Abstract There are no standard dimensions or shapes for cold-formed sections (CFS), making it difficult a designer to choose the optimal section in order obtain most cost-effective section. A great number of researchers have utilized various optimization strategies dimensions. Multi-objective CFS C-channel beams using non-dominated sorting genetic algorithm II was performed Microsoft Excel macr...

Parametric optimization problem of cross-sectional sizes for cold-formed C-profiles subjected to central compression has been considered by the paper. formulated as follow: define optimum taking into account post-buckling behavior and structural requirements when stripe width thickness well type profile are constant defined designer.
 Criterion load-bearing capacity maximization assumed pu...
