A simple methodology for calculating effective length factors for uniform and stepped crane columns with any values of relative shaft lengths, moments of inertia, loading, and boundary conditions is presented. The proposed approach can be applied easily without resort to using any special nomographs and charts for solutions. Numerical examples are given to demonstrate the validity of the approach.
