This research investigates the application of multi-objective optimization methodologies in developing economically viable and structurally efficient spatial steel constructions. It emphasizes the significance of optimizing performance alongside cost reduction in practical engineering scenarios. The investigation encompasses the minimization of maximum horizontal displacement, the maximization of the first natural frequency of vibration, the maximization of the critical load factor concerning the global buckling mode of the structure, and weight minimization as primary objectives. Furthermore, the analysis integrates considerations for both local and global second-order effects. Moreover, it delineates a systematic framework for selecting optimal designs, employing three distinct evolutionary algorithms grounded in differential evolution coupled with a multi-criteria decision-making approach.
