An Explanation of Rain, Rain-On-Snow, and Snow Loads in Regards to Steel Structures

Wednesday, February 28th, 2007

All-steel building projects are detailed undertakings that require more than just design expertise, but consideration of local area climate conditions. This is crucial in localities that get loads of snow and rain.  Design Snow Load is a number that portrays the maximum probable weight of snow that can be present on a roof at a given time. The expression of live load is very dependent on building and building occupancy, but snow load correlates specifically to location on the building. Eventual design snow loads are extensively impacted by the ground snow amounts throughout a given area. There are select computations applied a supplied ground snow total quantity to a given building to actualize its proper design snow load. Any ground snow load number and also the flat roof snow load along with the exposure and thermal figures are added to any computations. Changeable roof steepness is then added in.
