This calculator computes the critical load of the specified column. In addition, the boundary condition factor and the effective length of the column are also calculated.
Both theoretical and engineering results are presented. The theoretical critical load is obtained directly from the elastic buckling theory. The boundary conditions are considered to be perfect as specified. The engineering critical load is used in column design, where the ideal boundary conditions are approximated.

The critical load (Extended Euler's formula) for a column is given by,
where E is the Young's modulus, I is the area moment of inertia of the cross section, and Leff is the effective length of the column, which depends on the length of column as well as its boundary conditions.
