design a rotate steel section

[carlito_elle]

It's possible to verify a rotate section like shown in the picture attached? 

Look at the up and lower HEA100. Thanks.

Yes, just assign the correct member design parameters on Design/Stell member design-options/Code parameters...

Thanks. I tried it, but still having same instability. Could you check and helpme? is just 1 simple truss. thanks, attached the file.

I'm ok with the instability check for the upper and lower beam if Im doing settings like in the picture? I would like to use the automatic design check. Or I need to do another file with 1 piece for the upper and lower beam?

Thanks

Hi @carlito_elle 

I used these bucklinh parameters, but still ratio > 1

Keep in mind that lateral buckling is not available for this kind of configuration
