OPTIMAL SIZE AND GEOMETRY DESIGN OF TRUSS STRUCTURES UTILIZING SEVEN META-HEURISTIC ALGORITHMS: A COMPARATIVE STUDY
Meta-heuristic algorithms are applied in optimization problems in a variety of fields, including engineering, economics, and computer science. In this paper, seven population-based meta-heuristic algorithms are employed for size and geometry optimization of truss structures. These algorithms consist of the Artificial Bee Colony algorithm, Cyclical Parthenogenesis Algorithm, Cuckoo Search algori...
متن کاملOPTIMAL DESIGN OF TRUSS STRUCTURES BY IMPROVED MULTI-OBJECTIVE FIREFLY AND BAT ALGORITHMS
The main aim of the present paper is to propose efficient multi-objective optimization algorithms (MOOAs) to tackle truss structure optimization problems. The proposed meta-heuristic algorithms are based on the firefly algorithm (FA) and bat algorithm (BA), which have been recently developed for single-objective optimization. In order to produce a well distributed Pareto front, some improvement...
متن کاملModified genetic algorithm for optimal design of truss structures
Truss systems are widely used in engineering practice, mainly due to the economy, simple manufacturing, transportation and storage. These systems form the framework of such constructions as bridges, towers, roof supporting structures, etc. Usually a truss system includes a large number of elements (trusses), which can have different parameters (length, cross-sectional area, shape of crosssectio...
متن کاملOptimal Design of Truss Structures with Frequency Constraints Using Interior Point Trust Region Method
Nowadays, in the industrial environment of simulation-based design, optimization has been widely applied. This article illustrates that how truss structural frequency optimization problems is being solved by interior point trust region method (IPTRM). As a possible way, primal-dual interior point method could optimize the structure by multiple centrality modifications with trust region subprobl...
متن کاملA Design Method for Optimal Truss Structures with Certain Redundancy Based on Combinatorial Rigidity Theory
Abstract The Truss Topology Design (TTD) problem deals with the selection of optimal configuration for pin-jointed trusses, in particular, the optimization of the connectivity of the nodes by the members, in which volume and/or compliance are minimized. In general, it is known that such truss structures are statically determinate and not redundantly rigid, that is, if just one member is damaged...
