Buckling calculation formula

WebIn structural engineering, Johnson's parabolic formula is an empirically based equation for calculating the critical buckling stress of a column.The formula is based on experimental results by J. B. Johnson from around 1900 as an alternative to Euler's critical load formula under low slenderness ratio (the ratio of radius of gyration to effective length) conditions.
