Petek kirişlerin kullanımı, çok yönlü mimari özellikleri nedeniyle son dönemde büyük ilgi görmektedir. Bu özellikler, farklı şekillerde boşluk içeren belirgin geometrik formları kapsamaktadır. Petek kirişler, artan eğilme mukavemeti sağlayarak hem ekonomik hem de çevresel açıdan faydalıdır; ayrıca, ağırlık artışı olmaksızın üretim teknikleri sayesinde kesit direncini artırmaktadır. Bu kirişler hastaneler, depolar, otoparklar, okullar ve alışveriş merkezleri gibi çeşitli yapılarda kullanılmaktadır. Bu çalışmada, altıgen boşluklu petek kirişlerin performansı S235, S255 ve S355 olmak üzere üç farklı malzeme kullanılarak optimize edilmiştir. Optimum kesit boyutları, düşey yer değiştirmeyi temsil eden bir amaç fonksiyonu yardımıyla belirlenmiştir. Optimizasyon için çiçek tozlaşması algoritması (FPA), ateş böceği algoritması (FA) ve yarasa algoritması (BA) olmak üzere üç farklı meta-sezgisel algoritma kullanılmıştır. Üç algoritmanın karşılaştırma sonuçları, ateş böceği ve çiçek tozlaşması algoritmalarının benzer sonuçlar verdiğini ve çiçek tozlaşması algoritmasının uygulama açısından en uygun algoritma olduğunu göstermiştir.

Deflection Optimization of Castellated Beams Using Three Different Meta‑heuristic Algorithms

Öz

The usage of castellated beams has recently attracted great attention due to their versatile architectural features. These include distinct geometric forms containing web openings in different shapes. Castellated beams are economically and environmentally beneficial by providing increased flexural rigidity without increasing their weight by changing production techniques. These beams are used in various structures such as hospitals, warehouses, parking lots, schools, and shopping malls. In this study, the performance of castellated beams with hexagonal web openings is optimized for three different materials such as S235, S255, and S355. The optimum section dimensions are computed using an objective function representing the maximum vertical displacement of the beam. Three different meta-heuristic algorithms, namely, the flower pollination algorithm (FPA), firefly algorithm (FA), and bat algorithm (BA), are employed. The comparison results of the three algorithms showed that firefly and flower pollination algorithms have similar results and the flower pollination algorithm is the most suitable for engineering applications.
