INSTRUCTOR: Michael O'Rourke, Ph.D., P.E., F.SEI, M.ASCE
Purpose and Background
The snow load provisions of ASCE 7 cover typical structures and roof geometries. As a result, there are roof geometries and load issues beyond the scope of ASCE 7. This webinar focuses on such issues where engineering judgment is needed. This seminar will provide practicing structural engineers with insight into snow load issues not covered by ASCE 7-10.
The webinar is divided into three sections. Eight Frequently Asked Questions are addressed in the first section. FAQ topics include drifting at RTU's, drifts on an end-wall awing, and mitigation of roof step drifts at an addition, among others. The second section presents observations on snow related structural collapse statistics. This section highlights issues which are particularly important in relation to structural performance. The third section is a Q/A session with the audience.
Primary Discussion Topics
- Eight FAQ's
- Forensic observations
- Audience Questions
Learning Outcomes
- Identify four potential solutions to roof snow drifts at a new addition
- Determine the required height of a full capture wall to preclude drift formation beyond the wall
- Determine the drift load atop a short awning
Webinar Benefits
- Gain in-depth understanding of the snow load hazard
- Learn appropriate snow loading considerations
- Learn which situations lead to structural performance problems
Intended Audience
This webinar is intended for both private and public sector structural engineers involved in the design, analysis and/or review of the building structures. It is specifically intended for seasoned structural engineers who are familiar with the snow load provisions in ASCE 7, but are frequently faced with roof geometries and load issues beyond the current scope of the provisions.
