Abstract

An optimization method based on evolution strategies for minimum weight design of steel structures subjected to dynamic loading is presented. Constraints are placed on dynamic displacements, dynamic stresses and discrete values of member sizes. Evolution strategies imitate biological evolution and work simultaneously with a population of design points in the space of variables. This allows for an implementation on a parallel computer. In this paper the basic ideas and a parallelisation technique of evolution strategies for solving optimization problems with discrete variables are described. Several examples are presented to illustrate the features of the method.
