RFEM 6. Imperfection case based in a buckling mode.

[Helena Goni]

When creating an imperfection case based in a buckling mode, why do we have to define the scaling direction? The bucking mode is already a deformation.


 

[Frank Faulstich]

Hello, usually you will use this option:



Then, the deformation figure will be scaled as it was in RFEM 5.

Scaling in only one specific direction is an additional option in RFEM 6.

Ok, thank you!

I don’t have this add-on in my RFEM 5 license.

If I were to use this option with 7GDL, what would be the procedure?

What I understand is the following:

1. Activate the add-ons Stability and 7GDL.
2. Stability analysis.
3. Imperfection case > Type “Bucking mode” > Source “Select Load Combination”

But there are a lot of load combinations and modes. I have seen a webinar but the explanation is only for a member and 1 load case.

And also, I don’t know how to apply this in a real case. And there is this window that I don’t know how it works.

Hello, this webinar, starting at minute 50, shows how to apply 7DOF analysis to slightly larger models.

This window shows in which LCs the IC 5 is used.

Example:

I have defined an IC.




I select the IC 1 in the CO 1.



The CO 1 appears in the list.

Thanks Frank,

I don’t know why I have the assignment different to yours. I’ll contact the Spanish support.

I’ve watched the webinar, thanks, it would be nice to have the a webinar with the next steps: assignment of imperfections and analysis. This is so new for me.

Hallo Helena, I will forward your wish to Andreas Hörold. He organizes the webinars.
