Linking beams with different cross-sections

[Anonymous]

Hi all,

I'm quite new to Robot Structural and have been unable to solve the following problem.

How to link beams with different cross-sections?

Explanation:

- Both beams have identical outer dimensions;

- One section is fully concrete;

- Other section has an inside section of other material (surrounded by concrete);

I'm trying to link these sections into one integral beam, but haven't been able to do it so far. I've tried the Object Combinations function but doesn't seem to work for this task (unless I'm doing something incorrectly).

This is my first post in Autodesk community, thanks for enabling my access to the forum!

Any advice is welcome.

Thanks!

I'm not sure, but maybe found the answer from the following thread:

I decided to test the suggestion of using Bars in modelling instead of Beam and seems to be working -- the BMD was generated for the whole assembly and looked reasonable. Seems, that there's no need for any type of combining in this instance.

Prior to that, I had been using Beams and volumetric objects trying to make a composite beam.

Please correct if the outcome is wrong (so that somebody new to the software wouldn't get a false idea).

Thanks!

If you want to design a building like structure then using bar elements rather than solids is the correct way.
