Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

To calculate the maximum axial loads for a column based on yielding and buckling about both axes, and allowing for factors of safety. The critical load P for buckling of a column depends on the vertical distance between supports and how the column is connected to those supports. The length L in the T'EI formula Per =- is the distance between points of zero moment. For a pin- L2 supported column, this is the full height of the column. For a column that is not pinned at both ends, the points of zero moment are not at the supports. The equation for the critical load can be modified to use an effective length Le = KL, where K depends on the support conditions. For a column fixed at both ends, K = 0.5. For a column fixed at one end and pinned at the other, K = 0.7 (Figure 1). The equation for the critical load then becomes ’EI Pa (KL)²
