    Default The critical buckling load given by Euler's formula

    Hi,

    Is possible to calcultate the critical buckling load (elastic stability limit) given by Euler's formula (Fcr = EI<pi>^2/L^2)?

    Thanks!

    Hi,

    You can find the buckling (or critical) load by two ways in Robot; 1) by performing a buckling analysis and/or performing a 2) Non lineal (geometrical) analysis which stops until the structure collapse (due to the critical load)

    Both analysis works for your example (the classical Euler column) or for any other structure.

    I made the analysis that you proposed by the two ways. Find attached the files.

    Good luck!

    Nice example...till today I never tried those options and mostly because of the lack of documentations about those functions of Robot. Hope that someday I'll have time to do some research...
    Thanks Brhm!

    By conducting the non-linear analysis, how can see the value at which the structure collapses ??
