Sorry to let this one pass me by but I have been spending last week with my son (Jeeping around the desert) and working on deadlines. Bill, most of the ICBO reports issued will be for proprietary cold-formed sections such as those created by Angeles Metal products. I might be wrong, but since this is not a system intended solely for shearwalls, it would not likely have an ICBO issued for this purpose. The cold-formed shear wall system was done in accordance with the work done by Light Gauge Steel Engineer Association (LGSEA), NAHB, AF&PA, Canadian Wood Council and AISI. The latest work that was accepted in the '97 code originated with the test work done by Professor Surrette at Santa Clara University (I writing from memory and may have the wrong college listed). You can contact Larry Williams who is the executive director of LGSEA at lgsea(--nospam--at)aol.com. The report differs from the work done by APA which was representative of the older '91 or '94 UBC (see APA Research Report 153 and 157). The main difference was that Surrette's work reduced the thickness of the studs to 20 gauge in the panels to eliminate the possible shearing of the screws caused by 14 and 16 gauge studs in the past. The '97 UBC covers the design methodology based upon cyclic and monotonic criteria. We are finalizing the design problem in the SEAOC Design Manual as of this time. Bill, I indicated a bunch of facts above from memory. If anyone on the lists finds these to be incorrect, will you please let Bill know. My apologies in advance to anyone who I might have missed or incorrectly associated to this issue. Regards Dennis PS: If you wish to look at proprietary products which use either cold-form or rolled steel, check out the Hardy Frame from Hardy Industries. I've used these on two projects now and like them very much. I'd be willing to discuss this on the list with anyone else interested. Please indicated a new topic in the subject line - say, "Hardy Frame" The work was done together with -----Original Message----- From: Williston L. Warren, IV - S.E.

Also considering alternates to shearwalls, i.e., X bracing, anyone have a manufacture with guidance or by chance eval. Service information. Thanks, here is your chance Dennis Williston "Bill" L.
