Fixed free column buckling
WebEuler Buckling Theory is the classical theory presented in textbooks and classrooms. It begins simply by noting that the internal bending moment in a loaded and deformed column is −P y − P y where P P is the compressive load and y y is the column deflection. So insert −P y − P y in for M M in the beam bending equation, EI y′′ = M E ... http://web.mit.edu/16.20/homepage/9_Buckling/Buckling_files/module_9_with_solutions.pdf
Fixed free column buckling

WebFailure of the column will occur in purely axial compression if the stress in the column reaches the yield stress of the material (see §5.2). On the other hand, if the critical buckling stress cr is less than the yield stress, then the column will fail by buckling before the yield stress is reached. Eqn. 7.5.12 is plotted in Fig. 7.5.2.

WebFor instance, in the case of a fixed-free column, we can substitute Le = 2L and obtain. The effective length is often expressed in terms of an effective-length factor K: Le = KL Where L is the actual length of the column. Thus, the critical load is Pcr = π2EI / KL2 WebThe column is free from initial stress. The weight of the column is neglected. The column is initially straight (no eccentricity of the axial load). Pin joints are friction -less (no …
