Modeling of Tapered Member

In RFEM/RSTAB, I have defined a tapered member consisting of two different cross-sections. This is now displayed incorrectly in the rendering (see the "Incorrect Taper" graphic). What did I do wrong?


Answer:
If there are different cross-section types at the member start and end of a tapered member that do not have the same number of stress points, RFEM/RSTAB draws the first half with one cross-section and the second half with the other cross-section.
Furthermore, it is necessary to ensure that the stress points with the same numbers are opposite each other.

A "continuous" taper is drawn if the same cross-section type (cross-section row) is present at both ends and the stress points are opposite each other.

For example, you could copy the cross-section with the smaller height and then adjust the height and/or width of the second cross-section.

Note
The easiest way to do this is to model both cross-sections as welded sections or parameterized cross-sections.
