APRIL 17: Snow Loads in ASCE 7-22, What’s New and Different

Presenter:

Michael O’Rourke | Prof. Emeritus Civil Engineering | Rensselaer

• The new wind parameter W2. Snow drift size in ASCE 7-22 is now based upon W2, as well as the traditional upwind fetch and GSL parameters. This new parameter accounts for the fact that the potential for strong wind in winter varies significantly across the US. 

• Windward snow drifts. In ASCE 7-22, the rise-to-run for windward snow drifts has changed from the prior 1:4 to 1:8, based upon observations from Norway. 

• Changes resulting from user questions or comments, such as, “My project has additional roof insulation and I expect that the roof snow loads will now be larger, but the Ct value for my unvented roof isn’t a function of the roof R-value”, and “How tall should a parapet wall be to prevent snow from a new taller addition forming an unexpected-during-original-design snow drift atop the existing roof?”  

• New provisions in ASCE 7-22 for snow drifts at locations such as parapet wall corners, where winds from two different directions result in drift loads that overlap.

ABOUT THE PRESENTERS

Chad H. Vogt, PE

Principal, e2engineers

Chad has 25 years of experience providing consulting engineering services for private and public clients. He merged his independent structural engineering firm with e2 engineers in 2010, looking to offer his expert knowledge to a growing practice.

Chad strives to find cost-effective solutions for his clients, many of whom rely on him for on-call or expert witness services. As Principal, Chad works closely with each member of the e2 team to ensure a collaborative and creative problem-solving environment. 

Mark Gallagher, PE

Principal, Langan Engineering

Mark has 28 years of diversified engineering experience, including geotechnical investigations and site evaluations, foundation design, bulkhead design, excavation support, construction oversight, environmental assessments, sanitary sewer design, stormwater management, and roadway reconstruction.

He has worked on the geotechnical evaluations for projects throughout the Northeast, including several warehouses and retail centers, Hudson Yards, and the United Nations. He has also overseen geotechnical construction including micro-piles, piles, caissons, tie-backs, pile load tests, grouting, lime stabilization, retaining walls, and controlled fill placement. Throughout his career, he has directed Langan’s efforts on international projects including residential and commercial projects in the UAE, stadiums in Iraq and UAE, and motorways in Greece.

Lee Chrisman, PE

Senior Project Manager, Langan Engineering

Lee has more than 17 years of experience with civil and geotechnical engineering projects throughout New England, including schools, warehouses, arenas, and retail centers.

Mr. Chrisman’s wide-ranging experience spans due diligence services, geotechnical explorations, foundation design, temporary support of excavation design, retaining wall design, ground improvement, and analysis and reporting. 

Michael O'Rourke, Ph.D, PE

Prof. Emeritus, Civil Engineering, Rensselaer

Michael earned his B.S. in Civil Engineering from Illinois Institute of Technology and his M.S. and Ph.D from Northwestern University. During most of his 47 years on the faculty in civil engineering at Rensselaer Polytechnic Institute, he has been involved in snow load research sponsored by the U.S. Army Cold Regions Research and Engineering lab, the National Bureau of Standards, the National Science Foundation, and the Metal Building Manufacturers Association, among others.

This research has resulted in publication of thirty snow loading papers in refereed journals and a comparable number of conference proceedings papers. He is the author of six ASCE Press books and three ASCE Press E-books. Dr. O’Rourke has been a member of the ASCE 7 Snow and Rain Loads Committee since 1978 and served as chair from 1997 through 2017.
