Member with Variable SHAPE-THIN Cross-Section

In RFEM and RSTAB, you can analyze members with a variable cross-section, which can also consist of freely defined SHAPE-THIN cross-sections. The cross-section properties are interpolated in order to determine the internal forces and deformations.

Members with a variable SHAPE-THIN cross-section can also be designed if the following is considered during the modeling:

In SHAPE-THIN, create the start cross-section and save it after the calculation.
Create a copy of the cross-section, for example, by using "File → Save as ..."
Adjust the geometric parameters such as height or width to create the end cross-section. Nodes and elements may not be added or deleted!
Calculate the cross-section and save it.

Editing Member with Variable SHAPE-THIN Cross-Section

After importing the two cross-sections in RFEM or RSTAB, you can check whether the modeling is correct in the rendering: A design is possible with the STEEL or RF-/STEEL EC3 modules only if the cross-section change is displayed as a linear distribution.
