Linear elastic buckling of composite beams – An analytical engineering approach

This article outlines a concise and complete versatile novel analytical framework to quickly and effectively assess lateral shear and lateral torsional buckling of composite beams build of segments with different lengths. The adjective “composite” includes dissimilar beam profiles with symmetrical homogeneous and or inhomogeneous cross‐sections and distinct beam materials. The major aim is to provide engineers with an accurate, simple but elegant analytical beam buckling tool based on advanced solid theoretical propositions. The justification of the analytical theory is supplied by demonstration of executed numerical tests, which affirm the validity of the proposed analytical buckling models adapted to the considered beam buckling cases.
