wires.
http://www.seismicceilings.com/ USG Seismic ceiling resource center lists
code requirements in the CISCA guide and has .pdf and .dwg details.

You are correct. CISCA references the splay wire and compression strut in
"Guidelines for Direct Hung Ceiling Assemblies in Seismic Zones 3 & 4".
There were some studies a while back that indicated that the lateral drift
was too great to reduce damage if splay wires were used without compression
struts.

I believe the compression posts come from ASCE's reference to "CISCA for
Zones 3 & 4" for installations in D-F buildings. I don't have a copy of that
to verify current requirements.

Does the CBC 2007 (IBC2006) still require seismic compression struts for
suspended ceilings? I cannot find it in the code?
Thanks
