The method of structural stability analysis utilized in this paper is a combination of the classical bending theory and the finite strip method. Combining the assumptions of traditional bending theory with the finite strip method yields a finite element model for axially loaded, simply supported, linear elastic members involving only three degrees of freedom which is suitable for use on microcomputers or even hand calculators. Examples of the application of the modified finite strip method to the buckling analysis of different types of steel compression members are presented.
