EN The paper deals with cold-formed thin-walled beams with the Z-, S- and Clothoid-section. A short survey of optimal designs of thin-walled beams with open cross-sections is given. Geometric properties of three cross- sections are described. Strength, local and global buckling conditions for thin-walled beams are presented. The optimal design criterion with a dimensionless objective function as a quality measure is defined. Results of numerical calculations for optimal shapes of three cross-sections are presented in tables and figures.
PL W artykule rozważane są belki o przekrojach poprzecznych w kształcie Z-, S- oraz w kształcie klotoidy. Zamieszczono krótki przegląd zagadnień optymalnego projektowania belek cienkościennych o przekrojach otwartych. Opisano właściwości geometryczne trzech rozważanych przekrojów. Zapisano warunki wytrzymałości oraz lokalnej i ogólnej stateczności belek cienkościennych. Sformułowano kryterium optymalizacyjne z wykorzystaniem bezwymiarowej funkcji celu będącej miarą jakości przekroju. Wyniki numerycznych obliczeń optymalnych zarysów przekrojów poprzecznych przedstawiono w tablicach i na rysunkach.
