Question
Is it possible to design a restrained column base with stiffeners on both sides of the column in an RFEM/RSTAB add-on module?Answer
Yes, a restrained column base with lateral stiffeners can be designed with the RF-/JOINTS Steel - Column Base add-on module.
The joint category and joint type must be selected in Window "1.1 General Data", see Figure.

General method for stability designs according to EN 1993-1-1 and buckling in the main bearing plane
In EN 1993-1-1, the General Method was introduced as a design format for stability designs, which can be used for planar systems with any boundary conditions and variable structural height.

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.
