Back-to-Basics: Structural vs Nonstructural Members Webinar

Continuing Education Credits Available – 1.5 PDH Credits

This webinar will cover the basic design of cold-formed steel light frame diaphragms as envisioned in the provisions articulated in AISI S100-16, North American Specification for the Design of Cold-Formed Steel Structural Members, 2016 Edition; AISI S230-19, North American Standard for Cold-Formed Steel Framing―Prescriptive Method for One- and Two-Family Dwellings, 2019 Edition; AISI S400-15 w/S1-16, North American Standard for Seismic Design of Cold-Formed Steel Structural Systems, 2015 Edition with Supplement 1; and AISI S240-15, North American Standard for Cold-Formed Steel Structural Framing, 2015 Edition. Design practice documents derived from these AISI Standards will also be addressed. At the conclusion of this webinar, design professionals will have a better understanding of current provisions that support engineered design (strength and deflection) of conventional codebased light frame cold-formed steel diaphragms as well as the limitations of these provisions.

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:

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

A thin compression element of a cold-formed steel member – such as a flange or a web — may buckle before it reaches its yield stress. Thus, cold-formed steel design involves estimating the influence such buckling has on the strength of a beam or column.

What are these buckling conditions? How do they differ in their behavior? This webinar will explore the basic buckling behaviors encountered as one designs a cold-formed steel beam or column. Emphasis will be placed on the fundamental behavior and highlight the design expressions that enable an engineer to estimate buckling strength.

Join Roger LaBoube, Ph.D., P.E., on this journey through the wonderful world of buckling.

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.
