Webinar on Demystifying Cold-Formed Steel Torsion Analysis for Design
$100.00
Continuing Education Credits Available – 1.5 PDH Credits
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

He is a member of the American Iron and Steel Institute (AISI) Committee on Specifications and chairs the AISI Committee on Member Design.

Coordinating CFS Framing with Metal Buildings Webinar
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?

Webinar on Post-Installed Anchor Testing, Qualification, and Design Procedure
Continuing Education Credits Available – 1.5 PDH Credits
Structural and non-structural elements are often connected to concrete structures by means of concrete anchors. Anchors are either cast-in the concrete during construction, or post-installed when the concrete has cured. There are various concrete anchor types with different behavioral characteristics. The designer must select the type, size and embedment most suitable for the given situation. Due to the large diversity in product types and makes, anchors are not standardized and products need to be qualified for their intended use. For this, suitability and serviceability tests on individual anchors are carried out in independent test laboratories. Evaluation of the test results ultimately result in the issuing of technical approvals which also provide the necessary data to carry out safe anchor design. In this webinar, the process for testing and qualification of post installed anchors, relevant building code and acceptance criteria will be discussed along with the design procedure, failure modes, and the factors affecting the failure mode.

Innovative Options with Cold-Formed Steel Floor Systems Webinar
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.
