The continued effort for economic design of steel structures leads to decrease their weight by shape and material optimization through the using of thin webs, high-strength steels and their effective combination with usual structural steels. The efficiency of high-strength steels using and their combination with usual structural steels is evident in the case of beams mostly subjected to bending loading. But from the complex optimization analyses follow, that the using of high-strength steels and their combination with usual structural steels can be advantage also in the case of columns mostly subjected to compression loading, mainly in the case of thin-walled members. The paper will present basic information about realized experimental-theoretical research of the elastic-plastic load-carrying capacity of thin-walled compressed steel members with combined cross-sections. This research has been distinctively oriented on the investigation and analyses of local stability and post-critical behavior of the slender and ultra-slender member webs and their interaction with compact flanges in the process of their loading and failure. In accordance with this investigation the original calculation and design procedures will be presented in the paper.
