Variables Used

Buckling Load - (Measured in Newton) - The Buckling Load is the load at which the column starts buckling. The buckling load of a given material depends on the Slenderness ratio, Area of a cross-section, and Modulus of Elasticity.
Coefficient for Column End Conditions - Coefficient for Column End Conditions is defined as the multiplicative factor for different column end conditions.
Modulus of Elasticity - (Measured in Megapascal) - The Modulus of Elasticity is the measure of the stiffness of a material. It is the slope of stress and strain diagram up to the limit of proportionality.
Area Moment of Inertia - (Measured in Millimeter⁴) - The Area Moment of Inertia is a property of a two-dimensional plane shape which characterizes its deflection under loading. It is also known as the second moment of area or second moment of inertia.
Effective Length of Column - (Measured in Millimeter) - The Effective Length of Column can be defined as the length of an equivalent pin-ended column having the same load-carrying capacity as the member under consideration.

STEP 1: Convert Input(s) to Base Unit

Coefficient for Column End Conditions: 2 --> No Conversion Required

Euler's Formula for Critical Buckling Load Formula

LaTeX Go

Buckling Load = Coefficient for Column End Conditions*(pi^2)*Modulus of Elasticity*Area Moment of Inertia/Effective Length of Column^2
P_{Buckling Load} = n*(pi^2)*E*I/L^2

Column End Conditions

In this formula, the coefficient n accounts for end conditions. When the column
is pivoted at both ends, n = 1; when one end is fixed and the other end is rounded, n = 2; when both ends are fixed, n = 4; and when one end is fixed and the other is free, n = 0.25. The slenderness ratio separating long columns from short columns depends on the modulus of elasticity and the yield strength of the column material.
