Optimum design of structural systems based on metaheuristic algorithms suffers from enormously time-consuming structural analyses to locate a reasonable design. In this paper an upper bound strategy (UBS) is proposed for reducing the total number of structural analyses in metaheuristic based design optimization of steel frame structures. The well-known big bang-big crunch algorithm as well as its two enhanced variants are adopted as typical metaheuristic algorithms to evaluate the effect of the UBS on computational efficiency of these techniques. The numerical results reveal that the UBS can significantly lessen the total computational cost in metaheuristic based design optimization of steel frames.

Upper Bound Strategy in Optimum Design of Truss Structures: A Big Bang-Big Crunch Algorithm Based Application Kazemzadeh Azad, Saeid; Hasançebi, Oğuzhan; Kazemzadeh Azad, Sina; Erol, Osman Kaan (2013-06-01) One main shortcoming of metaheuristic search techniques in structural optimization is the large number of time-consuming structural analyses required for convergence to a reasonable solution. This study is an attempt to apply the so-called upper bound strategy (UBS) as a simple, yet an efficient strategy to reduce the total number of structural analyses through avoiding unnecessary analyses during the course of optimization. Although, the usefulness of the UBS is demonstrated in conjunction with a big bang-...
Computationally enhanced techniques for practical optimum design of steel structures Kazemzadeh Azad, Saeid; Hasançebi, Oğuzhan; Department of Civil Engineering (2014) Practical optimum design of structural systems via modern metaheuristic algorithms suffers from enormously time-consuming structural analyses to locate a reasonable design. This study is an attempt to reduce the computational effort of optimization process involved in real-life applications through development of alternative techniques to the existing computationally expensive methods. Basically two main approaches are considered as (i) investigating the algorithmic structure of the existing metaheuristics ...
Improving the big bang-big crunch algorithm for optimum design of steel frames Hasançebi, Oğuzhan (null; 2012-01-01) This paper presents an improved version of the big bang-big crunch (BB-BC) algorithm namely exponential BB-BC algorithm (EBB-BC) for optimum design of steel frames according to ASD-AISC provisions. It is shown that the standard version of the algorithm sometimes is unable to provide reasonable solutions for problems from discrete design optimization of steel frames. Therefore, by investigating the shortcomings of the BB-BC algorithm, it is aimed to enhance the algorithm for solving complicated steel frame o...
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 ...
Harmony search algorithms in structural engineering Saka, M.P.; Aydogdu, I.; Hasançebi, Oğuzhan; Geem, Z.W. (2011-08-08) Harmony search method is widely applied in structural design optimization since its emergence. These applications have shown that harmony search algorithm is robust, effective and reliable optimization method. Within recent years several enhancements are suggested to improve the performance of the algorithm. Among these Mandavi has presented two versions of harmony search methods. He named these as improved harmony search method and global best harmony search method. Saka and Hasancebi (2009) have suggested...
