【 摘 要 】

Earlier, the criterion of minimum material consumption was formulated within the outline design of the I-shaped bar width and the stability constraints or restriction to the value of the first natural frequency in one principal plane of the cross-section inertia. In the distinctive paper, we formulate a criterion for the minimum material capacity of the I-shaped bar with a variation in its thickness and outline of the width, with restrictions on the value of the critical force or restriction to the value of the first natural frequency in two principal planes of the section inertia.
