Abstract. The particle swarm optimization (PSO) method is utilized for two-dimensional steel frames featuring
semi-rigid connections between beams and columns, as well as between columns and bases. The metaheuristic
algorithm generates optimized steel frames by selecting suitable sections from a predetermined collection of
standard steel sections. The standard steel sections, which include wide-flange profiles (W), are supplied by the
American Institute of Steel Construction (AISC). The initial example is subject to displacement, inter-storey drift,
and stress constraints, as outlined by the AISC Load and Resistance Factor Design (LRFD) regulations. In the last
examples, the displacement, geometric, and stress constraints of the AISC Allowable Stress Design (ASD)
standard are implemented. In the course of the optimization process, three distinct steel frames are examined,
including configurations both with and without semi-rigid connections between the beams and columns, as well
as between the columns and bases. All optimization techniques are implemented using the high-level programming
language C# version 17.10.5, which is designed to integrate with version 22 of SAP2000's Open Application
Programming Interface (OAPI). The results of the analysis indicate that the rigidity of the connections serves as a
critical parameter in the optimization of weight for steel frames.
