Concrete column with Rigid Reinforcement

[length zero]

Yes you are right
It seems that is imposible to calculate Ix for compozite sections in Section Definition Module in Robot

Hope that a member of the technical support from Autodesk will give an answer. This problem exist since 19 version of Robot Millennium.

Thank you!

P.S. I will bump this thread so that it will remain on top until someone will give an official answer. Thanks for understanding.

I want to design a structure which has concrete columns with rigid reinforcement (an europrofile HEB300 for ex). I created the composite section in Section Definition but there's no Ix.
I used the created section in a 3D model, after the calculation the same problem appears...no Ix inertia moment (torsional inertia moment) for the column.
The same problem appears in RSA2011 version too.
I have attached some screenshots.

Thanks in advance!

You have to contact Autodesk support and ask your technical question if you want Autodesk technical support help you. It's very unlikely that they answer your question in the forum.

First of all, I don't have any contact address for Autodesk RSA support.
Isn't this forum the official one of Autodesk? If there is another one please tell me.

This forum is official. but it seems there are not many autodesk specialist to help users in RSA forum, if there is anyone at all. Revit forum is much better. There are many Autodesk specialists there to help you with your problems about Revit. But here only users help each other.. We are so lonely here...

The Robot user community isn't that well supported by autodesk. At least, if autodesk would give on the installation description a link to this web forum, the RSA users that would use this forum will increase, so that more experienced RSA users will share their knowledge.

P.S. Pap, can you answer please?

Hi, Torsional moments (Ix) are calculated for non-composite sections only, at present.
