    The Optimum Design of Compressed Thin-Walled Columns of Open Cross-Section
    (2000) Manevich, Arkadiy I.; Raksha, Serhii V.
    ENG: The structural optimization problem for compressed thin-walled columns of open cross-section (channel and lipped channel) is considered on the base of the linear stability theory and the nonlinear interactive buckling theory. Optimal dimensionless parameters are presented as a function of a single leading parameter of load and geometry P* and imperfection amplitudes.

    Two-Criteria Optimization of H-Section Bars Under Bending and Compression
    (2006) Manevich, Arkadiy I.; Raksha, Serhii V.
    ENG: The two-criteria optimum design problem for thin-walled members with two axes of symmetry (of h-type) subjected to compression and bending is solved. Components of the objective function vector are the compressive force and the bending moment in the web plane. Pareto-optima and «compromise» optimal projects have been obtained and compared with standard profiles.

    Two-Criteria Optimization of Thin-Walled Beams-Columns Under Compression and Bending
    (2001) Manevich, Arkadiy I.; Raksha, Serhii V.
    ENG: A two-criteria optimization problem for thin-walled members of open cross-section with one axis of symmetry (of the channel type) subjected to compression or / and bending in the symmetry plane under stability constraints is solved. The objective function vector components are the axial compressive force and the bending moment. Optimal configurations of thin-walled members for marginal cases of loading – axial compression or pure bending – are obtained? Pareto-optima are constructed and «compromise» optimal projects are derived as a function of a single leading nondimensional parameter of weight. The obtained optimal projects are universal? In distinction from the optimal projects for special loading cases, and applicable under arbitrary combination of compression and bending. Comparison of standard profiles (specified by the design codes) with the optimal projects enables us to indicate «bad» standard profiles which are far from optimal ones under any loads.
