building becomes exposed to is called Design Snow Load. Precise calculations are generated too help ensure your building will withstand the elements.

    Snow acts like a sponge. If you are building in an area known for high precipitation, the team needs to know this beforehand.

    The formula is figured by calculating the amount of ground snow typical for the region; if there is three feet of snow on the ground, there will be three feet of snow or better, on the roof.

    While discussing your design, bear in the mind that wind, and milder temperatures melt snow. This is referred to as Partial Snow Load. Run-offs and gutters need proper placement to accommodate this load. Larger pitched roofs that snow can slide off of should not be abutted next to flat roofs without allowing for fortification of the structure and installing efficient run-off systems.

    Live Load refers to the weight of people and objects inside your building. Some walls and parapets may be subject to considerable amounts of stress. Accurate figuring in the planning and designing process is vital to producing a sound, safe building.

    Providing for the amount of unbalanced snow constitutes planning for both hipped and gabled specialty roofs within the pre-fabricated structure. Pitched roofs, and flat roofs are carefully placed enabling a them to handle the full amount of snow load.

    If the roof isn’t steep, or proper run-offs are not added, the building can become compromised. Careful calculations become crucial to achieve proper snow balance. Extra structural support and/or greater roof inclines are solutions to partial loading.

    The given operative life span of a steel building is aided by the proper placement of effective water roof drainage systems during construction.

    Thanks to the team of dedicated professionals working with these precise formulas, you can look forward to a stable, secure steel building. One that should last you a lifetime.
