The Applied Technology Council (ATC), with assistance from Metal Building Manufacturers Association (MBMA), has developed a website that provides a way for users to easily obtain an ASCE 7 site-specific ground snow load. A site can be selected by directly entering the GPS coordinates or the mailing address into the input window of the website. If needed, a map of the United States can be used to find the GPS coordinates of a particular site.

This website overcomes the challenges in using the snow load map that is printed in ASCE 7, Minimum Design Loads for Buildings and Other Structures. These challenges include insufficient spatial resolution of the map to determine some site-specific ground snow loads and the lack of reference cities or towns on the map.

On the ATC Ground Snow Loads website, users can obtain loads from the ground snow load map printed in ASCE 7-95 through ASCE 7-10 (1995, 1998, 2002, 2005, and 2010). Ground snow load is used with the equations provided in ASCE 7 to determine design snow loads for buildings and other structures.

The ground snow load site is now available for use free of charge at snowload.atcouncil.org. The site also provides a link to the windspeed website where ASCE 7 site-specific wind speeds can be obtained. Users are encouraged to provide ATC with feedback so that enhancements can be planned.

The Applied Technology Council (ATC) is a nonprofit, tax-exempt corporation established in 1973 through the efforts of the Structural Engineers Association of California. ATC's mission is to develop and promote state-of-the-art, user-friendly engineering resources and applications for use in mitigating the effects of natural and other hazards on the built environment. ATC also identifies and encourages needed research and develops consensus opinions on structural engineering issues in a nonproprietary format. ATC thereby fulfills a unique role in funded information transfer. The ATC website and online bookstore is located at www.ATCouncil.org. For more information about the ATC Ground Snow Load website, contact ATC via phone at (650) 595-1542 or This email address is being protected from spambots. You need JavaScript enabled to view it..

Founded in 1956, the Metal Building Manufacturers Association (MBMA) serves manufacturers and suppliers as it works to promote the metal building systems industry. Its membership represents more than $2.4 billion in annual sales and accounts for approximately 52% of the total non-residential low-rise construction market in the United States. The association provides a wealth of technical information on its website, www.mbma.com, for anyone who works with or is interested in metal building systems, and publishes numerous technical manuals and design guides.

What's New?


What's New? The ATC Hazards by Location website allows the user to find site-specific basic wind speeds, ground snow loads, tornado design wind loads, and seismic loads used in the standards published by the American Society of Civil Engineers, National Earthquake Hazards Reduction Program, and International Building Code. This website was developed with the financial help of the ATC Endowment Fund, Federal Emergency Management Agency (FEMA), Insurance Institute for Business & Home Safety (IBHS), and Metal Building Manufacturers Association (MBMA), and is free of charge to users.

Available Products. The library of completed ATC products includes more than 100 publications on key issues in structural, earthquake, wind, and coastal engineering.  Some are available as free downloads and others can be purchased through ATC’s newly updated online store.   More…

Projects. With funding from various government agencies and the ATC Endowment Fund, ATC is actively engaged in a broad range of funded technical projects to mitigate the effects of natural and other hazards on the built environment.

Events. Periodically ATC conducts seminars, conferences, workshops, webinars, and other meetings to document and advance the state of structural engineering practice and to identify research needs.  Registration for these events can be made through the “Events” section of this website.  ATC also has the ability to provide an instructor to conduct your ATC-20 and ATC-45 in-person trainings, and information about these options is available under On Demand Training in the Product menu above.
