As I understand it, a flexible superstructure on a much more rigid sbustructure will not be significantly influenced by the dynamic properties of the substructure. Thus, these provisions allow a more refined analysis than using the the lower R-value for the entire structure. -----Original Message----- From: Jeff Creagan [mailto:jeffc(--nospam--at)kpff.com] Sent: Friday, October 01, 1999 2:01 PM To: seaint(--nospam--at)seaint.org Subject: Two-Stage Analysis Does anyone know the background behind the two-stage design procedure requirements in UBC 1630.4.2 and 1629.8.3, Item 4? This provision was first introduced in the 1988 UBC but I can find no commentary that indicates the basis for it.
