Elastic local buckling strength of I-beam cantilevers subjected to bending moment and shear force based on flange–web interaction

This research is aimed at investigating the elastic buckling strength of I-beam cantilevers. In section classification and in design both, understanding load that beam can withstand without loss stability crucial, especially determining correct method analysis. The divided into segments which are investigated separately as plates. A novel approximation for plates with flexible boundary conditions proposed, respect to their lengths. paper concludes a proposal an equation estimate whole beam.
