The work is devoted to bi‐criterion optimization of thin‐walled cold‐formed beams under pure bending. The first objective function is the area of a beam cross‐section and the maximum deflection of a beam is taken as the second one. The strength and stability constraints in bi‐objective optimization problem are taken into account and formulated analytically. Some results of numerical calculations are presented in the form of the tables. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
