I`m doing a buckling analysis on a "simply-supported" pinned-end solid beam (IPE-profil) with high slenderness ratio and with a
concentraded/stationary load on the middle on top of the topflange. The topflange is retained against rotation about the
x-axis (the beams neutral axis). The results from the simulation then show buckling of the web. The load is 1 N, so the critical buckling load
will be 1 N multiplied with the BLF if I understanded this correctly?
The main question:
The critical buckling load is based on Euler`s theory and elastic behavior, right?
How do I decide the factor of safety in witch im searching for the design buckling load?
I have read that a safety factor of 4 is a good estimate, but how is this number determined?
