Snow Loads in ASCE 7-22 , What’s New and Different

Stay up-to-date with critical changes in snow load design with this informative webinar, tailored for structural engineers, architects, and building code professionals. We’ll begin by unpacking three major updates in ASCE 7-22: the new ground snow loads, the addition of a winter wind parameter for drift loads, and significant revisions to the shape of windward drifts.

We’ll then dive into two frequently asked topics: the influence of roof R-value on the new Ct thermal factor, and the criteria for determining the height of parapet walls that fully capture drifting snow. Finally, we’ll explore new provisions for superimposing drifts from two different wind directions.
