Here an example of Euler buckling in a grain storage facility is documented.

Euler Column Buckling: General Observations •buckling load, P crit, is proportional to EI/L2 •proportionality constant depends strongly on boundary conditions at both ends: •the more kinematically restrained the ends are, the larger the constant and the higher the critical buckling load (see Lab 1 handout) •safe design of long slender Metal building and steel framed structures are mostly affected by Euler buckling as they are erected structures. According to (Goraily,2008,pg 1- 17)“ Euler buckling .Euler buckling is one of the most celebrated instabilities of classical elasticity “.Euler load is the largest practical load that can be applied to a bar. The Euler Buckling Formula is: where L e is the effective length of the column. The column is fixed-free for buckling about both x- and y-directions. For a fixed-free column, the effective length is: L e = 2L = 4.4 m. The column may buckle about the x- or y- axis. The moment of inertia for a rectangle is: The Euler column formula can be used to analyze for buckling of a long column with a load applied along the central axis: In the equation above, σ cr is the critical stress (the average stress at which the column will buckle), and P cr is the critical force (the applied force at which the column will buckle).

The strut can remain straight for all values of P. 2 2 λ EI cr π 2. Under incremental loading, when P reaches a value of = P 31.9% of the design Euler buckling load.

The Critical buckling load analysis (also known as Eigenvalue buckling analysis) examines the geometric stability of models under primarily axial load. Buckling can be catastrophic if it occurs in the normal use of most products. Once the geometry starts to deform, it can no longer withstand even a fraction of the initially applied force. •Stability and Buckling（稳定性与失稳） •Examples of Columns（压杆应用示例） •Conventional Design of Columns（压杆的常规设计方法） •Euler’s Formula for Pin-ended Columns（端部铰接压杆欧拉公式） •Buckling Modes（失稳模态） •Extension of Euler’s Formula（欧拉公式的扩展） » Euler Buckling Formula The critical load, P cr, required to buckle the pinned-pinned column is given by the EULER BUCKLING FORMULA.

The term "L/r" is known as the slenderness ratio.

The Euler column formula predicts the critical buckling load of a long column with pinned ends. The Euler formula is column and its potential buckling, and identify the associated (Solution for) Euler Buckling Example: a wood pointer-- assume it is pinned and about 4. Euler's Formula.

In most applications, the critical load is usually regarded as the maximum load sustainable by the column. Theoretically, any buckling mode is possible, but the column will ordinarily deflect into the first mode. 2014-06-17 Buckling is a failure mode which occurs in long slender structural members, before a plastic deformation, such as yielding or crushing can happen.
