Castellated beams have garnered increasing attention in various fields due to their aesthetically appealing design, diverse geometric shapes, environmental friendliness, and economic advantages in terms of time, cost, and performance. These beams particularly excel in resisting bending without increasing their weight. The novelty of this paper, is to optimize the performance of castellated beams by maximum vertical deflection, represented as the objective function. This is achieved by determining the optimal dimensions of the cross-section using three optimization algorithms: Gray Wolf Optimization (GWO), Particle Swarm Optimization (PSO), and Differential Evolution (DE). This study focuses on three different types of material for castellated beams: S235, S255, and S355. The results revealed that the PSO and DE algorithms produce very similar outcomes, while the GWO algorithm shows slightly different results. Overall, all three algorithms demonstrate good capability in engineering applications, with a slight preference for the PSO and DE algorithms.

Petek kirişler, estetik açıdan çekici tasarımları, farklı geometrik şekilleri, çevre dostu olmaları ve zaman, maliyet ve performans açısından ekonomik avantajları nedeniyle çeşitli alanlarda giderek artan ilgi görmektedir. Bu kirişler özellikle ağırlıklarını arttırmadan eğilmeye karşı direnç gösterme konusunda mükemmeldir. Bu çalışmada, petek kirişlerin performansı, amaç fonksiyonu olarak temsil edilen maksimum düşey sapma ile optimize edilmiştir. Bu, üç optimizasyon algoritması kullanılarak kesitin optimal boyutlarının belirlenmesiyle elde edilir: Gri Kurt Optimizasyonu (GWO), Parçacık Sürü Optimizasyonu (PSO) ve Diferansiyel Evrim (DE). Bu çalışma petek kirişler için üç farklı malzeme türüne odaklanmaktadır: S235, S255 ve S355. Sonuçlar, PSO ve DE algoritmalarının çok benzer sonuçlar ürettiğini, GWO algoritmasının ise biraz farklı sonuçlar verdiğini ortaya çıkardı. Genel olarak, üç algoritmanın tümü, PSO ve DE algoritmalarını çok az fark bir şekilde tercih ederek, mühendislik uygulamalarında iyi bir yetenek sergilemektedir.
