Tips & Tricks
In addition to the stability designs according to EN 1993‑1‑1, Clause 6.3.1 to 6.3.3, you can also apply the General Method according to EN 1993‑1‑1, Clause 6.3.4 in RF‑/STEEL EC3.
This can be extended with the following options:
- The European lateral-torsional buckling curve, regulated in the German National Annex to EN 1993, for example.
- The adaptation for biaxial bending according to a dissertation by Dr. Naumes.
- The interpolation between lateral buckling and lateral-torsional buckling.
For the design of sets of members according to the General Method, there is a graphic implemented in Window 1.7 Nodal Supports - Sets of Members in RFEM and RSTAB displaying the nodal support on the set of members. In this way, the General Method represents a useful supplement to the other design methods, which has proven itself particularly when designing tapers.
