Design of special beams issues

Hi!

 

I would like to use a beam like the one in the attached picture. I have created the beam using the special beam section in Robot 2014. How can I evaluate this kind of beam?  I have tried the usual Steel design option but I keep getting the message: "Bars have not been calculated because they are composed of sections not available in the current code". Is there an easy way to evaluate the beam in Robot using a more theoreticly aproach in robot rathar than just Eurocode 1993?

As far as I know, no. 

For this king of section RSA takes into account only : reduction of internia, reduction of weight, but no local checking like for example Vieerendeel moment, needs of stiffeners etc .....

In the current version of Robot this kind of beams can be design according to the Polish code only.
