Lateral Torsional Buckling
(OP)
When evaluating weak axis bending of a member of any shape, can Lateral Torsional Buckling occur?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Lateral Torsional Buckling
So from what I gather, when a beam is bent about its minor axis, it cannot deflect laterally (lateral torsional buckling) because Ix >> Iy such that it will just keep buckling about it’s minor axis until section capacity is reached.
On the other hand, bending about the major axis, because Iy << Ix there becomes a vulnerability such that the section will want to deflect outwards and thus initiating LTB before sectional capacity.

Normally, no. But, in certain cases it can. See this link:

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

KootK...check out the author of the AISC reply above. Just discussing him yesterday.
