WebThe critical effective slenderness ratio may be found by equating F col as found by the Euler formula to that value as found by Equation (2-11). This procedure involves solving a cubic equation and will not be presented here since values of the critical slenderness ratio are tabulated in Table 2-3. WebThe formula is based on empirical results by J. B. Johnson from around 1900 as an alternative to Euler's critical load formula under low slenderness ratio conditions. Buckling refers to a mode of failure in which the structure loses stability. It is caused by a lack of structural stiffness.
