Webinar on Cold-Formed Steel Attachment to Concrete in Seismic Zones

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.

Cold-formed steel structural members are commonly subjected to torsion. The torsional behavior of open cross-sections can be complex, involving both warping torsion and St. Venant torsion. Most structural engineering curriculums do not teach this combined torsion response, leaving many engineers with limited ability to properly design for torsion. To complicate matters, most structural analysis software does not fully capture the torsional behavior for cold-formed steel members.

This webinar will review some torsion fundamentals and explain torsion distribution using analogies to flexural behavior familiar to structural engineers. The similarity to flexure will be demonstrated using the CFS® software. The AISI design provisions for combined bending and torsion will be reviewed, and the application of these provisions will be evaluated with several design examples.

Presenter: Bob Glauz, P.E., MSCE

Bob Glauz is the author of the CFS® software used internationally for cold-formed steel design. He is a member of the American Iron and Steel Institute (AISI) Committee on Specifications and chairs the AISI Committee on Member Design. He is also a member of the ASCE/SEI Standards Committee on Stainless Steel Cold-Formed Sections, the Structural Stability Research Council (SSRC) and the SSRC Task Group on Stability of Steel Members. Bob has authored several technical articles on lateral-torsional, flexural-torsional, and distortional buckling of cold-formed steel members.

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.

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.

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