What do the symbols mean in the graphical representation of the mode shapes of the RF-/DYNAM Pro add-on module?

Answer

The symbols in the RF-/DYNAM Pro graphic should indicate that these members have a local torsional rotation.

Since the members are related to the centroidal axis in the graphic, rotations cannot be detected otherwise. For this reason, we have selected the display with the short vertical line with the small end circles.

In the animation, you can see that these symbols rotate and thus represent the rotations.

Keywords

Torsion rotation Rotation 4 - Mode Shape Mode Shape No. 1
