Non-slender Columns
Non-slender Columns
(OP)
Folks,
I just want confirmation that minimum eccentricity need not be considered for columns that are not slender and be designed only for the actual moments it sees.
The thing that is confusing is the use of the word "shall" in ACI 10.12.3.2 and conflicting information in the commentary where it seems to suggest the contrary.
I would appreciate a clarification.

RE: Non-slender Columns
If you account for cracking, creep, etc. and do a second order analysis of your column (including P-small delta), then you don't have to use the slender column provisions in ACI (except that you still need to assume a minimum e).
RE: Non-slender Columns
Since when is minimum eccentricity considered in the analysis? I have always used it in the design stage and checked it against the moment I obtained from the analysis stage. Also, minimum eccentricity is autonomos from P-Delta, or so I thought.

RE: Non-slender Columns
Yes, the minimum e is before you do the second order analysis.
