Abstract
In this paper, a three-story two-span steel frame and a five-story irregular steel frame models are examined. Hunting Search algorithm (HuS), particle swarm algorithm (PSO), and Aquila algorithm (AO) are used to determine suitable frame sections. The performances of the algorithms are investigated with the welded beam design problem and the three-truss problems. The work consists of two stages as optimization and solution with finite element method. The aim of this study is to determine the frame section within the constraints to have a minimum weight. The models were created using the sections determined because of the optimizations are performed with finite element analysis. In steel frame structures, the provisions of the AISC-LRFD practice code are used. The analysis is done with the ABAQUS CAE program, which is one of the finite element methods. Frames with optimum sections are drawn and analyzed in the program. As a result of the analysis, the displacement and stress values are shown. These all values are within limits. PSO and HuS algorithms give the same results. The worst result is taken from the AO algorithm. © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
