Buckling load and its equation
WebBuckling - Other End Conditions Buckling (Pin Ended Columns): For a column with pinned ends, we have the following conditions: 1. Force P that is applied through the centroid of the cross section and aligned with the longitudinal axis of the column. 2. Force P is guided such that P is always aligned with the pin joints 3. WebThe formula for the Euler buckling load is 10 (10.6) f c = − k π 2 E I L 2, where E is Young's modulus, I is the moment of inertia of the column cross-section, and L is column length. The value of k varies with the end conditions imposed on the column and is equal to the values given in Table 10.1. Table 10.1.
