This is an accurate calculation method and is applicable for any (portal) structure.

In general, it also leads to a more economical design.\u003C\u002Fli>\n\u003Cli>Euler buckling is taken into account in the analysis itself. If the structure buckles mechanically, then you don't find a solution.\u003C\u002Fli>\n\u003Cli>You are freed from (sometimes very questionable) buckling length calculations.

This too is often questionable.

How is that?\u003C\u002Fem>\u003C\u002Fp>\n\u003Cp>According to Eurocode EN 1993-1-1 art. 5.2.2 (7) a) no individual stability check for the members according to 6.3 is necessary if second order effects in individual members and relevant member imperfections (see 5.3.4) are totally accounted for in the global analysis of the structure. (Global initial sway imperfections and relatively initial local bow imperfections of members for flexural buckling).\u003C\u002Fp>\n\u003Cp>In \u003Cstrong>XFrame2D\u003C\u002Fstrong>, the global initial sway imperfections according to art. 5.3.2 (3) a) are taken into account automatically. However, the relatively initial local bow imperfections of members for flexural buckling according to art. 5.3.2 (3) b) are not.\u003C\u002Fp>\n\u003Cp>This means that the individual stability of the elements must be checked according to 6.3, whereby the buckling length may be set equal to the system length. According to art. 5.2.2 (7) b). By applying a geometric nonlinear analysis, the moments and forces are of course including all second-order effects.\u003C\u002Fp>\n\u003Cp>In almost most cases (99%) it is sufficient to set the buckling length equal to the system length. Occasionally, you may even want to set the buckling length smaller.
