Szukana fraza: [Abstract = "The variants of solving tasks for thin\-wall metal frames have been developed, for which there is a discrepancy between the classification by stiffness of the column base and the initial design model. It\?s demonstrated on the principle scheme of the iteration process. With the help of numerical example, the problems which deal with classification of joints by stiffness on the final step of the optimal design of the thin\-wall metal frames were performed."]
