UG-29 - Stiffening ring - lateral buckling
UG-29 - Stiffening ring - lateral buckling
(OP)
Hi,
In BPVC Section VIII, Div-1, Subsection UG 29 on stiffening ring, there is a paragraph that says "CAUTION: Stiffening rings may be subject to lateral buckling. This should be considered in addition to the requirements for Is and I's [see U-2(g)]". How is lateral buckling generally analyzed for stiffening ring or not analyzed based on certain engineering judgment?
Thanks,
Monk

Please, can you tell us the literature?

FYI, after some more digging, check out page 11 of this literature that I found online that provides a width to depth ratio of the ring section based on the Young's modulus and yield of material.

The equation used in the above literature is based on theory of compact vs non compact sections. Here is a link for brief explanation: http://www.wikiengineer.com/Structural/SteelBeamCo...
ASME BPVC 2286 Figure 1.4.4. has the same information as guide for width to depth ratio. That case number has a lot of information and I am still slowly trying to digest everything.
