English abstract:
Loss of stability of multi-lamellae compression flanges of steel I-beams is characterized by joint buckling of the lamellae. This fact is ignored in engineering practice. Instead of it, the assumption of independent buckling of the individual lamellae is made. The smallest of the so-obtained buckling stresses is considered to be relevant for determination of the safety against buckling under service loads. The purpose of this paper is to present a method of solution of the combined stability and contact problem resulting from consideration of joint buckling of the lamellae.
