First Steps with RFEM
Description
In RFEM and RSTAB, it is possible to analyze members with a variable cross-section, which can also consist of freely defined SHAPE‑THIN cross-sections. For the determination of internal forces and deformations, the cross-section properties are interpolated.

Creating Member with Variable SHAPE-THIN Cross-Section
In RFEM and RSTAB, it is possible to analyze members with a variable cross-section, which can also consist of freely defined SHAPE‑THIN cross-sections. For the determination of internal forces and deformations, the cross-section properties are interpolated.
SHAPE-THIN | Cold-Formed Sections
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.
