Classification of steel elements' cross-sections from local stability aspects

The paper deals with the actual problems of steel elements' cross-sections classification according to local stability their webs and flanges subjected to bending and compression. The presented analysis is based on author's experimental-theoretical research. The presented relation Eu - Bata allows the optional web classification of steel elements in accordance with expected or select development of plastic strains. The presented relation Eu - Beta allows the optional web classification of steel elements in accordance with expected or select development of plastic strains. This approach is more suitable than contemporary standard uniform classification of cross-sections.
