Webinar on Design Aids for Cold-Formed Steel CFSEI Tech Notes

Continuing Education Credits Available – 1.5 PDH Credits

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.

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.

Curtain walls with various types of cladding are commonly used for many modern structures and are often framed with cold-formed steel. Curtain walls are typically attached to the main building frame and therefore must be designed to accommodate deflections of the structural frame and also designed to transfer wind and seismic forces to the structure. This webinar will cover many of the topics a designer will need for a complete cold-formed steel curtain wall design. The information presented will be based upon AISI S100, North American Specification for the Design of Cold-Formed Steel Structural Members, AISI S211, North American Standard for Cold-Formed Steel Framing – Wall Stud Design and various CFSEI Technical Notes. Some specific topics covered will include stud design, top track design, design of openings, bridging and various additional miscellaneous topics. Example calculations will also be provided covering studs, top track, connections and openings.

Presenter: Sutton Stephens, P.E., S.E., Ph.D.

Sutton Stephens, P.E., S.E., Ph.D. has experience in the structural engineering field and in education. He has worked for consulting engineering firms in Washington and Montana and taught structural engineering courses at Kansas State University in the Architectural Engineering Department. In addition to the design of cold-formed steel structures, he has authored or co-authored a number of research papers covering various topics in cold-formed steel. He has served in the AISI Committee on Framing Standards (COFS) and chaired the Prescriptive Methods sub-committee. He also served on the CFSEI Executive Committee for two terms.

For decades, Power- Actuated Fasteners (PAFs) have been used in the construction industry as a safe, reliable, and productive method to fasten various building components-such as cold-formed steel (CFS) framing-to steel and concrete. Code provisions for the use of PAFs in seismic areas for attachments of cold-formed metal framing to concrete have been subject to various interpretations. This presentation will provide recommendations based on Hilti’s understanding of the code provisions.

AISI S100-16, North American Specification for the Design of Cold-Formed Steel Structural Members, 2016 Edition (including the latest supplements), provides some basic provisions regarding calculation of the shear and tension resistance of a connection between CFS and concrete, but does not provide specific equations or values. In addition, Chapter 13 of ASCE/SEI 7-16, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, includes some restrictions regarding the use of PAFs in Seismic Design Categories (SDC) D, E, and F. Chapter 13 is entitled “Seismic Design Requirements for Nonstructural Components,” so the focus is on nonstructural applications like partition walls.

This presentation is designed to clarify the intent of the language in the code-referenced publications AISI S100 and ASCE/SEI 7-16 as it relates to PAFs used to attach track to concrete, in SDC A-C and SDC E-F. The presentation will also provide practical guidance to the designer regarding which design values should be used and where those values can be obtained. Additional practical recommendations will be provided regarding the specification of various types of PAFs and their embedment depths into the concrete.

Fire Resistance of Wall, Floor & Ceiling Systems

The presentation will begin with a review of the standards used to test both wall and floor/ceiling assemblies. Special attention will be given to factors that affect the design of systems with cold-formed steel, and some comparisons will be made to wood-framed systems. Several UL-certified fire designs will be described that showcase how structural factors can affect fire design.
