Cannot Find Related Section Definition for Custom Member Verification

[umut.akparlar]

Hi,

I need to use double UC beam on top of each other and I simply mirrored / copied it to create the desired cross-section. I check the stress analysis, and it seems there is no issue with stress or load transfer between two UCs.

When I wanted to save this custom cross-section, I couldn't find the related shape for member verification.

Is it possible to code check a cross-section like this with RSA?

Thanks

Hi @umut.akparlar.

Seems is not possible. See the list of section and shapetype here:

Correct shapetype it´s necessary for Robot to do  steel design.

Thank you @CaioSaporito 

I modelled a similar cross-section with idea statica and when I check the beam, it only checks based on yield strength and shows the deflections of similar double I section. I can get those values from Robot too with 3D stress analysis option.

I understand we don't have an exact shape code check parameter in Robot for this case, but we can still select a similar shape in section definition to save it and check it manually based on equivalent stress and deflection, right?

Thanks

HI @umut.akparlar 

Yes, it is possible to approximate this welded section by comparing it to a similar neighboring shape to obtain an estimated result.
