First Steps with RFEM
Description
When optimizing cross -sections in the add -on modules, you can also select any defined cross -section favorites lists - in addition to the cross -sections from the same cross -section row as the original cross -section.

Improved Cross-Section Optimization
When optimizing cross -sections in the add -on modules, you can also select any defined cross -section favorites lists - in addition to the cross -sections from the same cross -section row as the original cross -section.
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.
