Snow Drift Loads in U.S. and Canada – Similarities and Differences

Snow provisions in early editions of ASCE 7 were based mainly on Canadian practice. Currently although there are similarities, U.S. snow drift provisions differ in significant ways from Canadian provisions. The webinar will discuss these differences in relation to leeward roof step loads.

Attendees will get a review of current U.S. and Canadian approaches for snow drift loading, learn the influence of ground snow load, upwind fetch and winter wind upon U.S. leeward roof step drifts, and learn the influence of the characteristic length and the Cw factor upon Canadian leeward roof step drifts.

• Course will award 1.0 hour of continuing education
• Diamond Review approved in all 50 states
• This webinar will be available as a recording.

Please note: This webinar is part of the NCSEA Webinar Subscription.
