Optimization task when calculating the bi-steel thin-walled rod

The building structures load-bearing elements (columns-pillars of the N-th profile) determining the optimal cross-sectional dimensions problem solution is proposed. The section elements have a bi-steel layout. The solution is based on sensing the multiple (LPT sequences) profile size combinations satisfying the structural and technological limitations. The area of optimal results is governed by the conditional quality criteria (mass, cost, rigidity).The building structures load-bearing elements (columns-pillars of the N-th profile) determining the optimal cross-sectional dimensions problem solution is proposed.
