Hi,
what would be the easiest way to model steel pole with triangular cross section? 30/30/30cm at bottom and 10/10/10cm at top!
Regards!
Pole with triangular steel cross section
Is it a solid or a "tube" steel section??
If solid , you will have to divide the pole on smaller parts and create an average section for each divided part. You can use section definition module for it or on RC columm section type choose ...
...and change to the correct steel material.
If it is a tube section , you will probably will have to do the same . But maybe you can try on on steel type section / tapered tab , the polygonal tube section. It gets red if you choose less than 5 sides , but it still works . Didn´t check the results but maybe they are correct.You just have to figure out how to set the correct diameter to get the correct triangular section.
Maybe official support can say if this is really working or not.

Hi @Anonymous
The section type suggested by @Rafacascudo has not been intended for 3 sides so I can't tell as I never used it in this way and you 'd need to check the obtained results and see if it works for you. On the other hand what kind of results do you want to look at? If it is stress distribution yo may consider modelling it as a shell with panels instead.

Hi @Anonymous
It seems that for some reason the nature of load cases 'lost' their 'links' with the selected code combination regulation and it was needed to restore them. The video below shows the steps as well as the way of defining buckling analysis for all combinations at the same time.
I'm attaching the modified model as well.

Thank you @Artur.Kosakowski
One more thing that's bothering me. Why do I not see buckling lengths in your model?
Hi @Anonymous
Because I divided the bars into smaller calculation elements for larger accuracy of the calculations. Knowing the critical coefficient you can get the buckling length for the Euler formula but IMHO it is nit needed as you already know the critical load level.
