The optimal problem in the structural design is an important issue in the engineering design. Various authors have analyzed the optimization of steel structures using algorithmic approaches. These techniques are generally grouped in deterministic or meta-heuristic techniques. From the introduction of structural optimization in the 1960’ up to now, various methods have been proposed. A genetic algorithm, is built and applied in this study using MatLab soft R2017a to a crossed beams system. The structural analysis is done with the direct stiffness method with constraints verification based on EuroCode 3:2005 criteria. Results are reported in the study.

The structural engineering design problem consist in an iterative process of design. Various authors have analyzed the optimization of steel structures using different algorithmic approaches. These techniques are generally grouped in deterministic or meta-heuristics. From the introduction of structural optimization in the 1960' up to now, various methods have been proposed. A GA genetic algorithm, is built and applied in this study using MatLab soft R2017a to crossed beams systems. The structural analysis is done applying the direct stiffness method with constraints verification based on EuroCode 3:2005 criteria. Results are reported in the study.
