Webinar on Direct Stiffness-Strength for Sheathed Braced Design of CFS Structural Members – a Proposal to AISI S100
$100.00
Continuing Education Credits Available – 1.5 PDH Credits
This webinar will discuss an alternative design approach, namely the “Direct Stiffness-Strength method” (DSSM) for the incorporation of the bracing effect of sheathing in the design of sheathed cold-formed steel (CFS) structural members. The motivation for this research is compiled from the research gap in appendix 2 of the latest American Iron and Steel Institute standard, which stated “New guidelines and procedures are expected in near future” for the sheathing braced design of CFS structural members.
The new DSSM approach presented is based on full-scale test results and individual sheathing screw connection test results previously published in the research articles of the authors. The test parameters investigated are different sheathing board types (to account for the performance of each sheathing type) and different dimensions of the CFS structural member cross-sections (to account for the member slenderness). A new set of empirical expressions are formulated to predict the stiffness and strength of the individual sheathing screw connections. This webinar will also present a simple two-step DSSM design example.

Webinar on Practical Allyship – 5 Actions Anyone Can Do to Promote Inclusion at Work
Continuing Education Credits Available – 1.5 PDH Credits
Creating an inclusive work environment is not just the “right thing to do.” Inclusive behaviors are tied to higher levels of individual performance and firm profits; yet creating and working in an inclusive work environment often feels elusive, as evidenced by the fact that almost two-thirds of workers are disengaged at work.
In this interactive session, you will learn about the business case for inclusive work cultures and five simple actions anyone can take to create a more inclusive work environment for those they work with, regardless of current role or firm size. Applicable to everyone from new graduates to CEOs, these strategies have been shown to create a more inclusive work environment while requiring little time or budget to implement. When implemented consistently, these strategies create better work cultures for everyone and improve the retention of coworkers in traditionally marginalized gender, racial, and ethnic groups. You will leave this session empowered with specific actions you can immediately apply to engineer inclusion in your everyday interactions.

Webinar on Vibration Serviceability of Floors with Cold-Formed Steel Framing
Continuing Education Credits Available – 1.5 PDH Credits
Cold-formed steel (CFS) joists and trusses have high strength-to-weight ratios and good overall economy, so they are popular choices for floor framing members. As is the case with most types of floor systems, CFS floors are potentially susceptible to vibrations due to walking and other human activities. This webinar will raise awareness of the importance of vibration serviceability by describing two forensics projects with lively CFS floors. The literature contains several floor vibration evaluation methods that might be applicable to CFS floor. However, unlike other materials, there is not a widely accepted and practical vibration evaluation method for CFS floors. Potential evaluation methods will be discussed.

Webinar on Cold-Formed Steel Classroom: Design Topics Not in a Design Standard
Continuing Education Credits Available – 1.5 PDH Credits
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?
