The webinar introducing AISI S250, North American Standard for Thermal Transmittance of Building Envelopes with Cold-Formed Steel Framing, will walk attendees through the history, development and contents of the AISI S250 standard. Participants will obtain a relative understanding of how to apply the various provisions in order to evaluate the thermal capabilities of envelope assemblies (e.g., walls, ceilings/roofs) containing cold-formed steel framing for use in professional practice. Jonathan Humble led the work group responsible for the development and publication of the AISI S250 standard.

He has received architectural awards for his designs while in the practice of architecture.

Jonathan was inducted into the American Institute of Architects (AIA) College of Fellows for his outstanding contributions to the AIA and its membership. He is a recipient of the International Code Council’s Honorary Membership, ASHRAE International’s Distinguished Service Award, National Fire Protection Association’s Committee Service Award, and the Cool Roof Ratings Council’s Marty Hastings Award, all in recognition of his exceptional service and contributions to these codes and standards organizations.

Jonathan’s activities within AISI include research and development of new technologies for AISI standards and guides, participation in national model codes and standards development, and educational services to steel industry members, design professionals, code officials, general contractors and building owners.

In order to receive credit for this course, you must complete the quiz at the end and pass with at least 80% for a certificate to be generated automatically.

Last year alone the CFSEI Hotline responded to over 4,800 inquires. These inquires cover the gamut of cold-formed steel applications. Because these questions often are beyond the scope of a design standard engineering judgement is needed.

Roger will review a few of the Hotline topics with a focus on employing engineering principals to solve everyday design considerations. Topics to be addressed are …

• Should loose straps be a concern?
• Does gypsum between the steel plies impact the screw connection strength?
• For the single-side strap brace, what are the implications for the design of the boundary post?
• How does one design a shear wall for force transfer around openings?
• What wind loading drift limits are appropriate for mid-rise structures?

 
Presenter: Roger LaBoube, Ph.D., P.E.
Wei-Wen Yu Center for Cold-Formed Steel Structures
 
Roger LaBoube, Ph.D., P.E. is Curator’s Distinguished Teaching Professor Emeritus of Civil, Architectural and Environmental Engineering and Director of the Wei-Wen Yu Center for Cold-Formed Steel Structures at the Missouri University of Science & Technology (formerly University of Missouri-Rolla). Dr. LaBoube holds B.S., M.S., and Ph.D. degrees in Civil Engineering from the University of Missouri-Rolla. Dr. LaBoube has an extensive background in the design and behavior of cold-formed steel structures. His research and design activities have touched on many facets of cold-formed steel construction including cold-formed steel beams, panels, trusses, headers, and wall studs as well as bolt, weld, and screw connections. He is active in several professional organizations and societies, including membership on the American Iron and Steel Institute’s Committee on Specifications for the Design of Cold-Formed Steel Structural Members and chairman of the AISI Committee on Framing Standards. He is a registered Professional Engineer in Missouri.

Cold-formed steel (CFS) framed floor systems used to be simple and straightforward: joists at 16” or 24” on center aligned over wall studs with the joists braced with blocking/strapping every few feet, all topped with plywood or pan deck and concrete.  But now the rules have changed.  With the advent of ledger framing and load distribution members and composite CFS floor systems, we are seeing true innovation in floor framing, as well as how floors are built/supported/topped. With new products being developed at a rapid pace, engineers have to keep up with the latest to select economical and lightweight systems that can now compete with the efficiencies of open-web bar joist and composite deck systems.  This session will provide an overview of several CFS floor framing systems and methodologies that are starting to win back floor framing from other materials, and other potential efficiencies that can be gained from the inherent versatility and constructability of CFS floor framing.

After attending this presentation, participants will be able to:

1. Design and detail joist and truss support systems that obviate alignment framing and provide more flexibility for field fixes and bearing wall openings.
2. Evaluate a wide variety floor topping materials that provide joist bracing, diaphragm strength, and gravity load support.
3. Consider options with wider spaced joists or trusses: using the span capabilities of steel deck or steel-and-concrete systems.
4. Consider composite design with CFS and concrete systems: both deck and joists and combinations of these.
5. Know where to go for additional resources on floor issues.

The North American Standard for Cold-Formed Steel Framing – Nonstructural Members, AISI S220, has been adopted into IBC 2015. AISI S220 was created to help delineate and eliminate the confusion between the engineering principles and requirements for cold-formed steel structural members and nonstructural members. The webinar will address the basic behavior of composite vs non-composite wall assemblies, as well as design requirements that differ between the structural and nonstructural member.
