Abstract

Structural optimization is a very well stablished design tool in several engineering fields when the problem is formulated with a single objective function and the feasible design region turns out to be convex. Nevertheless, many real problems lead to more complex formulations, sometimes because more than one local minima exist, or because more than one objective function must be included in the formulation. For such cases two procedures intended to enhance the capabilities of design optimization, namely, one approach to global optimization and a recent procedure to obtain sensitivity analysis in multiobjective optimization, are presented in the paper. 1. Single objective structural optimization Structural design of engineering problems by using optimization techniques is nowadays
