For comparison: in Euler's formula, we calculate the critical force such that when the column is subjected to it, it buckles. As far as I understand, the yield strenght of the material doesn't really matter.
However, when facing eccentric load, secant formula is used and a maximum strain is calculated, instead of a critical force. Does it makes sense then to use yield strength as a maximum admissible strength?
Edit: also, when derivating the formula for the maximum strain, one already considers the compressible strain and the bending combined. Thus, when calculating the maximum strain, I don't need to further make any considerations about their interations, correct?
