Do you think it is right to design it as a 150cmx150cm column and rod element?

Hello, I am designing a building with etabs. 150X150cm columns available. It has a floor height of 4 meters. Do you think I might be making a mistake by modeling these columns as rod elements?

I think that you might be making a mistake in considering the use of these columns in real life. Too small for ties, fire rating...

Really hope they're steel columns and not concrete....

Why yes, I do in fact have no idea what I'm talking about

150 cm NOT 150 mm!

1500 mm square columns for 4m height seems ok for me as concrete!

The rods element has me confused, might be worth a google video on etabs and modelling.

I am not an etabs guy but in my programs we would design the columns as frame/beam members

Friends, the columns consist of concrete filling inside a 70mm steel profile. So it's not just concrete columns. Concrete filled composite columns. The building is a tall building over 200 meters. (It won't actually be done.)

I'd just model it in ETABs as a column frame, you can even define it as a composite section directly. 1500x1500mm concrete column doesn't seem too outlandish for a 200 story building

Never used Etabs but I would assume a ROD element is a tension element!
