Robot - 2D Steel element Design

[leegsstewart]

Good morning,

I am a new robot user and am undertaking a simplified 2D frame analysis as attached. The member as shown is a CHS and split by  node 5, creating bars 2 and 4. I wish do design this element for an axial buckling length forthe sum of bars 3 and 4, but cannot appear to be able to 'join' these as one.

Any tips would be great!

Thanks

Josef

Rafal,

Thanks for your quick response. I have tried to adjust members 3 and 4 to a super member but cannot locate the command?

Cheers
