The latest information on shearwall testing for light gauge steel studs was done by Professor Reynaud Serrette of Santa Clara University. The report issued is titled "Shear Wall Values for Light Weight Steel Framing" Report #LGSRG-3-96. The test performed two static and one cyclic tests. The Cyclic testing was done in accordance with the guidelines established by a SEAOSC committee who complete the criteria over a year ago. The results of this test, I believe, were published in the 97 UBC and are much less restrictive than the results published by APA in their Report #154. The modes of failure were the same in both reports however, APA recorded failure by stud buckeling in 16 gauge material, while Professor Reynaud's tests used 20 gauge studs typically. The LGSEA (Light Gauge Steel Engineers Association) is the main group working toward the development of standards and can be contacted on the Web at www.lgsea.com and you can also contact the organization Managing Director Larry Williams at lgsea(--nospam--at)aol.com. The organization is located in Nashville at (615) 386 - 7139. When calling this number, you may be routed to the organization president Dean Peyton PE of Anderson-Peyton 31620 23rd Avenue, South, Suite 321, Federal Way, Washington 98003 (206) 941-9929. LGSEA publishes technical journals as well as a fairly comprehensive Detail library for about $85.00 (paper publication). I just received the detail library and found it to be usefull, however, in my area we combine plated wood truss roofs with steel stud walls - not considered typical in the detail library. They have two prescriptive design guides that are excellent. I just received these and will attempt in the next few months to create MathCad templates based on the design measures. The one book is "Prescriptive method for Residential Cold-Formed Steel Framing" Second Edition and the second is an excellent Commentary to the first book. Some of the members of LGSEA are on this list including Tom Harris SE and myself (as well as a few others I know I am missing). Membership is $100.00 per year and well worth it if you intend to stay on top of this growing technology. This is much work to be done with light gauge steel construction and I know LGSEA could use the help of volunteer committee members.
