From the table, the snow load increases at a rate of 7 psf. A contour map has been created from which the ground snow load can be determined at any location in Montana. In the State of California, no statewide maps exist that include local jurisdiction snow load values. 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 … 10183 Truckee Airport Road Truckee, CA 96161 .

Experience has shown that there are very large local variations in snow load in mountainous regions. Local and/or state requirements on the ground snow loads or roof loads supercede the values provided by this tool. You can click on the map below to find the design ground snow load for that location. Local knowledge should be obtained … Engineering judgement must be exercised where the predicted elevation greatly differs from the actual elevation at the site. Frost Depth. The latitude and longitude of the site may be entered on the top line. Tabled values for Infrequent, irregular, short duration snowfalls and single isolated very heavy snowfalls need to be taken into account when determining the characteristic values of ground snow loads for use in structural design.

Snow loads acting on a sloping surface shall be assumed to act on the horizontal projection of that surface. Letherer Truss, Inc. - Established in 1989, our company is family owned and operated. The snow load values displayed by the online map and returned by the lookup tool are 50-year mean recurrence interval (MRI) ground snow loads. The 50-year ground snow loads to be used in structural design are presented in two formats. Keep in mind any elevations above 1,000 feet, the ground snow load shall be increased from the mapped value by 2 psf for every 100 feet above 1,000 feet. 64 psf. Use our Montana Ground Snow Loads map to easily determine the ground snow load (Administrative Rules of Montana: 24.301.146) for any location in the State of Montana.

Comprehensive Plan - … The European Ground Snow Load Map Many clauses of EN 1991-1-3 are based on the results of a research work, carried out between 1996 and 1999, under a contract specific to this Eurocode, to DGIII/D3 of the European Commission. Inspectors are in the office between 8am and … Use only within immediate vicinity of given town, particularly if ground elevation changes noticeably. In those areas the national map contains the designation “CS” instead of a value. CS indicates that case studies are required to establish ground snow loads in these areas. For sites in these states, users are directed to individual state tables with elevation and ground snow load for … For example, if the lookup tool returns a ground snow load value of 160 psf. The "snow load" is a measurement of the weight of the heaviest snow load likely to occur in a two-month period in a certain region. ASCE 7-16 presents ground snow load information as a map and as tables for selected states. Local and/or state requirements on the ground snow loads or roof loads supercede the values provided by this tool. A European research group was formed to produce a unified snow map for Europe. psf (pounds per square foot) ABOVE LINE 60 PSF . Your browser doesn't seem to have a PDF viewer, please download the PDF to view this item. Site specific case studies are required in these areas. Loads are in pounds per square foot. In other areas the values presented on the map only apply up to certain elevations, which are shown in parentheses. The information reflects the ASCE maps electronically to speed up critical design project information and displays easily for your convenience.
