Optimum design of high-rise steel buildings using an evolution strategy integrated parallel algorithm

2011-11-01
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 procedure, which provides an ideal platform for attaining optimal solutions in a timely manner without losing accuracy in computations. Three design examples from the category of high-rise steel buildings are studied extensively to demonstrate cost-efficiency of the algorithm in conjunction with a cluster of computers with 32 processors. The variation in performance of the parallel computing system with respect to the number of processors employed is also scrutinized in each design example. (C) 2011 Civil-Comp Ltd and Elsevier Ltd.

ISOPARAMETRIC ELEMENTS WITH UNEQUALLY SPACED EDGE NODES
UTKU, M; CITIPITIOGLU, E; OZKAN, G (Elsevier BV, 1991-01-01)
In the isoparametric finite element formulation, mapping of equally spaced nodes on the boundary of the master element to unequally spaced locations on the physical elements results in an unacceptable distortion. This type of distortion is defined as 'node mapping distortion' and a technique for its elimination is presented. Simple test cases demonstrate the utility of the new formulation.
Optimal design of planar and space structures with genetic algorithms
Erbatur, F; Hasançebi, Oğuzhan; Tutuncu, I; Kilic, H (Elsevier BV, 2000-03-01)
One of the most important practical considerations in the optimization of steel structures is that structural members are generally to be selected from available steel profiles. Furthermore, the solutions produced according to the national specifications are undoubtedly valuable from the point of view of applicability in real-life practice. This paper reports the development of a computer-based systematic approach for discrete optimal design of planar and space structures composed of one-dimensional element...
OPTIMIZATION AND SENSITIVITY OF PRESTRESSED CONCRETE BEAMS
ERBATUR, F; ALZAID, R; DAHMAN, NA (Elsevier BV, 1992-12-03)
This paper is concerned with the optimum design of prestressed concrete beams. Both minimum weight and minimum cost optimization formulations are given for simply supported beams having three different sections. Sensitivity of the optimum designs, with respect to various design parameters, are also discussed. The formulation is programmed for interactive use on micro-computers. An example is given and results are discussed.
Guided stochastic search technique for discrete sizing optimization of steel trusses: A design-driven heuristic approach
Azad, S. Kazemzadeh; Hasançebi, Oğuzhan; Saka, M. P. (Elsevier BV, 2014-04-01)
This study presents a design-driven heuristic approach named guided stochastic search (GSS) technique for discrete sizing optimization of steel trusses. The method works on the basis of guiding the optimization process using the well-known principle of virtual work as well as the information collected during the structural analysis and design stages. The performance of the proposed technique is investigated through a benchmark truss instance as well as four real-size trusses sized for minimum weight accordi...
