The statewide and Warren County maps show the snow load requirements. The revised map eliminates some of the small zones that were present and uses a different load-altitude relationship and set of zone bands to make it more appropriate for use in design. 9.1 Annex C: European Ground Snow Load Maps his Annex presents the European snow maps which are the result of scientific work carried out under contract to DGIII/D-3 of the European Commission, by a specifically formed research Group. Ground Snow Load. Roof Snow Load. The statistical basis for these values are consistent with the requirements of ASCE7, with a 2% probability of exceedance. Oregon requires a minimum roof snow load of 20 psf (pm in ASCE7*) for all roofs, plus a 5 psf rain-on-snow surcharge for many roof types, resulting in a 25 psf minimum roof design … This elevation is approximated using the methods outlined in the report and may differ from the actual elevation at that location, particularly in steep terrain or at hills or valleys.

Experience has shown that there are very large local variations in snow load in mountainous regions. In other locations, elevations over 9,000 ft are also considered less accurate due to the limited number of stations at these elevations, and sometimes produce overly-conservative values. If you want to obtain more exact results, you can also open the advanced mode to take into consideration other factors, including: Roof exposure. Normalized ground snow load maps are also available for most of Canada from the Atmospheric Environment Service (AES) in Downsview, Ontario.

Building Codes. Loads are in pounds per square foot. During the development of the Eurocodes, the snow loads given by the National Standards were reviewed. Ground Snow Load. The National Building Code of Canada instructs to treat the 1-in-50-year ground snow load as a characteristic value of the permissible snow load. (Ed.) For example, if the lookup tool returns a ground snow load value of 160 psf. Report and Interactive Map About Ground Snow Loads in Idaho. The “Get Ground Snow Load” button is then pressed for the snow load values. The upper limit, however, is not as easily determined. We have updated the report and map for the ground snow loads in Idaho. The IRC uses the ground snow load from the map shown, together with the appropriate tables from the IRC, to design the structure. The SEAU and the authors cannot accept responsibility for prediction errors or any consequences resulting therefrom. The revised map eliminates some of the small zones that were present and uses a different load-altitude relationship and set of zone bands to make it more appropriate for use in design. There are currently no local exceptions and the weighting and interpolation routine used for each climate zone (entire map) is the same however all of this can easily be customized by zone, elevation, or any other parameter that comes into play. When using Figure 1608.2 for sites at elevations above 1,000 feet (304 m), the ground snow load shall be increased from the mapped value by 2 psf (0.095 kN/m 2 ) for every 100 feet (30.48 m) above 1,000 feet (304 m).

Validation of the dataset, statistical analysis, and spatial mapping were externally reviewed by MetStat, Inc. The snow load that is applied to our structure is not the ground snow load, but in most cases, the flat roof snow load. 90 mph, 3 sec gust. Since values are extrapolated rather than interpolated, the estimated values for snow loads at elevations significantly higher than nearby stations sometimes lead to unreasonably high snow load estimates. CS indicates that case studies are required to establish ground snow loads in these areas.
