Cold-Formed Steel Framing and Building Seismic Drift - What Happens to Our Framing When Buildings Move?

Earn 1 PDH / 1 LU

Buildings move in a seismic event, sometimes quite significantly. So, what happens to the cold-formed steel (CFS) non-load-bearing framing during a seismic event? What techniques are used to accommodate that movement? Do they work? Do they cause other problems? Do loads on CFS framing change depending on how the CFS framing accommodates the base building movement? Do discontinuities occur when movement-enabling connections and strategies are employed?

Come learn how a building’s seismic drift affects CFS framing and what strategies make sense, and what strategies may just cause more problems than they are worth.

Learning Objectives: 

  • Understand how buildings move under different loading conditions.
  • Understand the various ways that a building’s seismic drift affects CFS framing.
  • Understand the loading on CFS framing depending on the support mechanism.
  • Understand the discontinuities that occur when movement-enabling connections and strategies are employed.
