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.
It can also be extended by the following options:
~ The European lateral-torsional buckling line, which is regulated, for example, in the German National Annex to EN 1993.
~ The Extension for Biaxial Bending According to a Thesis by Dr. Ing. Naumes.
~ The interpolation between buckling and lateral-torsional buckling.
For the design of sets of members according to the General Method, a window has been implemented in RFEM and RSTAB in the window "1.7 Nodal Supports - Sets of Members" to display the nodal supports graphically on the set of members. Thus, the General Method is a useful addition to the other design formats, which has proven itself in particular when designing tapes.
