Weight Optimization of Tower Structures with Continuous Variables using Jaya Algorithm

Abstract

A popular metaheuristic algorithm named Jaya is preferred to solve the problem of finding the minimum weight of tower structures. Joints coordinates of free nodes and the area of bar elements are constrained using the lower and upper bounds of these design variables for shape and size optimization, respectively. The constraints used in this study are the Euler buckling, allowable stress, and displacement. The presented algorithm is tested with two classic benchmark problems: the spatial truss tower with 39-bar and the transmission tower with 272-bar. The Jaya algorithm is coded in MATLAB environment and implemented into the linear finite element solver.
