CFS frame lateral force resisting systems code requirements were
first introduced into the 1997 UBC and served as the basis for their inclusion
into the AISI Lateral Design standards, AISI S213. There are now several good
references and tools to help in the design of these systems. While somewhat
similar to wood framed design, there are some differences for which
understanding is necessary to ensure proper compliance and performance of these
systems. Many of the questions regarding cold-formed steel frame seismic
force-resisting systems regard the various system choices, which floor framing
system should be used, overturning restraint options, wall stud bracing design,
the use of the overstrength factor, Ωo, and anchorage of the overturning
restraint system to concrete. This presentation will discuss these aspects of
design and include various examples including from the CFSEI Shear Wall Design
Guide.
