Layout optimisation of trusses using simulated annealing

2002-07-01
This paper addresses to the development of a simulated annealing (SA) based solution algorithm for the simultaneous optimum design of truss type structures with respect to size, shape and topology design variables. The proposed algorithm is designed in such way that together with applicability to practical design problems, it also aims to produce efficient and improved design solutions for the problems of interest. From the practical point of view, the objective chosen is to minimise the weight of the structures under a set of particular constraints imposed by design code specifications on nodal displacement, member stress and stability. Concerning the efficiency of the algorithm, SA is adapted to be able to work fruitfully in the design spaces of complex problems occupied by many regions of highly different characteristics. The proposed algorithm is tested on two large design example problems taken from the literature for comparison purposes and the results are fully discussed.

Optimizing Single-Span Steel Truss Bridges with Simulated Annealing
Hasançebi, Oğuzhan (2010-11-01)
This study presents applications of a simulated annealing integrated solution algorithm to the optimum design of single-span steel truss bridges subjected to gravity loadings. In the optimum design process of a bridge the members are sized simultaneously as the coordinates of the upper chord nodes are determined such that the least design weight is attained for the structure. The design constraints and limitations are imposed in accordance with serviceability and strength provisions of ASD-AISC (Allowable S...
Optimum topological design of geometrically nonlinear single layer lamella domes using harmony search method
Çarbaş, Serdar; Saka, Mehmet Polat; Department of Engineering Sciences (2008)
Harmony search method based optimum topology design algorithm is presented for single layer lamella domes. The harmony search method is a numerical optimization technique developed recently that imitates the musical performance process which takes place when a musician searches for a better state of harmony. Jazz improvisation seeks to find musically pleasing harmony similar to the optimum design process which seeks to find the optimum solution. The optimum design algorithm developed imposes the behavioral ...
Optimal load and resistance factor design of geometrically nonlinear steel space frames via tabu search and genetic algorithm
DEĞERTEKİN, SADIK ÖZGÜR; Saka, M. P.; HAYALİOĞLU, MEHMET SEDAT (Elsevier BV, 2008-01-01)
In this paper, algorithms are presented for the optimum design of geometrically nonlinear steel space frames using tabu search and genetic algorithm. Tabu search utilizes the features of short-term memory facility (tabu list) and aspiration criteria. Genetic algorithm employs reproduction, crossover and mutation operators. The design algorithms obtain minimum weight frames by selecting suitable sections from a standard set of steel sections such as American Institute of Steel Construction (AISC) wide-flange...
Design methods for planar and spatial deployable structures
Kiper, Gökhan; Söylemez, Eres; Department of Mechanical Engineering (2011)
This thesis study addresses the problem of overconstraint via introduction of conformal polyhedral linkages comprising revolute joints only and investigation of special geometric properties for the mobility of such overconstrained linkages. These linkages are of particular interest as deployable structures. First, planar case is issued and conditions for assembling irregular conformal polygonal linkages composed of regular and angulated scissor elements are derived. These planar assemblies are implemented i...
