ST7-R3.10.10.6 Linear Buckling Analysis
To gain an appreciation for performing a linear buckling analysis and interpreting the results, it is important to keep in mind the fundamental question that the linear buckling solver answers, namely: How much load is needed to excite a structural instability? The linear buckling solver can only answer this question for structures whose deformation, up to the critical load, is negligibly small. Furthermore, it cannot predict what happens to the structure when the critical load is reached or exceeded.
