In addition to the National Annexes (NA) listed above, you can also define a specific NA, applying user-defined limit values and parameters.

Automatic calculation of all required factors for the design value of the flexural buckling resistance N_b,Rd
Automatic determination of the ideal elastic critical moment M_cr for each member or set of members on every x-location according to the Eigenvalue Method or by comparing moment diagrams. You only have to define the lateral intermediate supports.
Design of tapered members, unsymmetric sections or sets of members according to the General Method as described in EN 1993-1-1, Cl. 6.3.4
In the case of the General Method according to Cl. 6.3.4, optional application of 'European lateral-torsional buckling curve' according to Naumes, Strohmann, Ungermann, Sedlacek (Stahlbau 77 (2008), p. 748‑761)
Rotational restraints can be taken into account (trapezoidal sheeting and purlins)
Optional consideration of shear panels (trapezoidal sheeting and bracing)
Module extension RF-/STEEL Warping Torsion (the licence is required) for stability analysis according to the second‑order theory as stress analysis, including consideration of 7th degree of freedom (warping)
Module extension RF-/STEEL Plasticity (the licence is required) for plastic analysis of cross‑sections according to Partial Internal Forces Method (PIFM) and Simplex Method for general cross‑sections (in connection with the RF‑/STEEL Warping Torsion module extension, it is possible to perform the plastic design according to the second‑order analysis)
ULS design: Selection of fundamental or accidental design situations for each load case, load combination, or result combination
SLS design: Selection of characteristic, frequent, or quasi-permanent design situations for each load case, load combination, or result combination
Tension analysis with definable net cross-section areas for member start and end
Weld designs of welded cross-sections
Optional calculation of warp spring for nodal support on sets of members
