Concept explainers

Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

Question

The column consists of a rigid member that is pinned at its bottom and attached to a spring at its top. If the spring is unstretched when the column is in the vertical position, determine the critical load that can be placed on the column.

Expert Solution

Step 1

Draw a free body diagram showing the forces acting on the column and the spring.

Here, P is the critical load, F_s is the spring force, k is the spring constant, and is the deflection of the column.

Write the formula for the spring force.
