%A Sych, Piotr %A Słoński, Marek %D 2021 %T Structural Design Optimization of Steel Beams and Frames with Web-Tapered Members Using the PSO-FEM Algorithm %K %X This paper presents an algorithm for structural design optimization of steel beams and frames with web-tapered members using the particle swarm optimization (PSO) algorithm and the finite element method (FEM). The design optimization is done in accordance with Eurocode 3 (EC 3) for the minimum mass. The proposed algorithm is more flexible and efficient than traditional design methods based on a trial and error approach. The effectiveness of the presented PSO-FEM algorithm is evaluated on examples of the size optimization of web-tapered members cross-section. The results show that the PSO-FEM algorithm is feasible and effective for finding useful designs. %U https://cames.ippt.pan.pl/index.php/cames/article/view/284 %J Computer Assisted Methods in Engineering and Science %0 Journal Article %R 10.24423/cames.284 %P 39-55 %V 28 %N 1 %@ 2956-5839 %8 2021-02-12
