Applying Optimization Techniques on Cold-Formed C-Channel Section Under Bending

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 macro determine cross-section The beam optimized according its flexural capacity and cross-sectional area. computed utilizing effective width method (EWM) accordance with Egyptian code. constraints were selected so that derived from would be production construction-friendly. Pareto solution obtained 91 sections. curve demonstrates possesses both diversity convergence objective space. there is between 1 1.5 millimeters thickness. solutions validated by conducting comprehensive parametric analysis change corresponding local buckling capacity. In addition, performing single-objective based on at thicknesses single indicate increasing elements, excluding lip depth, will increase section’s carrying However, this depend coil’s wall more rapid thicker coils than thinner ones.
