Hi,
1. I wish to know if "geomTransf PDelta" or "geomTransf Corotational" can consider the "Large P-Delta" effect, or it can consider just "small P-delta" in element.
2. If they can't, which procedure is proposed in general?
3. And At the end, what 's the original reference (which paper or book) for "leaning column" procedure?
Best Regards,
Horr

Re: large p-delta
None of the geometric transformations considers small P-delta. PDelta is actually "Large P-Delta".
Here is a reference for leaning column:
