Abstract

Evolutionary optimisation methods, namely, Genetic Algorithms (GAs), Evolutionary Programming (EP) and Evolution Strategies (ESs) have received significant interest amongst researchers in the optimisation area. This paper deals with optimum design of structures using ESs. First, a brief review of structural optimisation and ES fundamentals are given. This is followed by the explanation of a computational procedure for size and/or shape and/or topology optimum design (minimum weight) of plane and space trusses subjected to stress, displacement and stability constraints, incorporating a mixed formulation in design variables. Finally, three numerical examples are presented and the results are compared with previously published works.
