Regards!
I would like to know how to define and design a composite column in robot structural. Is this possible? I need it to offset the lateral displacements caused by the seismic force.

Thank you very much! So the software can't design a composite column just can define it. Is this right?
Yes, as Mr. Atrur said:
"Such sections can be used in a model for static analysis, you can check stress distribution in the Stress Analysis module but the design (code checking) of such section is not supported in Robot. "

I did a simple test. I defined a composite column and I applied a 500 kg lateral load. So when i saw the lateral displacements they were the same. The composite column and the simple column had the same displacements. I need to counteract the lateral displacements with composite columns. How can I do that in the software?
Hi @Anonymous
First of all, sorry for my late respond,
I have made a simple test too, as shown in figure using:
Rectangular concrete column (0.30*0.60 m), IPN 450 section and a composite section of both of them.
Here you can see that Robot results perfectly matches my hand calculations:

Hi @Muhammed.OPERA.
Thank you for a nice walk throug and example.
I am trying to do something similar - however I am running in to some issues.
I am trying to model af circular steel section Ø650, t=12mm with concrete cast inside.
However I am running in to issues:
- The section geometry (pipe) is not showing up in the Robot static model. No geometry is showing.
- The section properties (which are calculated in the section editor) are not showing up the static robot model.
- Ix is not calculated for the combined section
So far I have only been able to do a section in the Robot Model be the use of typing in the values manually. Here I have used Ix for the steel section alone.
However I would very much like to be able to import the saved section from the database.
Would it be possible for you to explain the approach to this?
