Efficient Optimum Design of Structures--Program DDDU,
Abstract
An efficient optimization algorithm is developed for the engineering structures subject to multiple constraints. The highly non-linear and implicit problem is reduced to a sequence of quasi-linear constraints and explicit problems of the statically determinated structures. The method is based on the Kuhn-Tucker necessary conditions for optimiality associated with a simple quadratic programming to determine the lagrange multipliers and to delete non-active constraints simultaneously. A number of examples including trusses and wing structures show that the method is efficient when compared with other competing techniques.
