Biogeography-Based Optimization Algorithm for Designing of Planar Steel Frames

Abstract

Abstract:The optimization can be defined as a solution of problem under specific conditions to achieve a specific purpose. Optimization strategies commonly used for solving of various problems and have gained great importance in recent years especially in engineering. Evolving optimization methods over the years has many varieties such as shape optimization, topology optimization, size optimization etc. The latest trend of optimization methods is metaheuristics which are more useful with easy applicable to complex problems regarding to traditional optimization methods. So that metaheuristics have supplanted the traditional methods particularly in engineering by the time. In this study, a planar steel frame which is designed according to the requirements comprised by AISC-LRFD (American Institute of Steel Construction-Load and Resistance Factor Design) has been optimized by aid of biogeography-based optimization (BBO) algorithm.

Enhancing transmission type frame structures: A BBO algorithm-based integrated design approach

“…Tunca and C ¸arbaş investigated the optimization of a planar steel frame designed according to AISC-LRFD (American Institute of Steel Construction-Load and Resistance Factor Design) requirements using the biogeography-based optimization (BBO) algorithm. The results indicate that the BBO algorithm performs excellently in the optimization of planar steel frame designs [41]. Despite these successes, the BBO algorithm faces challenges and difficulties, particularly in dealing with highly nonlinear and complex design spaces where the convergence to global optima can be slow.…”

“…Optimizasyon algoritmaları vasıtasıyla elde edilen sonuçların makul olabilmesi için tasarım kısıtlarının dikkate alınması gerekmektedir. Bu amaçla, Denklem (8)'de verilen bir ceza yöntemi uygulanmış amaç fonksiyonu, ihlal edilen toplam kısıtlar açısından kısmen uygun olmayan tasarımları dikkate almak için kullanılır [13]. Böylece, çözümün uygunluğu Denklem (8) temelinde değerlendirilir ve uygun olmayan çözümlerden kaçınılır.…”
