Elasticplastic Bending Load-Carrying Capacity of Steel Members

Popis výsledku v původním jazyce

Many members of steel structures are subjected mostly to bending. In these cases can be especially very useful to use by resources also plasticity of structural steels. Therefore, the new international and national standards for the design of steel structures allow the elastic and plastic calculation methods and procedures. The elastic-plastic bending load-carrying capacity of steel members depends in a high degree on local stability of their webs and flanges. From local stability aspects the steel members can have compact or slender cross-sections. The compactness of steel cross-sections is only relative. It depends on the loading level or material utilization, and on the buckling resistance of their webs and flanges in the most loaded cross-sections and areas. The judgment of steel cross-sections compactness in this content is complicated stability problem. The new standards for the design of steel structures contain the specific classification of the cross-sections due to dimensions and slenderness of their compression and bending parts. The paper contains the results of the experimental-theoretical investigation of the elastic-plastic local stability and load-carrying capacity of steel members. The proposed methodology enables the elastic-plastic calculation of the cross-section bending resistance depending from the limit development of plastic strains.
