Design optimization of steel space frames is a very popular topic in structural engineering due to economy saved in cost of the structures by optimization process. Although the final cost of a steel frame is affected by many factors, such as material, manufacturing, erection and transportation costs, the material cost of steel comprises a great deal of overall cost of the structure. Hence, the design optimization of steel frames is focused on weight minimization in the literature based on the assumption that the use of least material leads to an economical design as well in terms of final cost of a structure. This study focuses on design optimization of steel space frames that are sized for minimum weight subject to stress, stability and nodal displacement and drift constraints according to Allowable Stress Design-American Institute of Steel Construction (ASD-AISC) specification. Bat inspired optimization (BIO) algorithm, which is a recently developed metaheuristic technique that exploits echolocation behavior of bats in searching a design space, is employed to deal with the optimization problem at hand. It is shown that BIO produces improved results with respect to other methods of metaheuristics.

Optimum Detailed Design of Reinforced Concrete Continuous Beams using the Harmony Search Algorithm Akin, A.; Saka, M. P. (2010-09-17) Design optimization of reinforced concrete structures is more challenging than that of steel structures due to the complexity associated with reinforcement design. In this study, optimum design algorithm is presented for reinforced concrete continuous beams. The design variables are selected as the width and the depth of beams in each span, the diameter and the number of longitudinal reinforcement bars along span and supports, and the diameter of ties. The design constraints are implemented from ACI 318-05 ...
Optimum design of high-rise steel buildings using an evolution strategy integrated parallel algorithm Hasançebi, Oğuzhan; Kurç, Özgür (null; 2009-12-01) The present study addresses a parallel solution algorithm for optimum design of large steel space frame structures, in particular high-rise steel buildings. The algorithm implements a novel discrete evolution strategy optimization method to effectively size these systems for minimum weight according to the provisions of ASD-AISC specification and various practical aspects of design process. The multitasking environment in the algorithm rests on a master-slave model based parallelization of the optimization ...
Evaluating Efficiency of Big-Bang Big-Crunch in Benchmark Engineering Optimization Problems Hasançebi, Oğuzhan; Erol, Osman Kaan (2011-06-01) Engineering optimization needs easy-to-use and efficient optimization tools that can be employed for practical purposes. In this context, stochastic search techniques have good reputation and wide acceptability as being powerful tools for solving complex engineering optimization problems. However, increased complexity of some metaheuristic algorithms sometimes makes it difficult for engineers to utilize such techniques in their applications. Big-Bang Big-Crunch (BB-BC) algorithm is a simple metaheuristic op...
Design optimization of truss structures using genetic algorithms Ünalmış, Dilek; Kayran, Altan; Department of Aerospace Engineering (2012) Design optimization of truss structures is a popular topic in aerospace, mechanical, civil, and structural engineering due to benefits to industry. Common design problem for the structures is the weight minimization. Especially in aerospace engineering the minimization of the weight of the total structure gets the highest importance in the design. This study focuses on the design optimization of 2D and 3D truss structures. The objective function is the total mass of the structure which is subjected to stres...
Optimum design of steel frames using stochastic search techniques based on natural phenomena: A review Saka, M. P. (2007-09-21) Recent developments in optimization techniques that deal with finding the solution of combinatorial optimization problems has provided steel designers with new capabilities. These new optimization techniques use nature as a source of inspiration to develop new procedures for solving complex engineering problems. Among these, evolutionary algorithms mimic evolutionary biology and make use of the principle of the survival of the fittest to establish a numerical search algorithm. In the immune system algorithm...
