How do I create an imperfection based on a mode shape in RFEM 6?

Answer

To create an imperfection based on a mode shape, the Structure Stability Add-on is required. In this way, mode shapes can be determined for a load case or a load combination based on its axial force state. The resulting mode shape can be selected and scaled after creating an imperfection case. The video shows the procedure.
