Description
This presentation initially took place at the 2020 Convention.
Wind design for roof systems is rather complicated, and with the latest version of ASCE 7, it has become that much more confusing. Different editions of building codes and, therefore, different versions of ASCE 7 are used in different parts of the country. The three versions that are currently in use are ASCE 7-05, 7-10, and 7-16. While each provides a method to determine the wind loads acting on a building, the specifics of each method vary. There are also groups (e.g., FM, NRCA) that provide methods to determine the wind loads acting on a roof. Once loads are determined, a roof system with a tested resistance greater than the loads is chosen for use. If it were only that simple!
The presentation will discuss the similarities and differences between the three versions of ASCE 7 and the roofing industry-developed methods to determine loads. The presenters will provide insights regarding the application of the traditional Factor of Safety in various design methods, as well as design enhancements for improved long-term performance. Lastly, the presentation will take a deep dive into the numerous listing services that provide wind-uplift-rated roof systems, such as FM, UL, and SPRI.
