Automatic Interaction diagrams for a defined section

SOFiSTiK

Hello.
Happy new year to everyone.
I have a question. Does SofistiK allow an automatic display of normal force/moment interaction diagrams? I did some research but I couldn’t find any information about this.
Example. I want to design a pile of a bridge subjected to normal force and bending moment
I want to display the normal force/moment interaction diagram for this pile section with the defined RFT
Does Sofistik give this option? I usually use other programs to do it while taking the maximum reactions from Sofistik.

In the program AQB use the command CAPA.

There should be a teddy example if I remember correctly:
→ Open teddy
→ button examples
→ AQB in the folder tree

Yes, In this example in AQB folder
I don’t understand what is the value of My. Is this value the applied moment
and Why not appear in the interaction diagram the point of the applied straining action

In the example the interaction curves for normal force and moment are evaluated (TASK "NM") with the following examples:

  • N-My: My = 100 and implicitly Mz = 0 → check N vs My
  • N-My-Mz: My = 200 and Mz = 100 → check N vs My/Mz (My=2*Mz)
  • N-My-Mz: My = 100 and Mz = 100 → check N vs My/Mz (My=Mz)
  • N-ky-kz: My=Mz but using a factor instead of kNm

Basically you are just instructing whether you are checking uniaxial or biaxial bending.
