Many members of steel structures are subjected mostly to bending. In these members from the economical point of view is very useful to utilize also plasticity of structural steels. The elastic-plastic resistance of steel members subjected largely to bending depends in large measure on local stability of their compressed flanges and bending webs in decided cross-sections and areas. The real elastic-plastic behavior of the steel members and their bending webs and compressed flanges is complicated. Therefore, the representative experimental knowledge and results about the real elastic-plastic behavior and mechanisms of failure of the steel members have been very important from the scientific and practical aspects. The author of paper realized in previous time the wide experimental research within the range of this intention. The paper contains selected knowledge and results of the previous experimental-theoretical investigation of the elastic-plastic local stability of the steel members subjected mostly to bending. The adequate slenderness ? strain relation and methodology for practical calculation of the elastic-plastic bending resistance of the steel cross-sections and members are presented.
