Column Buckling Calculator (Euler And Johnson)
Column Buckling Calculator (Euler And Johnson): a planned Super Calculator tool. Stub page: the tool, its formula and a worked example are not published yet.
Column Buckling Calculator (Euler And Johnson) is a planned calculator in the engineering section of Super Calculator, covering structural engineering.
What this calculator will compute
Inputs: length, end conditions, section properties or selection, elastic modulus, yield strength and eccentricity.
Outputs: critical buckling load, critical stress, slenderness ratio, effective length, buckling mode and allowable load with a safety factor.
Formula, recorded as scope and not yet verified against a primary source: Euler critical load P_cr = pi^2 EI/(KL)^2, where K is the effective length factor: 1.0 pinned-pinned, 0.5 fixed-fixed, 2.0 fixed-free. Valid only above the critical slenderness ratio; below it the Johnson parabolic formula or the code inelastic buckling curve governs.
