Moment magnification in columns (error?)
Moment magnification in columns (error?)
(OP)
Hi everybody, I´m a rookie in Etabs. I have been cheking some columns with the following results.

The column is slender, and per ACI 10.10.6.5 the minimum bending moment should be "M2min= Pu*(15+0.03h)" which is ok in Etabs.
My question is, the design moment Mu2 (-0.4kNm) should be the minimum bending moment (12.55 kNm)? Etabs design the column with Mu2(-0.4kNm) and Mu3(-16.68kNm).
Thanks in advance!
