Slender Architectural Column 2

[StructuralAddict]

Hi,
I need to design an architectural column that supports only its own weight.
The column length is 9.0 meters and its diameter is 0.3 meters.
The KL/r > 100.
So, the ACI requires that Section 10.10.1 be used to compute forces and moments in the frame by performing second-order analysis.
My question is: do we need to perform the second-order analysis even if the column is supporting only its own weight?
Thank you!

For what it's worth, l/r=120 is almost identical to a round toothpick (discounting the tapered ends obviously)..

Where is the code reference for kl/r > 100?

I can find that limit in ACI 318-05 10.11.5 but cannot find it in later codes.

Help, please!

What is the problem of doing second order or nonlinear Analysis ???
