RE: SIPS in Seismic Design Category D, E ,F

For what it's worth, I do a lot of work with supermarkets and other such
buildings in SoCal. Most have large walk-in coolers and freezers, (which is
sort of where the SIP technology came from). We routinely see the addition
of steel frames to brace the panels almost without exception in short
direction assemblies. So somebody is calcing these things and they are
getting constructed and passed NOW, with some lateral resistance ratings
that some engineer somewhere is relying on and some building department
somewhere is accepting...

You might want to call some cooler box manufacturers and see if you can
contact their engineers to discuss it with them.

Short answer, no.

Longer answer, depends on what you define as acceptance. To my knowledge,
there are no SIP manufacturers that have an ICC-ES Evaluation report that
evaluates SIPs for use in SDC D, E, or F per the 2006 IBC. This is because
the ICC-ES has _NO_ Acceptance Criteria for evaluating SIPs for use in SDC
D, E, or F per the IBC 2006. They did approve an Appendix A for AC 04 a
couple of years ago that would have allowed an evaluation method for SIPs
as shearwalls in SDC D, E, and F, but the withdrew it about a year or so
ago. As a result, the only evaluation reports that I know of for "high
seismic" areas are legacy reports that evaluated under the 1997 UBC and
maybe the 2000 IBC.
