  3. Euler's critical load - Wikipedia

    en.wikipedia.org/wiki/Euler's_critical_load

    For loads greater than the critical load, the column will deflect laterally. The critical load puts the column in a state of unstable equilibrium. A load beyond the critical load causes the column to fail by buckling. As the load is increased beyond the critical load the lateral deflections increase, until it may fail in other modes such as ...

  4. Johnson's parabolic formula - Wikipedia

    en.wikipedia.org/wiki/Johnson's_parabolic_formula

    The slenderness ratio is an indicator of the specimen's resistance to bending and buckling, due to its length and cross section. If the slenderness ratio is less than the critical slenderness ratio, the column is considered to be a short column. In these cases, the Johnson parabola is more applicable than the Euler formula.

  7. Southwell plot - Wikipedia

    en.wikipedia.org/wiki/Southwell_plot

    Initially created for stability problems in column buckling, the Southwell method has also been used to determine critical loads in frame and plate buckling experiments. The method is particularly useful for field tests of structures that are likely to be damaged by applying loads near the critical load and beyond, such as reinforced concrete ...

  8. Buckling - Wikipedia

    en.wikipedia.org/wiki/Buckling

    Lateral-torsional buckling of an I-beam with vertical force in center: a) longitudinal view, b) cross section near support, c) cross section in center with lateral-torsional buckling. When a simply supported beam is loaded in bending, the top side is in compression, and the bottom side is in tension. If the beam is not supported in the lateral ...
