  • RFEM 6. Imperfection case based in a buckling mode.

    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.

    Hello, usually you will use this option:

    Imperfection

    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.

        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.

          Imperfection Case
          Imperfection Case

          I select the IC 1 in the CO 1.

          Load Combination

          The CO 1 appears in the list.

          Imperfection Case

            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.
