I have used STAAD design parameters related to section 12 of IS800-2007 LSD. It has been found that major bracings are having same stress ratio. Unable to track the reason. Anyone have any suggestions, references?
This is a reporting issue when chapter 12 in considered in design for non-tapered section. A BUG 977465 has already been logged and being worked upon. It will be fixed in next release. The check we do for strength capacities using chapter 12 conditions will be done but will not be a part of utilization ratio report as that gives a wrong impression.
