Um sistema automático de projeto de estruturas ótimas

A computer system for the automatic sizing of large-scale structures is developed, making use of an "optimali ty cri terion" algori thm, where inequali ty constraints are treated with the aid of slack-variables. Attention is focused on fixed geometry structures which can be idealized using finite elements. Multiple loading conditions are also considered. Element stresses, nodal displacements, and buckling of axialy compressed elements are considered as constraints. Methods of structural analysis, calculation of gradients of response functions and the general organization of the system are ihoroughly described. The mathematical foundations of the optimization algorithm,are also showed in condensed form. The automatic design of a variety of structural systems, allows to conclude that the system performance is efficient and competitive.
