Hi

I am currently performing steel design.

My steel columns (18to21) sections have dimensions 100x100x8 and steel beams (22to23) have section 80x80x6,3.

Why do I get the following warning regarding wall thickness when none of my sections are that thin?

What's the reason for the elastic warning? (if I turn it of, I don't get the warning) 



In addition, my steel sections will be protected with fire coating/paint. Do I have to define a new material or can I use a existing one (if so, which one)?

Thanks in advance

Regards 

Peder

Could you send the model (you can leave only the part with these bars) please?

My assumption is that you used the option described here:

I'm afraid this is going to be your decision. I'm not in the position to tell you what parameters you should decide on.

thanks Arthur

I cant seem to be able to compress the file enough this time, even without results

Please refer to the followin thread which has the same model: http://forums.autodesk.com/t5/Autodesk-Robot-Structural/Structure-verification/td-p/3334637 -  Ole Deviks vei 6.zip 246 KB

I don't get any similar warning running the file you indicated.
