Minimum Weight of Open Section Thin-Walled Structural Elements Under Stress Constraint
Abstract
This paper deals with the problem of optimization of thin-walled open sections. They are
subjected to the bending and to the constrained torsion. The particular attention is paid to the
structural optimization methods. The optimal weight of the structures is obtained starting from
some initial values of thicknesses and cross-sectional areas. The analytical and numerical
approaches are derived for structural elements of different shapes of the open cross-section
elements subjected to several loading cases. Optimization parameters have been determined by
Lagrange’s multipliers method. The obtained results are used for numerical calculation.
