Display Settings RFEM RSTAB

In RSTAB/RFEM, I have defined a tapered member consisting of two different cross-sections. In the rendering mode, it is displayed incorrectly. What did I do wrong?

Answer

If there are different cross-section types with a different number of stress points at the beginning and end of a cross-section, RSTAB/RFEM models the two halves with the two different cross-sections, respectively.

A "continuous" taper is drawn if both member ends have the same cross-section type (cross-section row).

Therefore, you can replace the cross-section with the smaller depth by a cross-section from the same cross-section row as the cross-section with the greater depth (and, if necessary, adjust the depth for special cross-sections).

Tip:

The easiest way to do is when you model both cross-sections as welded sections.
