Presentation Outline: Cold-formed steel columns and joists with open cross-sections can be susceptible to distortional buckling. Learn what causes distortional buckling and how to minimize its effects in practice. Design examples employing AISI-S100-07 were provided.

PDHsThis Webinar includes:

  • How to identify distortional buckling and other failure modes.
  • Quantification of distortional buckling.
  • Where it occurs and how to avoid it.
  • Recent research.
  • Code requirements and provisions, including using sheathing as a restraint for distortional buckling in floors and walls.
  • Design examples.

Dr. Cris MoenDr. Cris Moen is an assistant professor in the Charles E. Via, Jr. Department of Civil and Environmental Engineering at Virginia Tech where his primary research and teaching area is cold-formed steel component and system behavior. He received his Ph.D. from Johns Hopkins University in 2008 and has several years of experience as a practicing structural engineer. He has performed research for the CFS industry on members with stiffened and unstiffened holes, and his research team has been selected to study energy dissipation for CFS members in conjuction with the AISI Seismic Design Opimization project. Cris is a registered professional engineer in Virginia.
